Description
Technical Field
The utility model belongs to the technical field of relay for the transformer protection, especially, relate to gas relay.
Background
The gas relay for protecting the oil-immersed transformer supplied in the current market has the functions of light gas and heavy gas protection, and when the transformer has light gas or heavy gas faults, the gas relay is provided for the protection equipment of the transformer in a contact signal output mode, so that the purpose of protecting the transformer is realized by sound and light alarm or cutting off the power supply of the transformer.
The main contents of the light gas are as follows:
1) air enters the transformer because the oil filtering and refueling or the cooling system is not tight;
2) the oil level is lower than the gas relay light gas buoy due to temperature reduction or oil leakage;
3) a small amount of gas is generated due to the fault of the transformer;
4) and a ride-through fault occurs.
The heavy gas comprises the following main contents:
1) serious faults occur inside the transformer;
2) and the gas loop has a fault;
3) and a traversing fault occurs in the near zone.
For example, a QJ-50 gas relay is shown in FIG. 4. The left and right interfaces of the shell are communicated with oil in the transformer, and all parts in the cavity of the shell are immersed in the transformer oil when the transformer operates. The oil groove is also filled with oil and is connected with the counterweight through a rod. The counterweight and the oil tank are supported by the shaft 2, and the oil tank is maintained in a horizontal position in the oil in a lever mode. The counterweight can adjust the distance between the counterweight and the shaft 2 through the threads on the rod, and adjust the balance moment to ensure that the oil groove is in a horizontal state in the transformer oil.
When the transformer is subjected to phenomena of temperature drop, oil leakage and the like due to light gas, the liquid level of oil in the transformer can be lowered, and when the liquid level of the oil is lowered to be lower than the upper opening of the oil groove, the transformer oil in the oil groove can not flow out. When the liquid level of the oil continues to descend, the oil groove is reduced by the buoyancy of the transformer oil, the gravity of the oil groove is increased, and the oil groove starts to rotate clockwise to descend under the action of the lever principle. When the liquid level of the transformer oil drops to a set position, the magnet 2 fixed outside the oil groove is close to the reed pipe 2, the contact in the reed pipe 2 acts, the contact signal is sent into the junction box through the lead and the binding post, the contact signal is sent to the protection equipment of the transformer by the other end of the binding post in the junction box, an audible and visual alarm signal is sent out or the power supply of the protection equipment of the transformer is cut off, and the transformer is protected to prevent further expansion of accidents. This part of the protection provides the output contact signal for the light gas fault of the transformer.
If the transformer is seriously failed inside due to heavy gas. Due to local overheating and the like, the oil inside the transformer generates a surge phenomenon, and the surge direction is from the left port to the right port of the shell. The flow velocity plate is pushed by the inrush current, so that the flow velocity plate rotates counterclockwise about the shaft 1. The flow velocity plate drives the attached magnet 1 to swing right at the same time, and when the magnet 1 approaches the reed pipe 1 to a certain distance, the reed pipe 1 sends out a contact signal. This signal is sent to the inside of the junction box through the wire and the terminal in the housing. The external protective device receives contact signals from the terminals in the terminal box.
The interior of the junction box and the space in the cavity of the shell are sealed and isolated from each other.
In fig. 4, 01 is a housing; 02 is a magnet 1; 03 is a flow velocity plate; 04 is a reed switch 1; 05 is a shaft 1; 06 is a counterweight hammer; 07 is shaft 2; 08 is a junction box; 09 is a binding post; 010 is an oil groove; 011 is a magnet 2; 012 is a dry reed pipe 2.
Disclosure of Invention
As shown in fig. 1, the present invention is to change the lever type structure of the oil tank of the light gas protection part into the floating block type structure. The specific gravity of the first floating block 9 is smaller than that of the transformer oil, and the first floating block 9 can move up and down along the guide rod 7. When the casing 1 is filled with transformer oil, the first floating block 9 floats to the upper limit position under the action of buoyancy. When the level of the transformer oil drops, the first float 9 will also drop as the oil level drops. Firstly, when the floating block 9 descends to a set position, namely a light gas alarm position, the second magnet 10 fixed on the first floating block 9 approaches to the second reed pipe 8, and a contact in the second reed pipe 8 is enabled to act. The contact signal of the second reed switch 8 is sent to the protection equipment of the transformer through a lead wire and a binding post in the shell 1 and a junction box of the gas relay. The purpose of acousto-optic alarm or power supply cut-off is realized, and the transformer is protected to prevent the expansion or spread of accidents caused by the transformer. The utility model discloses this part's advantage is: compared with the QJ-50 type gas relay, the gas relay has the advantages that the used parts are few, the adopted floating block 2 structure is simpler, and the gas relay is not easy to deform or crack. The originally adopted oil groove and the lever fulcrum part are structurally complex and easy to crack, so that the action of the gas relay is influenced, and a contact signal cannot be output.
For heavy gas parts, the utility model adds a memory device 14 in the shell 1. The purpose of the device is to give a memorable indication to the action of the flow velocity plate 3 when the heavy gas fault occurs, and not only the contact signal is output by the first dry reed pipe 4. This action indication also includes the flow rate plate 3 action that may occur without the first reed switch 4 being triggered. That is, as long as the flow rate plate has a relatively significant motion, it can be recorded by the memory device 14. The advantage of adding a memory device 14 is that it is easy to directly determine the type of accident. The pointer 17 is painted with red paint for convenient observation, and the method has great benefit for identifying the accident type and the equipment state quickly by equipment maintenance personnel.
When heavy gas occurs, the flow velocity plate 3 is driven by the oil surge flow and rotates counterclockwise around the first shaft 5, the protrusion on the flow velocity plate 3 strikes the lower portion of the memory device 14, so that the memory device 14 rotates counterclockwise around the second shaft 12. The memory device 14 is provided with a second floating block 18, and when the memory device 14 rotates anticlockwise to the right side of the vertical center line of the second shaft 12 for a certain angle, the second floating block 18 continues to enable the memory device 14 to rotate anticlockwise under the action of buoyancy. Until the sliding column 19 on the memory device 14 is limited by the upper end of the circular arc hole of the limit plate 13, the memory device 14 can not rotate any more. In this case, the angle of rotation of the pointer 17 on the memory device 14 has a visually significant indicating effect.
A third magnet 16 is fixedly mounted on the memory device 14 and serves to indicate the resetting of the memory device 14. Because the space in the housing of the gas relay is filled with transformer oil and is closed, the third magnet 16 cannot be directly reset after the heavy gas fault is relieved, namely, a magnet is used outside the gas relay to attract the third magnet 16 on the memory device 14 through the observation window, and the memory device 14 is pulled back to the initial position. The initial position is located on the left side of the vertical center line of the second shaft 12, the memory device 14 is limited by the limiting plate 13 to rotate clockwise continuously, and the buoyancy of the transformer oil can not enable the memory device 14 to rotate continuously to be located.
The reed switch is a commercial product.
