Description

Closed switchgear auxiliary electric inspection trolley

technical field

The utility model relates to the technical field of electric testing equipment for closed switch cabinets.

Background technique

At present, more than 90% of the 10kV power distribution cabinets in the substation are fully enclosed, and the line and busbar equipment are turned over to check whether there is no voltage. Direct power inspection is an important condition. According to the relevant requirements of the "Electrical Safety Work Regulations", when the equipment is powered off for maintenance (or line maintenance), it is necessary to install a grounding wire. When the operator transfers the equipment from the working state to the maintenance state, the power inspection is first required. Based on the protection of the operator's personal and operational safety, the electrical inspection program is very necessary.

Because the 10kV switchgear is fully enclosed, there is no place for actual electrical testing in the busbar and outlet cabinets, so the normal operation of the 10kV line transfer maintenance work is to hang the grounding wire after it is verified that there is no voltage on the line side. The current situation is that because the switchgear is a fully enclosed structure, the operator cannot directly test the electricity, and can only rely on the live display device equipped with the equipment itself. The change of the data is used to judge whether the line is charged, and the unreliable operation of some display devices will also cause misjudgment by the operator. If the closed bus bridge and closed switchgear are turned over for inspection and maintenance, if only relying on indirect electrical inspection, there will be a risk of misoperation, which will cause electric power safety production accidents.

The movable bending plate is detachable, which is convenient to install on the line side, bus side, switch, etc. Different positions on the side are beneficial to the electric test of different cabinets. The setting of the handle and rollers makes the operation easier and more convenient for the operator to operate. The positioning pin of the positioning mechanism can limit the position of the car body to avoid the operation process after the car body is pushed into place. Sliding displacement occurs in the center, and the setting of 6 detection holes can facilitate the detection of the incoming and outgoing wires of the switch by electric probes or infrared rays according to actual needs. The utility model has the advantages of simple structure, convenient use, safe and reliable operation, enables the closed switchgear to have the function of direct electric inspection, avoids misoperation caused by indirect electric inspection, and reduces the risk of human error in judgment.
