Abstract
The utility model discloses a fully-closed upper shield miniature bus-bar combination device, which comprises soft metal wires. An insulation layer is wrapped on the outside of each soft metal wire and provided with different colors. The device further comprises connecting terminals connected with the soft metal wires, and the insulating connecting terminals are fully-closed. The device as a combination device of the insulating terminals and the colorful insulating soft copper wires overcomes shortcomings of unsafe running and inconvenient maintenance of conventional protective miniature bus-bars. When being used in an A phase, a B phase, a C phase and an N phase of a voltage circuit, the device omits tag hanging of a conventional upper shield bus-bar, saves time and avoids unsafe factor of short circuit due to the tag hanging. In general, the device lowers labor intensity of workers, and the workers have no power operation, thereby reducing danger, effectively lowering secondary voltage failure frequency, simultaneously enhancing operation reliability of a protective device, and having important effect on safe operation of electrical equipment and a whole power grid.
Description
Technical field
The utility model relates to the substation secondary device field, especially relates to a kind of screen and pushes up little bus composite set.
Background technology
The transformer station of operation screen top secondary voltage bus all is exposed operation now, though when normal operation, there is the plastic jacket of insulation exposed bus top, can prevent the short circuit that foreign matter drops and causes, but when secondary connection, exposed bus spacing is very little, generally has only 3-5cm, and spacing is too small to be easy to cause short circuit when using instrument such as screwdriver.In addition, the lead of copper rod and copper rod junction is meticulous, causes in the running phenomenon that connecting line burns out can repeatedly take place.
In process is renovated in protection; withdrawing from also of old protection screen has difficulties; because when transforming,, can not put in order the power failure at station owing to be subjected to the restriction of each side factors such as power failure scheme; generally only stop transport and need the circuit of transformation; this just need chargedly cut off operating screen top bus, owing to do not have special-purpose cutting tool, if utilize clamp to cut copper rod; unavoidably can cause the short circuit of voltage circuit, influence the reliability service of protective device.
The utility model content
The purpose of this utility model is to provide a kind of little bus composite set of effectively avoiding short circuit when charged wiring, when operation such as cutting off.
The technical solution of the utility model is:
Totally-enclosed screen pushes up little bus composite set, and it comprises the metal flexible cord, and described metal flexible cord is wrapped with insulating barrier, and described insulating barrier has different colours.
It also comprises the binding post that is connected with the metal flexible cord, and described binding post is totally-enclosed insulation.
The utility model is the composite set of insulated terminal and color separation insulation annealed copper wire; overcome the shortcoming that the little bus operation of existing protection is dangerous, safeguard inconvenience; when the A that is used for voltage circuit, B, C, N phase time; saved the link that former screen top bus is listed; save the time, also avoided causing when listing the unsafe factor of short circuit.Can guarantee to shield the little bus integral body in top during operation and insulate,, also can not cause short circuit even there is metallic foreign body to drop on the little bus; Can guarantee charged easy-to-connect, safety when carrying out technological transformation; In addition, its terminal hardness is big, can recycle, and greatly reduces the cost of transformation.Generally speaking, it has reduced labor strength, and the workman does not need hot line job; danger reduces; effectively reduce the secondary voltage failure-frequency of transformer station, improved the operational reliability of protective device simultaneously, important function has been played in the safe operation of power equipment and whole electrical network.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of auxiliary bus-bar joint.
Embodiment
As shown in Figure 1, the utility model comprises four copper flexible cords 1, is respectively applied for A, B, C, the N phase of voltage circuit, and the external packets of copper flexible cord 1 is wrapped with insulating barrier, and copper flexible cord 1 adopts BVR35 copper flexible cord.The insulating barrier of copper flexible cord 1 outer wrapping adopts rubber, the color of rubber be yellow, green, red, black four kinds, so just be convenient to very much differentiation.Be surrounded by rubber because copper flexible cord 1 is outer, in the time of just can preventing wiring owing to drop because of carelessness spanner, screw etc. cause problem of short-circuit.
Auxiliary bus-bar joint 2 adopts totally-enclosed insulation, shows as Fig. 2, is enclosed with insulating barrier 6 at the skin of terminal body 5.Simultaneously, can make auxiliary bus-bar joint thinner, such as thinner 1/3 than existing, unit length just can be installed more multiterminal like this.Auxiliary bus-bar joint 2 is elegant in shape, attractive in appearance, generous, insulate, and the security reliability height, in addition, the base designs of terminal becomes double track, and to adapt to existing track far away, near, push-and-pull is convenient.
During use, four copper flexible cords 1 are connected between the adjacent protection screen 3,4, because employing is the copper flexible cord, and the remaining more than reservation 10cm between screen and the screen, when needs withdraw from certain protection screen, just can cut off bus.
Claims (2)
1. totally-enclosed screen pushes up little bus composite set, it is characterized in that: it comprises the metal flexible cord, and described metal flexible cord is wrapped with insulating barrier, and described insulating barrier has different colours.
2. totally-enclosed screen according to claim 1 pushes up little bus composite set, it is characterized in that: it also comprises the binding post that is connected with the metal flexible cord, and described binding post is totally-enclosed insulation.
