Description
Technical field
The protection field of ground wire connecting tool in transmission line of electricity is the utility model is related to, specially a kind of ground wire connection
Gold utensil secondary protector, match somebody with somebody suitable for 35KV and the above, major network power circuit, electrical part and lightning protection portion ground wire above shaft tower
Be fixedly connected.
Background technology
To match somebody with somebody in 35KV and the above, major network power circuit, electrical part is fixedly connected with mode with lightning protection portion ground wire above shaft tower,
General sequence is connecting tool --- insulator --- connecting tool --- wire；Connecting tool --- lightning conducter, one-to-one company
Connect.And when circuit is across high-risk facilities such as high ferros, according to Guo Wang companies general plan, adjacent two base shaft towers insulator is necessary for
Two-in-series connects, but this behave only enhances anti-stretching load in insulation division, and the former one-to-one anti-load intensity of connecting tool does not change
Becoming --- a lot of circuits of Guo Wang companies accident safe for operation shows, due to each external force factor of spontaneous induction, the bar of fixed ground wire
Tower gold utensil, run by certain time fatigue, part gold utensil internal structure will appear from different degrees of intensity regression.If change and
When, the ground wire security incident that comes off can also avoid, can not conversely, can then lead to that power network disintegrates, high ferro is stopped transport, is blocked at a high speed etc.
Control, influence the larger particularly serious safety responsibility accident in face.Therefore a kind of ground wire connecting tool secondary protector is needed, to connection
Gold utensil plays the effect of being effectively protected.
The content of the invention
The utility model in order to solve the problems, such as it is electric with lightning-arrest ground wire on connecting tool regression, there is provided one kind is led
Ground wire connecting tool secondary protector.
The utility model is achieved by the following technical solution.
A kind of ground wire connecting tool secondary protector, including steel plate, the both ends of the steel plate are separately installed with right angle
Steel plate I, the i.e. horizontal part of right angle steel plate I are connected by bolt I with steel plate；The horizontal part of the steel plate end and right angle steel plate I is equal
