Description

Technical field [0001] The present invention belongs to the field of distribution charging, and is specifically involved in a complete set of devices and its working methods thereof. Background technique [0002] The statement of this section is merely the background technology information associated with the present invention, which is not necessarily constituted in prior art. [0003] The application of the arc switch in the distribution line belt is very extensive, and the distribution safety procedures are clearly required. When the airborne cable capacitance current is greater than 0.1A, the 10kV charge operation should be operated with an arc switch. With the electricity and off, the airborne line is the highest-to-range charging operation project. The main method of work is: When the capacitor current is not more than 0.1a, the direct arc or insulated operating lever clamp lead quickly departs from the main line, and the air is utilized Gap arc. When the capacitor current ...

Problems solved by technology

When the wind blows or the operator moves the insulating bucket, it is easy to touch the drain wire. The swing of the drain wire drives the swing of the arc suppression switch. The swing of the arc suppression switch will produce relative movement with the wire in the groove of the conductive end cover, reducing the flow of the arc suppression switch. capacity, increasing the hazards of the operation

During on-site operation, the overhead main wire is mostly made of aluminum, and the conductive rod and conductive end cover on the arc suppression switch are made of copper. The contact between copper and aluminum has a large contact resistance, which reduces the flow capacity of the bypass line. The reduction of flow capacity will cause severe heat at the contact point, and in severe cases, it will damage the equipment and cause arc short circuit, which will bring great safety hazards to the operators.

[0004] At the same time, the arc suppression switch has a rated current. If it is overloaded for a long time during work, it will cause damage to the arc suppression switch. It is extremely important to carry out work tasks safely, but currently there is no real-time monitoring device for the flow of the arc suppression switch. The drain wire of the arc suppression switch is measured by current. This method of manual timing measurement can neither achieve real-time measurement, but also increases the labor intensity of live workers.
