Description

A protective device for outdoor high voltage circuit breaker

Technical Field

The utility model relates to the technical field of circuit breakers, in particular to a protective device for outdoor high-voltage circuit breakers.

Background Art

High-voltage circuit breakers (or high-voltage switches) can not only cut off or close the no-load current and load current in high-voltage circuits, but also play a controlling role in high-voltage circuits and are one of the important electrical components in high-voltage circuits. Existing outdoor high-voltage vacuum circuit breakers do not have heat dissipation and lightning protection functions during use, which can easily affect the equipment by temperature, weather, etc., reducing the service life of outdoor high-voltage vacuum circuit breakers and increasing economic costs. In addition, the fixed installation structure is complex and inconvenient to operate, so it is not convenient to use.

The announcement number is CN216353942U, which discloses a protective device for outdoor high-voltage vacuum circuit breakers, including a protective box and a circuit breaker body. The protective box is provided with supporting legs at the lower end, and an insulating plate is provided inside the protective box. A lightning rod is provided at the upper end of the outer side of the protective box, and a box door is connected to the front of the protective box through a hinge. The circuit breaker body is installed on a fixed limiting mechanism. The protective device for outdoor high-voltage vacuum circuit breakers is provided with mounting holes, insulating plates, ventilation strip holes and lightning rods. The mounting holes can facilitate the installation of the device on an object, improve the stability of the device, and simplify the operation. The insulating plates can prevent workers from touching the protective box and getting electric shocks, thereby improving the protective effect of the device. The ventilation strip holes can facilitate the heat dissipation inside the protective box to prevent the temperature from being too high and affecting the service life of the circuit breaker body. The lightning rod can avoid the impact of lightning on the circuit breaker body on rainy days, thereby improving the practicality of the device.

Although the above scheme improves the protection effect of the circuit breaker when used outdoors, after the circuit breaker body is placed in the mounting groove on the mounting base, the circuit breaker body must be positioned one by one at multiple points in cooperation with screws, vertical plates and clamps. The equipment is cumbersome and laborious to assemble or call the circuit breaker body separately. The dustproof net at the ventilation strip hole is blocked by the circuit breaker body, and the space for personnel to assemble and remove the dustproof net is limited and inconvenient. Moisture in the air will also contact the circuit breaker body to accelerate its damage. For this reason, we propose a protective device for outdoor high-voltage circuit breakers.
