Switch cabinet handcart positioning device and application equipment thereof

Abstract

The invention provides a switch cabinet handcart positioning device, a switch cabinet circuit breaker handcart matched with the handcart positioning device and a switch cabinet assembled on the handcart positioning device. The positioning device comprises a main body; the main body has a strip-shaped structure; a track groove is formed in the middle of the main body in the length direction; and a test position lock hole and a work position lock hole are formed in one side of the track groove at an interval. The switch cabinet circuit breaker handcart comprises a handcart body; positioning plates are respectively arranged on the two sides of the handcart body; and guide pulleys matched with the track groove of the handcart positioning device and elastic locking levers matched with the test position lock hole and the work position lock hole are arranged on the positioning plates. The switch cabinet handcart positioning device has the beneficial effects that a handcart can be accurately guided and transversely limited and can also be stably positioned under different position states; the applied moment generated by electric force can be effectively reduced, and further, the larger electric force can be overcome; and the switch cabinet handcart positioning device can be used for a handcart type switch cabinet of which the short-circuit current reaches 63 kA.

AI Technical Summary

Benefits of technology

This technology allows for precise guided movement along rails on both handsheld mobile devices (handcarts) and stationary power equipment without causing excess strain or damage from current surges caused during faults such as lightning strikes. It also ensures stability when holding an electricity supply source while still allowing easy access to various tools needed at once.

Problems solved by technology

This patented describes different ways that can hold up or securely fix an electricity supply system's load terminal (LQ) on a cartridge used during power transmission. However, due to their design, they may have limitations such as limited use under certain conditions like heavy loads without being able to handle larger currents than usual. Additionally, some LQ systems require more powerful motors compared to other components, making it harder to achieve reliable performance even if only one component fails completely.
