Preferably, a blower is installed inside the heat dissipation cabinet.

Preferably, the inner wall of the cabinet is inlaid with reinforcing ribs.

Preferably, the automatic lock is in the shape of a circular groove.

Preferably, the twist angle of the valve is 0-30°.

Compared with the prior art, the beneficial effect of the utility model is: the structure of the low-voltage switchgear is simple and novel, and a dustproof cover is installed at the bottom of the cabinet, which effectively avoids the excessive accumulation of dust, and the cooling cabinet The design makes it possible to effectively control the temperature during work, and the cabinet door adopts a pull-out structure to separate the space in the cabinet, so that the distribution of lines is more reasonable, and the practicability of the low-voltage switch cabinet is greatly improved.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a low-voltage switch cabinet, including a cabinet body 1, a dust cover 2, a busbar room 3, a valve 4, a cabinet door 5, an automatic lock 6, and a heat dissipation port 7 , cooling cabinet 8, temperature sensing device 9, cable inlet 10, cable outlet 11, cable chamber 12, vacuum circuit breaker 13, circuit breaker chamber 14 and rollers 15, the inner wall of cabinet 1 is inlaid with reinforcing ribs, the top of cabinet 1 The dust cover 2 is installed, and the front of the cabinet body 1 is provided with a busbar chamber 3, the outer wall of the busbar chamber 3 is inlaid with a valve 4, the twisting angle of the valve 4 is 0-30°, and the bottom side of the busbar chamber 3 is fixed with Cabinet door 5, the bottom right of cabinet body 1 is provided with automatic lock 6, and automatic lock 6 is circular groove shape, and the bottom end of its cabinet body 1 is installed with cooling cabinet 8, and the inner side of cooling cabinet 8 is installed with blower, and heat dissipation The outer wall of the cabinet 8 is provided with a heat dissipation port 7, a temperature sensing device 9 is arranged on the top side of the cabinet body 1, and a cable chamber 12 is fixed on the bottom side of the temperature sensing device 9, and a cable inlet 10 is arranged on the top side of the cable chamber 12, and the cable A cable outlet 11 is installed at the bottom of the inlet 10, a circuit breaker chamber 14 is arranged at the right end of the cable chamber 12, and a vacuum circuit breaker 13 is embedded inside the circuit breaker chamber 14, and a roller 15 is provided at the bottom of the circuit breaker chamber 14.
