Outdoor switch cabinet with automatic counterweight protection function

Abstract

The invention relates to the field of outdoor switch cabinet protection equipment, and particularly relates to an outdoor switch cabinet with an automatic counterweight protection function. The cabinet comprises a switch cabinet main body and a fixed base. Anti-collision devices are movably installed on the left side and the right side of the outer end of the switch cabinet main body, buffer rotary drums are movably installed on the inner sides of the anti-collision devices, and counterweight blocks are movably installed on the two sides of the upper end in the switch cabinet main body. A limiting device is movably installed at the lower end in the switch cabinet main body, the guide plate is fixedly installed on the outer side, opposite to each buffer rotary drum, of each anti-collision device, the guide plate is arranged in a trapezoidal shape with the two inclined sides, and therefore when the outer side of the switch cabinet main body is impacted by a small impact object, the impact object can make contact with each buffer rotary drum; and then the impact object is guided to two sides under the action of the outer side arc surface of each buffer rotary drum, and the impact object can move away from the switch cabinet main body under the action of the inclined surface of the guide plate so that the impact object is prevented from completely acting kinetic energy on the switch cabinet main body, and the protection effect of the switch cabinet main body on the external impact is improved.

Description

technical field [0001] The invention relates to the field of protection equipment for outdoor switch cabinets, in particular to an outdoor switch cabinet with automatic counterweight protection. Background technique [0002] The main function of the power distribution switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protection devices. The power distribution switchgear is divided into power distribution cabinets, lighting distribution cabinets and metering cabinets. The final equipment of the electrical system, the power distribution switchgear is the collective name of the motor control center.

Problems solved by technology

[0003] The current switch cabinets are often installed outdoors because they need to meet the needs of different locations, but most of the existing switch cabinets lack guidance and avoidance structures for external impacts, so that all the forces generated by external impacts will act on the switch cabinets, resulting in While the damage and leakage of the switchgear cause secondary damage, it also increases the difficulty of subsequent repairs
