Mobile armored metal-enclosed switch cabinet

Abstract

The invention relates to a mobile armored metal-enclosed switch cabinet. The mobile armored metal-enclosed switch cabinet effectively achieves intelligent update and real-time monitoring of normal operation of an unattended transformer substation. According to the method, a vacuum circuit breaker is installed in the middle inside a box body, an intelligent switch control device, an intelligent microprocessor protection device and a merging unit are installed at the upper portion of a front door of the box body, an electric chassis and an electric ground switch are installed at the lower portion of the circuit breaker, an upper copper bar and a lower copper bar are installed inside the rear portion of the box body, a smoke sensor is installed inside the top of the box body, an electronic voltage transformer and an infrared temperature sensor are installed in the middle inside the box body, the infrared temperature sensor is connected with a moving contact and fixed contact box, the moving contact and fixed contact box and the electronic voltage transformer are connected with an electronic current transformer through the lower copper bar, and the intelligent microprocessor protection device is connected with the merging unit, the intelligent switch control device, a short circuit fault indicator, the smoke sensor, the infrared temperature sensor, the infrared temperature sensor and the vacuum circuit breaker. The mobile armored metal-enclosed switch cabinet is novel, unique and easy to produce, complete safety protection is achieved, and safe operation of equipment is guaranteed.

Description

technical field [0001] The invention relates to electrical appliances, in particular to an armored removable metal-enclosed switchgear. Background technique [0002] Switchgear is an indispensable complete set of equipment in power supply and distribution, especially with the acceleration of the modernization process, new requirements have been put forward for the intelligent technical transformation of urban networks. According to the requirements of technical transformation, the 40.5kV, 24kV and 12kV switch stations are required to have remote monitoring, unattended, and remote scheduling. However, as the equipment installed in domestic substations today, it cannot meet the country's requirements for intelligent transformation of substations. [0003] The specific performance is: [0004] 1. For the vacuum circuit breaker installed in the existing switchgear, an operator needs to be dispatched every time the power transmission is stopped, and the switch should be turned ...
