Abstract

The invention discloses a novel inflatable switch cabinet which comprises a cabinet body. A gas tank is arranged on the rear side of the cabinet body, a control chamber is arranged on the upper portion of the front side of the cabinet body, a cable chamber is arranged on the lower portion of the front side of the cabinet body, a vacuum breaker is arranged on the upper portion of the gas tank, an isolating switch is arranged in the middle of the gas tank, a main loop is arranged on the lower portion of the gas tank, and an isolating switch operating mechanism and a vacuum breaker operating mechanism are arranged in the control chamber. The isolating switch operating mechanism achieves switch-on, switch-off and ground connection of a disconnecting link by operating a first operating shaft and a second operating shaft, and power-driven operation can be achieved. The vacuum breaker comprises an insulation support, a vacuum bubble and an operating main shaft, the vacuum bubble is arranged in the insulation support in the mode with an upward dynamic contact, a conductive contact and a conductive piece are fixedly arranged on the lower portion of the insulation support and are fixedly connected with a static contact at the lower end of the vacuum bubble, the conductive contact and the disconnecting link are matched for switch-on, and the operating main shaft drives the dynamic contact at the upper end of the vacuum bubble to vertically move to achieve switch-on and switch-off of the vacuum breaker. The novel inflatable switch cabinet is compact in structure, reliable in motion, safe in use and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of switchgear manufacturing, in particular to a novel inflatable switchgear. Background technique [0002] The switchgear is a kind of electrical equipment. The main function of the switchgear is to open and close, control and protect the electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. Whether the operation of the existing switchgear is reliable, the insulation level, whether the volume is miniaturized, the size of the flow capacity, and the maintenance performance are important technical indicators. The reliability of the operation and the insulation level directly affect the safety performance of the switchgear. It affects the installation, floor area and scope of application of the switchgear. The size of the flow capacity directly determines the working capacity of the switchgear, and the quality of maintenance performance dir...
