Embodiment Construction
[0031] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0032] The specific embodiment of the control cabinet of GIS equipment of the present invention, as figure 1 As shown, the control cabinet of the GIS equipment includes a cabinet body 1, and a controller is arranged in the cabinet body 1, and the controller is used to control the opening and closing of the heating device on the GIS shell. Cabinet body 1 top is provided with anti-rain eaves 2, and anti-rain eaves 2 is provided with ventilation hole 21 and groove, and ventilation hole 21 is arranged on the front side of cabinet body 1, and groove is arranged on the left side of cabinet body 1. In this embodiment, the groove is a U-shaped groove with the opening facing downwards. The left-right direction of the cabinet body 1 is the horizontal direction, and the front-to-back direction of the cabinet body 1 is the longitudinal direction. The U-shaped groove...

The invention relates to a control cubicle of GIS equipment and the GIS equipment by using the same. The control cubicle of the GIS equipment comprises a cubicle body, a controller is arranged in thecubicle body, and the controller is used for controlling the on-off of a heating device on a GIS shell; the cabinet body is also provided with a temperature sensor which is exposed to the outer side of the cabinet body and is used for detecting the temperature of an external environment. The temperature sensor is in signal connection with the controller through a signal line; and a heat insulationstructure is arranged between the temperature sensor and the cabinet body. The controller is arranged in the cabinet body; the temperature sensor is arranged on the cabinet body; the distance betweenthe temperature sensor and the controller is greatly shortened; the controller can accurately obtain a detection temperature signal of the temperature sensor, in addition, the heat insulation structure separates the temperature sensor from the cabinet body, heat in the cabinet body can be prevented from being transmitted to the temperature sensor, and therefore when the external environment temperature reaches the starting temperature of the controller, the controller can accurately start and control the heating device to heat the GIS shell.
Description
technical field [0001] The invention relates to a centralized control cabinet of GIS equipment and GIS equipment using the centralized control cabinet. Background technique [0002] In UHV transmission channels, many GIS substations have sprung up in cold energy bases such as the west and the north, and the outdoor ambient temperature in these areas is relatively low in winter, dropping to -40°C, and even reaching -50°C in some areas. Sulfur fluoride gas will liquefy at this temperature, causing the circuit breaker to fail to work reliably, resulting in equipment damage or more serious accidents. In the face of the problem of liquefaction of sulfur hexafluoride at low temperatures, it is often necessary to install a heating device on the GIS shell to increase the temperature of sulfur hexafluoride to avoid liquefaction. For example, the application publication number is CN107864525A, and the application publication date is 2018.03.30 Chinese invention patent In the heating ...
