Embodiment 1

[0049] Figure 1-2 Schematically provides a simplified structural diagram of a switchgear using gas isolation in an embodiment of the present invention, as shown in Figure 1-2 As shown, the switchgear includes:

[0050] The switchgear and the operation panel 11 are all prior art in this field, and will not be repeated here.

[0051] The closed container 51 is welded as a thick steel plate, the closed container is arranged on the rear side of the operation panel, and the inside is filled with insulating gas, such as sulfur hexafluoride, and the switchgear is arranged in the closed container;

[0052] A linkage mechanism 32, the operation end 31 of the linkage mechanism is arranged on the operation panel, and the linkage end is connected to the switchgear; the contact between the linkage mechanism and the closed container is kept sealed;

[0053] Sensors 21, 22, such as concentration and pressure sensors, which display the detected parameters of the insulating gas on the cont...

Embodiment 2

[0075] An application example of the switchgear and its working method according to Embodiment 1 of the present invention.

[0076] In this application example, the insulating gas uses sulfur hexafluoride, and its insulation performance is higher than that of air; the sensor uses a pressure sensor and a concentration sensor, and the pressure sensor is arranged on the operation panel and communicated with the inside of the closed container through a pipe; The concentration sensor adopts an electrochemical sensor, which is set on a closed container, and the output concentration is displayed on the reading table on the operation panel. The display can be the digital display of the display or the display of the scale table; the operating part is "T" The longer part is used as a wrench, and the shorter part has a matching part to match the operating end of the linkage mechanism on the operation panel; so that when the matching part matches the operating end, the wrench can be rotate...

Abstract

The invention provides a switchgear employing gas isolation and a work method thereof. The switchgear comprises an operation panel, a switch device, a closed container, a linkage mechanism, and sensors, insulation gas is inflated in the closed container, the switch device is arranged in the closed container, an operation end of the linkage mechanism is arranged on the operation panel, a linkage end of the linkage mechanism is connected to the switch device, and the sensors display detected parameters of the insulation gas on the operation panel. The switchgear and the work method thereof are advantaged by good safety performance and small size.

Description

technical field [0001] The invention relates to a switchgear, in particular to a switchgear adopting gas isolation and its working method. Background technique [0002] At present, the basic structure of the switch cabinet is: cabinet body, handcart, and the grounding of the handcart is through the fixed cabinet body. When the handcart enters and pulls out of the cabinet body, the grounding device of the cart cooperates with the grounding device of the handcart. , separation. When the handcart exits, the high-voltage equipment in the switch cabinet is exposed, and the operator is easy to accidentally touch it, which will cause personal injury. Contents of the invention [0003] In order to solve the above-mentioned shortcomings in the prior art solutions, the present invention provides a gas-isolated switchgear with good safety performance and small volume. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A sw...
