Description

technical field

[0001] The invention relates to the field of electrical switches, in particular to a pressure relief device for a high-voltage switch cabinet. Background technique

[0002] In the current power system, the middle-mounted (KYN28-12) AC closed high-voltage switchgear, such as figure 2 , image 3 and Figure 4 As shown, including the cabinet body, a pressure relief cover is installed above the busbar chamber of the cabinet body, and the pressure relief cover is connected with the busbar chamber by plastic screws; the purpose is to prevent any short-circuit fault in the busbar chamber, resulting in a sharp increase in the internal pressure of the busbar chamber. , The pressure relief cover can be flushed open to achieve the purpose of pressure relief inside the cabinet and ensure the safe operation of the high-voltage switchgear. Although this kind of pressure relief device can reduce the pressure in the busbar room in case of failure and ensure the safety of ...

Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0027] Such as figure 1 and figure 2 As shown, the high-voltage switchgear pressure relief device includes a cabinet body 1, and a pressure relief cover 3 is provided above the busbar chamber 2 of the cabinet body 1. The pressure relief cover 3 and the busbar chamber 2 are connected by metal screws 5. The cover 3 is provided with a pressure relief hole 6 .

[0028] A wire mesh 7 is provided below the position where the pressure relief hole 6 is provided on the pressure relief cover 3, and the wire mesh 7 is welded on the pressure relief cover 6; the wire mesh 7 can strengthen the pressure relief at the place where the pressure relief hole 6 is provided The strength of the cover 3 prevents the position of the pressure relief cover 3 at the pressure relief hole 6 from being broken when the...
