[0002] High-voltage switchgear refers to the equipment used for switching, controlling or protecting in power generation, transmission, distribution, energy conversion and consumption in power systems. It mainly includes high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear.

[0003] In order to ensure the good safety of the high-voltage switch cabinet during use, the cabinet body needs to be sealed with a door panel. However, most of the existing high-voltage switch cabinets have the door panel connected on one side. Although the door panel of the high-voltage switch cabinet can be connected, the connection effect of the door panel is poor. When in use, the door panel may shake or have gaps, causing dust to enter the high-voltage switch cabinet, causing damage to the electrical components in the high-voltage switch cabinet.

[0010] Furthermore, the adjustment mechanism includes a limiting slide groove, an adjusting member and a limiting slide plate. The limiting slide groove is opened on one side of the outer surface of the high-voltage switch cabinet, and the limiting slide groove is connected to the locking slot. The adjusting member is fixed on one side of the linkage plate, and the adjusting member passes through the interior of the limiting slide groove. The limiting slide plate is symmetrically fixed on the outside of the adjusting member, and the limiting slide plate slides left and right along the interior of the limiting slide groove for adjustment.

[0011] Furthermore, the upper end surface of the linkage plate is evenly provided with limiting sliders, and the cross section of the limiting slider is a trapezoidal structure, and the limiting slider slides left and right along the upper end of the inner wall of the high-voltage switch cabinet for adjustment.

[0012] Furthermore, a reset slider is symmetrically fixed to the lower end surface of the linkage plate, and the cross-section of the reset slider is a "T"-shaped structure. A reset spring is fixed to one side of the reset slider, and the other end of the reset spring is located inside the locking slot.

[0013] Furthermore, the interlocking mechanism includes a linkage gear, a linkage shaft and an interlocking plate. The linkage gear is meshingly connected to the upper end of the rack body, and the left and right ends of the linkage gear are fixed to the locking slot.

[0015] The utility model has the following beneficial effects:

[0016] The utility model can limit the position of the linkage plate by providing a locking groove and a limiting slider, so as to avoid the linkage plate from being offset. When the adjusting member pulls the linkage plate for adjustment, the linkage gear can be driven to rotate through the rack body, so that the angle of the interlocking plate can be adjusted through the linkage shaft, so that it can be engaged with the interlocking shaft on the inner wall of the door panel body, and then the door panel body can be fixed from both sides, which can avoid the door panel body from shaking during use and the generation of gaps, etc., thereby further improving the application range of the high-voltage switch cabinet body.
