Embodiment 1

[0024] Figure 1-2 A schematic structural diagram of the high-voltage incoming line cabinet according to the embodiment of the present invention is given schematically, as shown in Figure 1-2 As shown, the high-voltage incoming line cabinet includes:

[0025] a circuit breaker chamber having a rear side wall, a left side wall, and a right side wall;

[0026] a first contact group and a second contact group, the second contact group and the first contact group are arranged on the rear side wall from top to bottom;

[0027] a cabinet door having an operating hole;

[0028] The carrier is fixed on the cabinet door; the carrier has a first wing and a second wing arranged from left to right, and the operation hole, the second wing and the first wing are arranged in sequence; the The first wing and the second wing respectively have a through hole, and the distance between the central axis of the through hole and the central axis of the operation hole is smaller than the radius o...

Embodiment 2

[0067] Application examples of the high-voltage incoming cabinet and its working method according to the embodiment of the present invention.

[0068] In this application example, the end of the blocking member away from the protruding portion has an extension portion radially extending along the blocking member. The first wing and the second wing; the first wrench, the handle and the second wrench are set up and down in sequence; the guide is set to convert the rotation of the handle into the forward and backward movement of the blocking piece. When the handle is pushed by an external force such as a handcart, the blocking piece is out of position. , to realize the automatic opening function; under the action of the withdrawal of the handcart and the action of the spring, the blocking member returns to realize the automatic locking function; the left and right sides of the first cover and the second cover have connecting parts, cylindrical The guide rail passes through the co...

Abstract

The invention provides a high-voltage incoming cabinet and a working method thereof. The high-voltage incoming cabinet comprises a cabinet door and a circuit breaker chamber. The cabinet door is provided with an operation hole. The high-voltage incoming cabinet further comprises a bearing member fixed to the cabinet door, wherein the bearing member is provided with a first wing and a second wing from left to right, and the first wing and the second wing are respectively provided with a through hole; a blocking member with the diameter smaller than that of the through hole, wherein the end of the blocking member is provided with a protruding portion, the diameter of the protruding portion is larger than that of the through hole, the blocking member is provided with a padlock hole, and the distance from the padlock hole to the end of the blocking member away from the protruding portion is not less than that from the first wing to the center of the operation hole; a lock passing through the padlock hole. The cabinet has the advantages of simple structure, reliable work and good protection effect.

Description

technical field [0001] The invention relates to a high-voltage wire-entry cabinet, in particular to a high-voltage wire-entry cabinet with a protection function and a working method thereof. Background technique [0002] At present, the basic structure of the high-voltage incoming line cabinet is: cabinet, handcart, and the grounding of the handcart is through the fixed cabinet. When the handcart enters and pulls out of the cabinet, the grounding device of the cart and the grounding of the handcart Device mating, disengagement. When the handcart exits, the high-voltage equipment in the high-voltage incoming cabinet is exposed, and the operator is easy to touch it by mistake, which may cause personal injury. Contents of the invention [0003] In order to solve the shortcomings in the above-mentioned prior art solutions, the present invention provides a high-voltage incoming cabinet with good safety performance and reliable operation. [0004] The purpose of the present in...
