Description

Anti-mistaken opening 10kV high-voltage switchgear rear cabinet door sealing plate new type locking baffle

technical field

The utility model relates to the field of electrical equipment, in particular to a new type of locking baffle for preventing false opening of a rear cabinet door sealing plate of a 10kV high-voltage switch cabinet.

Background technique

At present, most of the 10kV switchgears operated by power supply companies adopt metal-enclosed switchgears, except for the 10kV feeder switchgear of the KYN trolley cabinet, which has the mechanical interlock function of the grounding knife switch and the rear cabinet door, that is, it can only be used when the grounding knife switch is closed. , to open the rear cabinet door. The rear cabinet doors of the other switch cabinets are only fixed with hexagonal bolts. Into the live equipment interval, there is a great potential safety hazard.

At present, there have been many fatal accidents due to accidental opening of the main transformer 10kV side switchgear and the rear cabinet door of the 10kV bus section switchgear. Because the rear cabinet door of the switch cabinet needs to be opened but cannot be welded dead during maintenance, so in order to meet the safety and work requirements at the same time, and prevent personal electric shock accidents due to the accidental opening of the rear cabinet door of the switch cabinet, it is necessary to develop a The cabinet door is anti-mislocking and does not affect the equipment maintenance.

Utility model content

The technical problem to be solved by this utility model is to provide a new type of locking baffle for preventing the false opening of the rear cabinet door sealing plate of the 10kV high-voltage switchgear, so as to realize the function of preventing the false locking of the rear cabinet door of the high-voltage switchgear, improve the safety performance of the high-voltage switchgear, and prevent the Personal electric shock accident caused by mistakenly opening the rear cabinet door of the switch cabinet.

In order to achieve the above purpose, the utility model provides the following technical solutions: a new type of locking baffle for preventing accidental opening of the rear cabinet door sealing plate of the 10kV high-voltage switch cabinet, characterized in that: the anti-mis-opening 10kV high-voltage switch cabinet The new locking baffle includes an "L"-shaped fixed support frame. The fixed support frame is connected with a movable bending type movable baffle through double hinges. There are lock holes on the upper part of the fixed support frame and the movable baffle, and the fixed support frame Bottom plate holes are arranged at the bottom, and bolts are arranged in the bottom plate holes.

Preferably, both the fixed support frame and the movable baffle are made of carbon structural steel.

After the switch cabinet is unscrewed, the original hexagon socket bolt on the cabinet door fixes and presses the fixed support frame, and a movable baffle is set on the opposite side of the socket bolt. To completely cover or expose the hexagon socket bolt socket, set a lock hole between the fixed support frame and the movable baffle, hang the electric anti-mislock on the lock hole, and set it with the high-voltage switch and the knife gates on both sides The logical locking relationship realizes the function of preventing the rear cabinet door from being opened by mistake.

The beneficial effect of adopting the above technical scheme is: the new locking baffle plate of the rear cabinet door sealing plate of the anti-mis-opening 10kV high-voltage switchgear is installed on any bolt on the electrical equipment cabinet door with a new type of locking baffle and an anti-mistake padlock. The principle of electrical five-proof locking realizes the function of preventing accidental opening of cabinet doors and has a wide range of applications. At the same time, it can also be promoted and applied to solve the problem of accidentally opening live equipment cabinet doors in the current distribution network, which can effectively prevent failures such as ring network cabinets and box transformers.

detailed description

A preferred embodiment of a novel locking baffle for preventing false opening of the rear cabinet door sealing plate of the 10kV high-voltage switchgear of the utility model will be described in detail below in conjunction with the accompanying drawings.

Figure 1 shows the specific implementation of a new type of locking baffle for preventing false opening of the rear cabinet door sealing plate of the 10kV high-voltage switchgear of the utility model: the new type of locking baffle for preventing false opening of the rear cabinet door sealing plate of the 10kV high-voltage switchgear includes "L" Shaped fixed support frame 1, the fixed support frame 1 is connected with a movable bending type movable baffle 2 through double hinges 6, the upper part of the fixed support frame 1 and the movable baffle 2 has a lock hole 3, and the bottom of the fixed support frame 1 There are bottom plate holes 4, and the bottom plate holes 4 are equipped with bolts 5

After the switch cabinet is unscrewed, the original hexagon socket bolt on the cabinet door fixes and presses the fixed support frame 1, and a movable baffle 2 is set on the opposite side of the socket bolt, and the movable baffle 2 is connected with the fixed support frame 1 through a hinge 6. By turning over the hinge 6, the hexagon socket bolt socket can be completely covered or exposed. A lock hole 3 is provided between the fixed support frame 1 and the movable baffle plate 2. The electric anti-mislocking lock is hung on the lock hole 3. By setting It has a logical locking relationship with the high-voltage switch and the knife gates on both sides to realize the function of preventing the rear cabinet door from being opened by mistake. Both the fixed support frame 1 and the movable baffle 2 are made of carbon structural steel.

Design the length, width and height of the fixed support frame 1 according to the structure size of the fixed bolts on the rear cabinet door of the switch cabinet; process the fixed support frame 1 into an "L" shape, and leave holes in the bottom plate, the size of the holes matches the diameter of the fixed hexagon socket bolts, vertical The plate is provided with a lock hole 3, and the height requirement coincides with the lock hole 3 of the movable baffle 2.

The double living hinge 2 method is adopted, and the movable bending type right-angle movable baffle 2 is designed according to the size of the fixing bolts of the rear cabinet door of the switch cabinet. A hinge 6 is designed on the right-angle baffle and at the lower end, the lower end is connected to the bottom plate of the fixed support frame 1 by the hinge 6, and the movable baffle 2 is connected by the upper hinge 6, so that the rotating plate can be covered by two hinges 6 Or expose the hexagon socket bolt socket, and realize that the lock hole 3 of the movable baffle 2 can coincide with the lock hole 3 of the fixed support frame 1 at the same time.

Utilize the original hexagon socket bolts on the rear cabinet door of the switchgear to fix it, rotate the upper and lower hinges 6, the movable baffle plate 2 can be completely covered by the socket bolts, and then hang the anti-mislock on the lock hole 3, through setting It has a logical locking relationship with the high-voltage switch and the knife gates on both sides to realize the function of preventing the rear cabinet door from being opened by mistake.

The above are only preferred embodiments of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the present utility model, some deformations and improvements can also be made, and these all belong to this utility model. Protection scope of utility model.
