Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage disconnectors, in particular to an anti-disconnection device for the connection of switch contacts of a high-voltage isolation electric control box. Background Art

[0002] The high-voltage disconnector is an important switching device in the electrical systems of power plants and substations. It needs to be used in conjunction with a high-voltage circuit breaker. Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work and play a role in isolating voltage.

[0003] For example, a kind of anti-disconnection device for the connection of high-voltage disconnector contacts with the publication number of "CN205230918U". Although it solves the problem that the existing anti-disconnection device for the connection of high-voltage disconnector contacts is prone to disconnection of the connection between the main contact and the main contact finger in strong wind weather, affecting normal operation. By setting an anti-disconnection rotation mechanism, the rotating body and the fixed body on the anti-disconnection rotation mechanism can achieve relative rotation to prevent the slippage between the main contact and the main contact finger under the influence of external forces and improve the safety performance. Considering that the existing anti-disconnection device for the connection of high-voltage disconnector contacts needs to adjust the anti-overturning mechanism to prevent slippage, and there is no support point at the lower ends of the main contact and the main contact finger, in the case of being subjected to the pressure from the upper end, it causes the overall collapse, resulting in an increased probability of the contact being disconnected. Summary of the Invention

[0004] The utility model aims to solve the above problems existing in the prior art and provides an anti-disconnection device for the connection of switch contacts of a high-voltage isolation electric control box, so as to achieve a more firm overall support and reduce the probability of the contact being disconnected.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

The upper end of the base is threadedly connected to a first fixing screw, and the outer wall of the first fixing screw is threadedly connected to a support insulator. The outer wall of the base is connected with a reinforcement mechanism.

[0007] Further improvement: The reinforcement mechanism includes a fixed seat. The outer wall of the fixed seat is fixedly connected to the base. The inner wall of the fixed seat abuts against a square block. The upper end of the square block is fixedly connected to a reinforcement frame. The end of the reinforcement frame is fixedly connected to a first semi-circular ring. The inner wall of the first semi-circular ring is threadedly connected to a second fixing screw, and the outer wall of the second fixing screw is threadedly connected to a second semi-circular ring.

[0008] Further improvement: The outer wall of the first semi-circular ring abuts against the support insulator. The upper end of the base is connected with an anti-disconnection mechanism.

[0009] Further improvement: The anti - detachment mechanism includes an L - shaped strip. The lower end of the L - shaped strip is fixedly connected to the base. The end of the L - shaped strip abuts against the support plate. The inner wall of the support plate abuts against the fixed block. The end of the fixed block is fixedly connected to the connecting rod. The end of the connecting rod is fixedly connected to the connecting seat.

[0010] Further improvement: The inner wall of the connecting seat is fixedly connected to the static contact. The inner wall of the static contact abuts against the fixed body. The end of the static contact is fixedly connected to the terminal post.

[0011] Further improvement: The inner wall of the terminal post is fixedly connected to the support insulator.

[0012] The beneficial effect of the present utility model is as follows: In the present utility model, by aligning the connecting rod at the lower end of the fixed seat with the support plate and inserting the fixed block on the connecting rod into the support plate, the fixed seat at the end of the connecting rod plays an effect of restricting and supporting the position of the static contact.
