High-voltage disconnectors are important switchgear in the electrical systems of power plants and substations, and must be used in conjunction with high-voltage circuit breakers. Disconnectors are suitable for indoor installations with three-phase AC 50Hz and a rated voltage of 12KV. They are used to connect, disconnect or convert lines when the high-voltage equipment is under voltage and load. Their main functions are: to ensure the safety of high-voltage electrical appliances and devices during maintenance work, to isolate voltage, and cannot be used to disconnect, put in load current or break short-circuit current. They can only be used for certain switching operations that do not generate strong arcs, that is, they do not have arc extinguishing functions; they are divided into indoor and outdoor types according to the installation location, and into single-column, double-column and three-column types according to the number of insulating pillars. There are optional devices for each voltage level.

In the prior art: CN201520347442.3 Isolating switch bracket, the utility model discloses an isolating switch bracket, which belongs to a bracket, and its structure includes a cross arm, a connecting plate, a washer and a clamp. Three connecting plates are arranged on the front side of the cross arm, and each of the connecting plates is arranged at an angle. Switch connecting holes are arranged at both ends of each connecting plate. Washers and clamps are arranged on the rear side of the cross arm. The washers are M-shaped washer, and the rear end of the washers is an arc surface, which matches the outer circumference of the pole. The clamp passes through the washers and the cross arm and is fixed by a fastening nut.

Although the isolating switch bracket in the prior art has the characteristics of reducing the weight of the bracket, saving materials, reducing the cost, facilitating installation and operation, preventing birds from nesting, and avoiding line failures, and thus has a good value for promotion and application, the switch bracket in the prior art cannot optimize the strength of the middle position well, and the overall strength of the switch bracket is affected.

Utility Model Content

In order to overcome the deficiencies of the prior art, the utility model provides a high-voltage isolating switch bracket.

The utility model is implemented by the following technical scheme: a high-voltage disconnector bracket, comprising a bracket plate, a shelf bar is arranged on the bracket plate, an assembly rod is arranged on the shelf bar, a ceramic insulator is arranged on the assembly rod, an assembly plate is arranged on both sides of the bracket plate, the assembly plate and the bracket plate are welded to each other, mounting bolts are arranged on the assembly plate, an assembly space is arranged in the middle of the bracket plate, a support channel steel is arranged in the assembly space, a positioning component is arranged on the support channel steel, and the positioning component and the assembly rod are connected to each other.

The positioning component is a positioning sleeve, which is directly sleeved on the assembly rod, and a positioning rod is arranged on the outer side of the positioning sleeve.

A positioning vertical rod is arranged at the bottom of the positioning rod, and the positioning vertical rod and the supporting channel steel are connected to each other, and the positioning vertical rod and the supporting channel steel are welded to each other.

The assembly rod is provided with a top cap, a ceramic insulator is installed on the assembly rod, a threaded rod is provided on the top of the ceramic insulator, and the threaded rod and the top cap are threadedly assembled.

Compared with the prior art, the utility model can rely on the assembly rod on the switch bracket to assemble the insulator when in use, so that the assembly of the insulator is more stable. At the same time, an assembly space is provided in the middle of the bracket plate, and a supporting channel steel is provided in the assembly space. The supporting channel steel can be used to well enhance the strength of the middle position of the switch bracket, thereby meeting the use effect of the switch bracket and ensuring the overall use strength of the switch bracket.
