Problems solved by technology
[0004] The purpose of the present invention is to solve the above shortcomings and provide a mechanical support principle to install an insulating bracket on the side of the insulator porcelain bottle, and replace the gravity of the insulating porcelain bottle with the support force to solve the inflexible operation of the GW5 type isolating switch and similar types of isolating switches. Insulation brackets for anti-breakage of porcelain bottles for isolating switches that lead to breakage of insulating porcelain bottles and short-circuiting of wires to ground

The invention relates to an electric auxiliary tool, in particular to an insulating support for preventing fracture of a porcelain insulator of an isolating switch. The insulating support comprises three trapezoidal insulating supports, fixtures connected with isolating switch framework channel steel are arranged at the lower ends of the trapezoidal insulating supports, iron guardrails lapped with the porcelain insulator of the isolating switch are arranged at the upper ends of the trapezoidal insulating supports, the trapezoidal insulating supports are correspondingly connected with an insulating support rod obliquely supported on the ground, and the three trapezoidal insulating supports are serially connected through at least one insulating tie rod. Supporting force replaces the gravity of the porcelain insulator, and the insulating support effectively solves the problems of grounded short circuit of a lead and the like caused by stress fracture of the porcelain insulator due to inflexible operation of GW5 isolating switches and similar types of isolating switches. The insulating support has the advantages of convenience in mounting, debugging and transport and flexibility in operation, can ensure safety of operators on site, and can be popularized and applied to protection of the same types of isolating switches.
Description
[0001] technical field [0002] The invention relates to an electric power auxiliary tool, that is, an insulating support for preventing breakage of a porcelain bottle for a disconnector. Background technique [0003] In the prior art, in recent years, with the increase of power grid reconstruction projects, the number of frequent switching operations of equipment has increased. The GW5 disconnector is a double-column horizontal rotary structure. The two insulating posts in each pole rotate 90° reversely with the conductive knife to form a horizontal fracture. The two posts form a V-shaped intersection angle of 50° and are installed on a base. According to the grounding method, it can be divided into: no grounding, single grounding and double grounding. The GW5 type isolating switch belongs to the product of the 1990s. The insulator porcelain bottle is not high-strength porcelain. Due to the long-term operation of the equipment and the increase in the number of switching oper...
