Description

Technical Field

[0001] This utility model belongs to the field of high voltage switchgear manufacturing technology, specifically relating to a tooling for fastening the dynamic seal of an environmentally friendly gas-insulated switchgear. Background Technology

[0002] Environmentally friendly gas-insulated switchgear is an electrical device that houses high-voltage switchgear within a sealed metal chamber filled with environmentally friendly gas at rated pressure, forming an assembled, compartmentalized ring network power supply unit. The core components of this switchgear are load switches and circuit breakers, insulated with environmentally friendly gas, offering advantages such as safe power supply, high reliability, and environmental friendliness. The conductive components, including circuit breakers and load switches, are located within the gas chamber, while the operating mechanisms for these components are located outside. These mechanisms drive dynamic sealing assemblies mounted on the metal plate of the gas chamber, transmitting the action to the load switches and circuit breakers to achieve circuit closing and opening. Common dynamic sealing assemblies consist of a brass flange fixedly connected to the metal plate of the gas chamber, a rotating shaft, and a rotary seal between them.

[0003] In existing technology, one end of the flange seat has a threaded structure. The pressure of tightening the threads deforms the sealing ring, achieving an airtight seal at the contact surface. Three to four evenly distributed grooves are provided on the outer end face of the flange seat, and a mounting block is provided on the flange seat. A hook wrench is used to tighten the flange seat to the metal plate. However, because the metal plate of the air chamber has many welded studs required for installing the operating mechanism, when tightening the brass flange seat with a hook wrench, it is often difficult to rotate the wrench completely due to avoiding the welded studs, resulting in time-consuming and laborious operation and low installation efficiency of the dynamic sealing assembly. Utility Model Content

[0004] This utility model provides a tooling for tightening the dynamic seal of an environmentally friendly gas-insulated switchgear, which aims to solve the problem of low work efficiency caused by interference when tightening flange seats with a hook wrench in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a tooling for fastening the dynamic seal of an environmentally friendly gas-insulated switchgear, comprising: The annular pressure plate has multiple limiting posts at its bottom end, and each limiting post is arranged circumferentially around the axis of the annular pressure plate; each limiting post is used to fit into a groove on the flange seat. A fixing plate is fixed above the annular pressure plate and is coaxially arranged with the annular pressure plate; the fixing plate has a positioning end that extends downward and can correspond to the mounting block; the top of the fixing plate has a clamping part for a wrench to hold.

[0006] In one possible implementation, the annular pressure plate includes: The plate body abuts against the flange seat, and the plate body is provided with a through hole for the dynamic seal to pass through; The fasteners are provided in multiple ways, and each fastener is provided in a one-to-one correspondence with each of the limiting posts. Each fastener is threadedly connected to the corresponding limiting post. The plate body is provided with post holes for each of the limiting posts to pass through.

The adapter is connected to each of the connecting support plates. Wherein, any two adjacent connecting support plates and the plate body enclose an installation space, and each of the limiting posts is located in the installation space.

[0008] In one possible implementation, the adapter includes: An installation rod is provided along the axial direction of the plate body. The installation rod is installed on the auxiliary plate. The upper end of the installation rod extends out of the auxiliary plate, and the lower end of the installation rod is located between the auxiliary plate and the plate body. The lower end of the installation rod is provided with an installation groove for the installation block to be installed. An operating lever is located at the upper end of the mounting rod; the operating lever is the clamping part. The mounting groove is the positioning end.

[0009] In one possible implementation, the auxiliary plate is a circular structure, the plate body is a circular structure, and the diameter of the auxiliary plate is smaller than the diameter of the plate body.

[0010] In one possible implementation, the auxiliary plate is provided with a plurality of weight-reducing holes, and each of the weight-reducing holes is arranged circumferentially around the axis of the auxiliary plate.

The included angle between the connecting part and the supporting part is an obtuse angle.

[0012] The beneficial effects of this utility model on the tooling for fastening the dynamic seal of an environmentally friendly gas-insulated switchgear are as follows: Compared with the prior art, by setting an annular pressure plate with multiple limiting posts at its bottom end, each limiting post is arranged annularly around the axis of the annular pressure plate. Each limiting post is used to fit into a groove on the flange seat, thereby locking and fixing each limiting post in the corresponding groove, while the annular pressure plate abuts against the flange seat. A fixing plate is fixed above the annular pressure plate, coaxially arranged with the annular pressure plate, and located above the metal plate. The fixing plate has a downwardly extending positioning end, which corresponds to the mounting block, thereby aligning the center of the tooling with the center of the dynamic seal.
