Problems solved by technology

[0002] The operating mechanism of the existing switchgear is exposed in the air. There are many moving parts composed of electroplated parts (metal parts) in the operating mechanism, and the moving parts will be coated with lubricating grease; Under the influence of salt, harmful gases, etc., the electroplated parts are easy to rust, and the grease is easy to dry up, causing the movement of moving parts to be blocked, resulting in mechanism failure and abnormal operation of switchgear

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as Figure 1-2 As shown, a switchgear operating mechanism integrated gas box includes a gas box 1, a control line socket flange 2 is arranged on the top of the gas box 1, and a direct-acting interface flange 3 is arranged on the side wall of the gas box 1. The rotating interface flange 4, the observation window flange 5 and the air pipe seat 6 with a one-way valve; the direct-acting interface flange 3 and the rotating interface flange 4 are arranged on the back of the air box 1, and are distributed up and down; The observation window flange 5 and the air pipe seat 6 are arranged on the front of the air box 1, distributed up and down; a pressure gauge is installed on the air pipe seat to intuitively understand the air pressure change inside the air box 1.

[0018] Nitrogen or dry air is flushed into the gas box 1, and various flang...

Abstract

The invention relates to a switchgear operating mechanism-integrated gas box, which comprises a gas box. A plurality of switchgear operating mechanisms are integrated in the gas box; the switchgear operating mechanisms are connected with other mechanisms through connection flanges; and an insulating gas is fed to the gas box. Through integrating the switchgear operating mechanisms in the inflatable gas box, influences on the switchgear operating mechanisms by the environment can be eliminated completely, and actions of the operating mechanisms are ensured to be normal.

Description

technical field [0001] The invention relates to the technical field of switchgear operating mechanisms, and specifically discloses a switchgear operating mechanism integrated gas box. Background technique [0002] The operating mechanism of the existing switchgear is exposed in the air. There are many moving parts composed of electroplated parts (metal parts) in the operating mechanism, and the moving parts will be coated with lubricating grease; Under the influence of salt, harmful gases, etc., the electroplated parts are easy to rust, and the grease is easy to dry up, causing the movement of moving parts to be blocked, resulting in mechanism failure and abnormal operation of switchgear. Contents of the invention [0003] The purpose of the present invention is to solve the above problems by providing an integrated air box for the switchgear operating mechanism that completely eliminates the influence of the environment on the switchgear operating mechanism and ensures th...
