Secondary Mechanism Fixed Protection Device of Isolating Switch

Abstract

The invention discloses a fixing and protecting apparatus for an isolating switch secondary mechanism, and relates to the technical field of electric power device protection. The fixing and protecting apparatus includes an isolating switch secondary mechanism and cables which are arranged on two sides of the isolating switch secondary mechanism and are connected to the insulating switch secondary mechanism. A protecting apparatus is provided with a through hole which penetrates the main body of the protecting apparatus and is intended for passage of the cables. The two sides of the protecting apparatus are provided with two cone-shaped grooves which are in communication via the through hole. End parts of two cables extend to the cone-shaped grooves. The insulating switch secondary mechanism is connected to one cable and is disposed at the cone-shaped groove on one side. The cable which is connected to the insulating switch secondary mechanism penetrates the through hole and is connected to the cable which is on the other side of the protecting apparatus. The design of the protecting apparatus enables complete isolation of the insulating switch secondary mechanism, thus realizing effective protection of the insulating switch secondary mechanism. The design of a fixing apparatus enables effective fixing of the cables. The design of T-shaped clamping blocks and an anti-skid ring enable the cables to bear a certain force of drawing and pulling without effecting connecting performances of the insulating switch secondary mechanism.

Description

technical field [0001] The invention relates to the technical field of electric equipment protection, in particular to a secondary mechanism fixing protection device for an isolating switch. Background technique [0002] In the electric power industry, the secondary mechanism of the isolating switch is usually installed and fixed outdoors and connected to the cable. Since the secondary mechanism of the isolating switch is generally not protected, it will be eroded by rain and snow, and the safety hazard is great. Therefore, It is necessary to take a protective device to protect it. [0003] Chinese patent CN 203434067 U discloses a "protection device for the secondary mechanism of the isolating switch". It designs a mounting seat, and a protective sleeve for protecting the secondary mechanism of the isolating switch is sealed and installed on the mounting seat. The bottom is provided with a through hole for the secondary mechanism of the isolating switch to pass through, an...

AI Technical Summary

Problems solved by technology

[0004] 1) The fixity is poor. The device only surrounds the secondary mechanism of the isolating switch through the protective sleeve to form a nominal protection. However, when the cable is under the action of external force, the secondary mechanism of the isolating switch will still be torn off

[0005] 2) The protective performance is poor. The device still cannot avoid defects such as weak sealing through the snap-fit ​​structure. After long-term exposure to wind, sun, and heavy rain, it is bound to cause rain and snow to invade and cause damage to the secondary mechanism of the isolating switch.
