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.

Embodiment Construction

[0021] The preferred modes of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] see figure 1 and 2 , A fixed protection device for the secondary mechanism of an isolating switch, comprising a secondary mechanism 11 of the isolating switch and a cable 10 placed on both sides of the isolation switch and connected to it.

[0023] The protective device 30 is provided with a through hole 32 that runs through its body and is used for the cable 12 to pass through, and has conical grooves 31 on both sides. The two conical grooves 31 are communicated through the through hole 32. The end extends into the conical groove 31, the secondary mechanism 11 of the isolating switch is connected to a cable 10 and placed in the conical groove 31 on one side, and the cable 12 connected to the secondary mechanism 11 of the isolating switch passes through the through hole 32 and connect to the cable 10 placed on the other side of t...

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 power equipment protection, in particular to a fixed protection device for a secondary mechanism of an isolation switch. Background technique [0002] In the power industry, the secondary mechanism of the isolating switch is usually installed and fixed outdoors and connected to the cable. Because 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 bound 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", which designs a mounting seat on which a protective sleeve for protecting the secondary mechanism of the isolating switch is sealed and installed, and the protective sleeve is installed on the mounting seat. The bottom is provided with a through hole for the secondary mechanism of the...
