Insulation Accessories, Trolley Switch Cabinet Contact Box

Insulation Accessories and trolley switch cabinet contact box are key components in high-voltage switch cabinets. They play an important role in electrical insulation and safe operation of equipment. The following is a detailed introduction to them:

1. Insulation accessories

Function: Insulation accessories are mainly used to provide electrical insulation, prevent current leakage or short circuit, and withstand mechanical stress and environmental factors.

Material: Common insulation accessories materials include epoxy resin, polyethylene, etc., which have good insulation properties and mechanical strength.

Application: Insulation accessories are widely used in high-voltage switch cabinets, vacuum circuit breakers and other equipment to fix and support conductive parts to ensure the insulation performance of equipment under high-voltage environment.

2. Trolley switch cabinet contact box

Structure: The trolley switch cabinet contact box usually adopts a three-phase integral static contact box design, and the current transformer and the lower static contact are cast in an insulating block to improve insulation strength and safety reliability.

Function: The contact box is used to connect the moving contact and the static contact to ensure the smooth transmission of current. During the movement of the trolley, the protective valve of the contact box can be automatically opened or closed to prevent the operator from touching the live body. Features: The contact box has high measurement and protection accuracy, can meet the requirements of short-circuit dynamic and thermal stability of the system, and has a fully insulated design to ensure the safe operation of the equipment. 3. The relationship between the two Synergy: Insulation accessories and contact boxes work together in high-voltage switchgear. Insulation accessories provide electrical insulation and mechanical support, while contact boxes ensure stable current transmission and operational safety. Importance: The quality and performance of both directly affect the safety and reliability of high-voltage switchgear, so they need to be strictly controlled during the design and manufacturing process. From the above analysis, it can be seen that insulation accessories and trolley switch cabinet contact boxes play a vital role in high-voltage switchgear to ensure the safe operation of equipment in complex environments.
