Serye ng JN15-12 na Indoor HV Earthing Switch

Pahayag:

Ang grounding switch ay tumutukoy sa isang mekanikal na grounding device na naglalabas ng electrostatic charge ng mga kagamitan na kailangang i-repair at ng circuit at nag-uugnay sa personal na kaligtasan ng mga maintenance personnel habang may power failure. Ito ay maaaring matiis ng isang tiyak na panahon sa ilalim ng hindi normal na kondisyon tulad ng short circuit, ngunit hindi ito lumalampas sa load current sa normal na kondisyon. Karaniwang bahagi ito ng disconnector.

Pang industriyang aplikasyon:

Ito ay angkop para sa mga power system na may AC 50Hz na 12kV at ibaba. Ito ay maaaring gamitin para sa grounding protection habang nangangailangan ng pag-maintenance ng high-voltage electrical equipment, at maaari ring gamitin kasama ng iba't ibang uri ng high-voltage switchgear.

Mga tampok:

• Ambient temperature: -15°C~+40°C.

What are the structural characteristics of indoor high-voltage AC grounding switch?

Contact System:

• Materials: The contact system typically uses high-performance conductive materials such as copper alloys to ensure good conductivity and the ability to withstand high current impacts.

• Design: The shape of the contacts can vary, including knife-type contacts and finger-type contacts, among others. These designs aim to increase the contact area, reduce contact resistance, and minimize heat generation.

Operating Mechanism:

• Manual: Simple and reliable, with lower costs. Suitable for applications where the frequency of operation is low.

• Electric: Enables remote control and automated operations, making it easy to integrate with the monitoring systems of substations.

• Spring-Operated: Combines the advantages of manual and electric mechanisms. It uses pre-stored spring energy to achieve fast and reliable opening and closing operations.

Insulation Section:

• Insulators: Primarily composed of insulators made from materials such as ceramic, glass, or composite materials.

• Ceramic Insulators: High mechanical strength and excellent insulation properties.

• Glass Insulators: Good self-cleaning performance, capable of resisting windblown sand and dirt to some extent.

• Composite Material Insulators: Combine multiple advantages, such as being lightweight and having excellent pollution resistance.
