VCB EVH1 indoor 40.5kV Price High Voltage Vacuum Circuit Breaker
Product Description
Product Description 
Product Overview Overview
EVH1 series vacuum circuit breaker is applicable to three-phase AC system, with rated frequency 50Hz, and rated voltage 12EVH1 series vacuum Circuit Breaker is applicable to three-phase AC system, with rated frequency 50Hz, and rated voltage 12 to 40.5 kV. It can be used for protection and control of mining industries, enterprises, and the electrical facilities of power plants and substations. Standards:GB1984, JB3855 and IEC62271-100 relevant provisions.
Main features:
⚫EVH1 vacuum circuit breaker with GLS01 spring operating mechanism------“Highly integral type mechanism”
* Simple structure, few parts, compact structure, small volume, light weight;
* Complete function, high reliability; operating buttons and state indications are laid out tidily and centrally;
* Easy maintenance:
* During maintenance, you can not only replace the whole mechanism, but also replace the parts on the circuit breaker.
⚫Miniaturized vacuum arc-extinguishing chamber
* Low chopping current value, small contact resistance
* Long mechanical and electrical life, and the contact wear is low during life cycle.
⚫Enclosed main circuit
* The vacuum arc-extinguishing chamber is enclosed in the insulating cylinder vertically, which can prevent the vacuum
arc-extinguishing chamber from damaging because of external factors;
* The flexible filling material can reduce the influence of circuit breaker operating vibration on vacuum arc-extinguishing
chamber;
* Effectively block the external surface creepage of vacuum arc-extinguishing chamber, and reduce the volume.
⚫Excellent coordination of operating mechanism and vacuum arc-extinguishing chamber
* The match of operating mechanism and vacuum arc-extinguishing chamber is calculated by the PRO - E dynamics analysis;
* Through test verification, the contact is with minimal loss under the match;
* Adopt imported adjustable variable damping buffer as opening buffer
⚫Compact structure design
Fewer circuit breaker parts, reasonable and compact structure layout
⚫Wide range of application
The circuit breaker can apply KYN28, KYN79 and other removable switchgears, and also can be fixed installation. Main Technical Parameters
