PRODUCT DETAILS
Company Introduction

New Concept Electric Inc. was founded in October 2001, with a rigistered capital of 57 million Yuan. The company now covers an area of 77601 square meters (116 acres), and has a plant area of 20000 square meters. It is a national high-tech enterprise that specializes in the research and development, manufacturing, sales and service of intelligent medium & high voltage switchgear. Also the company is a leading manufacturer for solid insulated switchgear in China.

Certifications shown below:


ZW32-12 Type outdoor AC high voltage vacuum circuit breakers are used in outside distribution system with rated voltage of 12kV and three phase AC frequency 50Hz. It is used for open and close overload current and short-circuit current in electric system. It is adaptable for control and protection functions in substation and industrial and mining enterprises, and also countryside electricity system. It can also be used as seperate switch, and by adding controller, achieve automation in distribution system.

Main Functions:
Protective Function - It will indentify fault current automatically; realize instantaneous current cutoff, time limited current break, regular flow, directional flow, overvoltage, under-voltage, single phase ground protection of small current ground system, and cooling load start and inhibition of open circuit, and other functions.
Measurement Function - Measure three-phase current, three-phase voltage, active power, reactive power, active energy, reactive energy, peak/valley electricity, power factor and frequency, ect.
Controlling Function - It can realize on-site operation and remote control. Meanwhile, achive fault location of circuit, fault isolation automatically, resume power supply for the circuit without fault rapidly by requirement; realize automatic load shedding under low frequency, capacitor automatic cutting, automatic cutting of backup power, and other controlling functions.
Communication Function - It can report fault, operation and controlling information to appointed personnel through wireless public network or special communication network; support various kinds of communication ways and agreement; realize setting parameters modification by handhold PDA. The controller releases the instruction of self-inspection from PDA and feedback the self-inspection information to PDA terminal.
Data Record Function - Record, save and run operation and fault information automatically.
Synchronous Switching On/Off Function - According to the features of load, it searches zero crossing point automatically; adapt itself to the discreteness of switch parameter and impact of environment factors; realize synchronous switching on/off; restrain over voltage of operation and inrush phenomenon effectively, especially suitable for switching capacitor and transformer.
Intelligence Function - It can carry out on-line conprehensive analysis of power network parameters, on-line performance parameter measurement of circuit breaker, and on-line programming; cooperate with the main station pf power distribution automatic system; realize the function of remote control management of switch device, and on-site, remote or hierarchical control type power distribution automation system.
