Eco-Friendly Outdoor No Sf6 High Voltage Vacuum Circuit Breaker,
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, 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:
The breakers are recently-developed pole-mounted intelligent vacuum circuit breakers of a new generation, which absorb the advanced domestic and foreign technologies adopted by our company, embody the design concept of being "intelligent, energy-saving, environmentally-friendly and maintenance-free" and comply with the actual conditions of power distribution network and the construction requirements of smart grid. These products can be used as switches at the 10kV side of substation and 10kV outgoing line of main transformer as well as pole-mounted switches for power distribution networks. They integrate such functions as measurement, control, protection, communication, fault isolation and network reconfiguration, with high automatic and intelligent degree; they are top choices for equipment of power distribution network automation and miniaturized substations.

Major Technical Parameters are shown below:
Using Environment:
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.
Main Features:
1. Adopt permanent magnetic operation mechanism; less spare parts; low switching power; stable and reliable; no need regular maintenance.
2. Use imported outdoor hydrophobicity epoxy resin as external insulation meterial; light weight; more than 15 years life; no oil and SF6; no environment pollution; impossible gas leak; comply with environment protection requirement
3. Adopt fast algorithm with national patent technology (patent number:ZL200720037710.7) so as to obtain fast breaking capacity of circuit breaker. As a result, it can isolate fault circuit rapidly. Taking the example of 10kV circuit breaker, it needs less than 25ms from inspecting fault to cut fault circuit by separate circuit breaker. It can avoid the problem of override trip effectively.
4. Adopt single phase ground protection system with national patent technology (patent number:ZL201020178325.6). It can realize on-line judgement on the single phase ground fault of small current ground system without adding devices. In the meantime, it releases warning or tripping action according to setting value.
5. Apply the most advanced insert operation system nowadays; adpot double CPU structure, including ARM9 with general processing and system control; and strong DSP with high efficiency processing on multi-missions; and realize high speed data processing, control and communication.
6. It has the function of automatic switching-on which prevents power failure effectively that causes by instantaneous fault. As a result, the power distribution network could also complete fault isolation and power restoration automatically without the cooperation of main station.
7. Convenient operation, either manual switching-on/off operation, or wireless remote operation. The remote distance is more than 50m.
8. Adopt synchronous switching-on/off technology so as to realize synchronous switching-on/off of circuit breaker and restrain over voltage and inrush phenomenon effectively.
9. Built-in voltage; current sensor; extract measurement in high precision without external PT and CT; protect required various electrical features.
10. Flexible communication ways; support GSM short message, GPRS, CDMA general wireless business, optical fiber, twisted-pair, wireless, carrier wave and other communication ways; and support various kinds of communication agreement.
