Audited Supplier Qinghao Electric is developing and producing a variety series LV MV and HV switchgears including below: KYN, XGN, HXGN, XGW, DFW, GGD, GCK, GBD, PGL MNS and so on.
XGW Ring Main Unit Switch Cabinet is also known as outdoor box type opening and closing station, is composed of load switch cabinet or circuit breaker cabinet, primary and secondary electrical components and box. It can also be combined with power PT, distributed power module, DTU, and communication control terminal to realize distribution automation with compact and scalable power distribution equipment, which greatly improves the reliability of the urban power supply and distribution network.
All high-voltage live parts are enclosed in cold-rolled steel plates or stainless-steel boxes, which can be freely combined with different modules according to the different needs of users to meet the requirements of different power supply schemes and distribution network automation upgrades; It is suitable for three-phase AC 50Hz, 10~35KV power distribution network as the reception, distribution, transfer and line and equipment protection of electric energy.
Main Characteristics
Qinghao switchgear meets the requirements of GB/T11022, GB/T3906 and IEC60298 related standards. It has the interlocking device function to prevent below:
1. pushing and pulling circuit breaker truck when on loading.
2. miss opening and closing circuit breakers.
3. closing the circuit breaker when the grounding switch is in the closed position.
4. miss entry into the live compartment,
5. miss closing the grounding switch when it is live.
Advantages
1. The busbar, switch and live parts are completely enclosed in the stainless-steel gas box, the protection level reaches IP67, and the entire switching device is not affected by the external environment to achieve full insulation and full sealing.
2. It has the functions of full insulation, full sealing, dustproof, corrosion resistance, maintenance-free and so on.
3. It has obvious visual disconnection point, and the function of "five-proof" interlock device, safe and reliable operation.
4. Expandable: It can adopt single-box type, or it can realize multi-channel unit common box, and freely combine various module units to meet different customer needs.
5. Intelligent integration: It can be used with the distribution automation terminal (DTU) to realize telemetry, remote signaling, and remote-control functions to meet the requirements of distribution network automation upgrade.
6. The box material has a variety of options such as cold-rolled steel plate and stainless steel, and the material thickness is 2mm, and the box protection level reaches IP43.
Applications
1. Special places with automatic switching of dual power supply, power distribution in urban residential areas.
2. Small secondary substations, opening and closing stations, industrial and mining enterprises.
3. Shopping malls, airports, subways, wind power plants, hospitals, stadiums, railways, tunnels, etc.
Service Environment
1. Ambient temperature: -30°C to +45°C
2. Altitude: ≤1000 meters.
3. Max. air relative humidity90%(±25ºC);
4. Max. Ground ramp degree 3°;
5. The earthquake: the horizontal acceleration≤0.3m/s2 , the vertical acceleration≤0.15m/s2
6. The installation site shall be free from explosion danger, fire, filthy material, chemical corrosion and violent vibration;
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
Safe and reliable control protection and monitoring function.
*We offer a variety of standard designs and configurations, and also can customize for special designs and options.
