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.
XGN Type SF6-Insulated Ring Main Unit switchgear is a new generation of sulfur hexafluoride or vacuum circuit breaker switch as the main switch and the whole cabinet is air-insulated, compact and expandable metal-enclosed switchgear, with simple structure, flexible operation, reliable interlocking device, easy installation and other characteristics. It is used to open and close load current, fault current, control and protection lines and distribution transformers.
It is suitable for three-phase AC 50Hz, 10~35KV distribution automation power system, which is widely used in industrial and civil cable ring network and power supply end engineering.
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. This product adopts high-performance sulfur hexafluoride load switch with SF6 insulating gas and touchable shielded silicone rubber cable connector, which has strong breaking ability of active load and no-load cable current and short-circuit current closing ability.
2. It can be equipped with lightning arrester and ground fault indicator according to user requirements; Each ring connection line in the branch box can be equipped with a load switch or vacuum circuit breaker.
3. Any branch circuit can be freely withdrawn and put into operation, and other ring network loops are not affected. A circuit fuse can also be attached to the load switch.
4. When a branch circuit has a short circuit fault, the fuse on the branch circuit can quickly disconnect the fault circuit, and hit the derailer of the load switch to open it, and the fault circuit is isolated, so as to ensure the continuity of power supply of the non-faulty branch circuit.
5. The door panels and sealing plates around the switchgear are made of 2mm cold-rolled steel plates, which are strong and durable. The cabinet protection level reaches IP3X.
Applications
1. Power plants, power transmitting of middle and small size generators.
2. Distribution of industrial and mine enterprises.
3. Electricity receiving and transmitting of secondary substations.
4. Starting of motors.
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.
