Product feature

HW-XG series fixed AC metal enclosed switchgear (short for panel as below) is a new product designed and developed by YUANKY, based on the introduction of advanced foreign design and manufacturing technology. It applies to 3.6~ 12kV three phase AC 50Hz single busbar or single busbar sectional transport, transmission & distribution system, as for receiving and distributing power energy, and realize to control, monitor and protect power circuit. It is widely used for power plant, substation, petroleum, metallurgy, chemical, natural gas and other civil field. Structure feature:

1. HW-XG series is metal enclosed fixed switchgear, the body is welded with angle steel and steel board, inner and outer coating is solid by static spray plastic powder.

2. This panel conforms to GB3906 3-35kV AC Metal enclosed switchgear and international standard IEC62271-200 besid es, prevent from opening and closing conne cting swit ch with lo ad, prevent from opening and closing C ircui t bre aker, prevent from entering into interval with electricity, prevent from closing earthing switch with electricity (five protections adopt simple, reliable mechanical interlock device). The power indicator is installed in front of panel which reflect voltage in the side of circuit. When circuit side with electricity, lock the enclosed board and panel door.

3. Same type product and structure component can exchange each other.

4. Enclosure

♦ The inner structure of panel is divided into circuit breaker compartment, busbar compartment, cable compartment , relay compartment, use steel plate to separate panels. Use eddy current steel plate and ep oxy resin busbar bushin g to sepa rate panel.
♦ The panel adopts cold roll steel sheet and angle steel to weld together, without reticulation fabric, non-flame-resisting materials. Outer insulating creeping distance of components and supporting insulator, pure porcelain insulation ≥1 .8cm/kV, organic insulation ≥2 .0cm/kV. The air distance of phase to phase, phase to earth≥125mm. There is an intelligent hygrothermoscope to start or stop heater according to the humiture condition.f circuit breaker compartmen t and cabl e compartm ent in pan el, Prevent from forming moist and high temperature.
♦ There is a viewing port for observing of closed and open position of upper, down C onnecting switch without open the do or. The panel isdouble maintenance, inspect relay compartment equipments, operating mechanism, mechan ical i nterlock and transmission part in front,
