Features & Construction
- This switchgear is a metal enclosed box structure, and the cabinet body is made of cold-rolled steel plates and angle steel welded together.
- The color of the cabinet body is specified by the user. Made of useless mesh textiles and non refractory materials.
- The external insulation creepage distance of each component and supporting insulation in the high-voltage switchgear is ≥ 1.8cm/kV for pure ceramic insulation and ≥ 2.0cm/kV for organic insulation.
- The front of the switchgear is equipped with an observation window, which allows you to observe the on/off positions of the upper and lower isolation switches and circuit breakers without opening the cabinet door.
Product Details
In the power supply system, it is also used for breaking load current, short-circuit current, and closing short-circuit current. This ring main unit is equipped with FN12 and FZRN21 vacuum load switches, and the operating mechanism is a spring mechanism, which can be operated manually or electrically.
The grounding switch and isolation knife are equipped with a manual operating mechanism. This ring main unit has strong completeness, small size, no combustion and explosion hazards, and reliable “five prevention” functions. This ring main unit complies with the relevant provisions of GB3906 “3-35kV AC Gold Group Enclosed Switchgear” 1EC60420 “High Voltage AC Load Switch Fuse Combination Apparatus” standard.
2.Altitude: not exceeding 1000m; Any place with an altitude exceeding 1000m shall be handled in accordance with JB/Z102-72 “Technical Requirements for High Voltage Electrical Appliances Used in High Altitude Areas”.
