The way of leading in and out for the cabinet is overhead leading-in and leading-out wires, and the bus room is sealed or open.
This product can also achieve bypass power supply and has 5-protection function.
The framework of the cabinet mainly consists of the fore cabinet and rear cabinet, and the fore cabinet consists of breaket, main bus (room), relay, etc.
XGN2-12 fixed metal sealed switching equipment
This equipment (switching cabinet, for short ) is used in systems with 6.10KV, 3-phase AC, 50Hz for power taking and distribution, and it is especially suitable for places with frequent operations. The bus system is single bus. This switching cabinet is a full metallic sealed structure, with the case protection class IPZX. The main switch applies ZN 28A-10 series vaccum breaker, in conjunction with CD10 series electromagnetic and CT8 series spring mechanism. The isolation switch applies GN30-10 rotational isolation switch and GN22-10 large-current isolation series product. It has mechanic 5-prevention interlocking devices which are arranged in a concentrated way.
HXGN-12 looped net vaccum switching cabinet
This switching cabinet (looped net cabinet, for short) is suitable for the power distribution system of industrious and mining enterprises, residential areas, high buildings and schools as indoors looped net power supply unit and terminal power distribution equipment with AC 3-phase 12KV, 50Hz. It can turn on or off nominal load current and transformer no-load current and turn on or off the capacitor current of overhead lines, cable lines of capacitor groups from a distance. The load switch-breaker electric cabinet can one-time turn on or off nominal short-circuit current. It is used for the protection of power distribution equipment and the distribution and control of electric energy in power supply systems.
XGN2-10, GGX □10 indoors high-voltage box-type fixed metal closed switching equipment
This equipment is suitable for systems with 3-10KV, 3-phase AC, 50Hz, for the purpose of power taking and distribution and control and protection monitoring of circuits, and especially suitable for places with frequent operations. Its bus system is a single-bus and single bus sectional structure.
XGN 2-10 switching equipment applies ZN17A-10 series vaccum breaker or SN10-10 series oil lack breaker, in conjunction with CD10 series or CT8 series operation mechanism. The isolation switch applies GN30-10 (D) rotational isolation switch and GN22-10 large-current isolation switch.
GGX□-10 switching equipment applies ZN17A-10 series vaccum breaker, in conjunction with CD10 series or CT8 series operation mechanism. The isolation switch applies GN24-10D isolation switch with grounding switch, GN19-10CI isolation switch and GN25-10 large-current isolation switch.
GG-1AF(Z) high-voltage switching cabinet
This cabinet is suitable for power supply systems with nominal voltage 3-10kv, 3-phase AC, 50Hz, single bus, for the purpose of power taking and distribution.
This switching cabinet is an indoors unit, installed against wall. The cabinet body applies framework structure, divided into separate 3 sections by bus partition and middle partition. The upper section is main bus and bus side isolation switch, the middle section is breaker, while the lower section is the line side isolation switch. The top-left part at the front is relay room, and the bottom part is terminal room. The terminal room is equiped with exciter lamp, with its switch on the door of the terminal room. The breaker, operation mechanism and mechanical interloking for isolation switch are mounted on the panel on the left. Between the upper, middle, lower doors and the operation mechanism is also mounted mechanical interlocking. The locking unit consisting of the above interlocking has 5 erroneous operation functions.
