China Wholesale Electric Switchgear Suppliers – XGN15-12 AC Metal-enclosed switchgear – Timetric Detail:

General

Sulfur hexafluoride switch is the master switch of AC Metal-encdlosed switchgear of XGN15-12.The swichgear is air insulated and suitable for distribution automation. It is compact and extensible with simple structure, flexible operation, relible operation and easy installtion. It can be used in different places and meet the requirements of different users.

It adopts sensor technology, latest microcomputer protection, advanced technical function and flexible assembly plan. All of these make it meet the changing demands of the market.

The master switch could be FLN36 type and FLN48 type, SF6 load switch and ABB original SFG type.We could also use ABB original VD4/S, HD4/S and VSI circuit breaker according to the users’ demand.

Working condition

● Aliude: ≤1000m

● The surrounding air is free from corrosive gas and water vapour.

● Ambient temperature: -15℃-+40℃

● Not applicable in the place with frequent violent vibrations.

● Relative humidity: Daily average ≤ 95%;monthly average relative humidity ≤ 90%

Structural feature

lt consists of bus-bar compartment, oad switch with three working positions or circuit breaker compartment, cable compartment, operation mechanism, interlocking device, low voltage control compartment, measuring or counter circuit and so on. Every compartment is separated by steel plate to avoid the influence of fault part.

lt complies with technical requirements of GB3906/IEC298.

● Bus-bar compartment

lt is in the upper portion of the swiltchgear.In this compartment, the main bus-bar connects together, which is horizontal layout for easy stretch

● Load switch compartment

In the switchgear, there is a load switch with two or three working position. The cover of switch is made from epoxy resin. SF6 gas is filled in this compartment as the medium for arc extinction and insulation. Two transparent plastic covers by hot pressing are placed in the ouflet of the shaft. From these covers, we could see the state of contact. SF6 aas density meter can be set up agccordina to the customer’ demand.

● Cable compartment

This compartment is used for cable connection to connect one-core cable with the simplest unshielded cable head. There is also surge arrester, current fransformer, earthing switch and many other components in this enough space. According to the standard of switchgear observation window and safety interlock are installed on the panel. There is sealed cap and cable clamp with support on the baseboard.

● Operation mechanism, interlock device and low voltage controller

The low voltage compartment with interlocking device can also be used as control panel. There is spring operating mechanism with position indicator and mechanical interlocking device in the low voltaae compartment Auxiligry contact. breakina coil emergency trip mechanism, capacitance type live display, lock with keys and electric operation mechanism can be installed in the low voltage compartmen And at the same time, there is still space for control circuit, metering device and protect relay. In the switchgear of 750mm type, there are two same low voltage compariments for more components.
