Description

1.Brief Introduction

XGN15-12(L)/T630-25 0r XGN15-12(L . R)/T100-31.5 Cubicle fixed AC metal enclosed switchgear is mainly used for looped network power supply or biradial power supply of electric power system with 3-phase ,AC 50Hz and rated voltage 10KV. It also can be used for terminal power supply as the control device of electric energy and protection device of utilization equipment. More over, it also can be suitable for this switchgear
to be installed in the box substation, especially compact box substation.

2.Service Environmental Condition
Altitude: .< lOOOm
Ambient temperature: -25aC ~ +400C
Relative humidity: The daily average value is not more than 95% and the monthly mean value is not more than 90%.
The surrounding air shall not be polluted by corrosive gas and flammable gas as well as water vapor and so on obviously.
. No location of recurrent strenuous vibration

3.Main structure of switch cabinet
It consists of such parts as bus compartment, 3-position load switch compartment (or circuit breaker compartment), cable compartment, actuator, interlocking mechanism and low-voltage control room as well as measuring circuit or metering circuit and so on. Every compartment is separated by the steel plate so that the fault part avoids affecting the adjacent compartment. It conforms to the GB3906 and IEC298 standard and so on.

. Bus compartment
The bus compartment is arranged on the upper part of cabinet body. The main buses are connected together in the bus compartment and they passes through the whole array of switch cabinet. The arrangement of bus is horizontal and it can be spread out conveniently.

. Load switch compartment
There is a 3-position load switch installed in the switch compartment. The casing of load switch is poured by the epoxy resin. The Sf6 gas is refilled as the arc-extinguishing and insulating medium in the compartment. There are 2 transparent plastic end cover by means of thermal forming installed at the leading end of operating shaft. The contact state can be observed through it. The SF6 gas density gauge or gas density apparatus with alarm contact is installed in the switch compartment according to the client requirement.

. Cable compartment
The cable compartment is mainly used for cable connection. For the connection of single-core cable, the simplest non-shielded cable head is used. At same time, there are such elements as lightning arrester, current transformer and lower grounding switch and so on also can be contained in the enough room. There are observation window and safety interlocking device in the cabinet door as per the standard design. The back plate in the cable compartment is equipped with the sealing cover and appropriate size of cable clamp with support. The frame in front of door at the back plate in the cable compartment can be dismounted for easy cable installation.

. Operating mechanism , interlocking mechanism and low-voltage control room
The low-voltage room with interlocking functions as the screen control at same time. The low-voltage room is equipped with the spring actuator with position indicator and mechanical interlocking device. The auxiliary contact, tripping coil, emergency tripping mechanism, capacitor-type charged display device, key lock and electrical operation device are installed in the low-voltage room. At same time, the control circuit and metering instrument as well as protection relay also can be installed in the spacing of low-voltage room.
There are 2 same low-voltage rooms installed in the 750mm wide cabinet and more accessories can be installed in this size of cabinet.
