• our company's advanced transformer with high performance, maintenance-free, low loss, high overload capacity;

• high voltage is manufactured with high reliable and easy to operation, SF6 cabinet, GIS combination H.V. round-ring grids cabinet and overload switch.

● Substation inside structure

• High voltage chamber

High voltage chamber is equipped with XGN-12 type H.V. round-ring grid switch cabinet, with "five anti" functions. When install only one cabinet, it is terminal type; two or three, it is round-ring grids type; more than three, it has function of open and shut off, and can measure by shunting into the line. H.V. round-ring grid switch cabinet can install overload switches, fuses, grounding switches, surge arresters, mutual inductor , electric display and meter, watt-hour meter. If one fuse is blown, overload switch will break-brake automatically which can avoid lack-phase working accidents.

• Transformer chamber

Transformer chamber is equipped with dry or oil-immersed transformer, its top has fan which can automatically control temperature, temperature values can be set as desire. You can observe the oil level of oil-immersed transformer through the oil level mark or reflective mirror. And the transformer chamber has net door to avoid entering into uncarefully when observe

• Low voltage chamber

Low voltage chamber can be divided into with corridor type and without corridor type. Chamber inside has meter cabinet, master switch, outlet cabinet, fuse cabinet and contact cabinet(if has two transformers), which has the overall functions of a set of low-voltage switch devices. General, meter cabinet and master switch usually combine as a whole, the upper part is meter and meter box, the middle and lower part is automatic air switch, surge arresters, mutual inductor, fuse cabinet which can do automatic combination compensation of joint phase and branch phase through manual or automatic control. Capacity of capacitive reactive power compensation is generally 15 to 20% of that of the transformer, also can add or reduce capacity according to customers' requirement.

Notes: 1, more than 1000kVA, determine according to H.V and L.V outlet loops

2, Y is low voltage chamber without corridor, Z is low voltage chamber with corridor

3, this size uses 6-8 loops of L.V. outlet as example

4, length (A,C) of high voltage chamber with corridor need be added 700-800mm

Installation and Maintenance

● Combination(box-type) transformer substation, when you receive it, pls check whether it is damaged during the transportation, if you find somewhere is damaged, you must inform relevant departments to check the reason; if the product will not be installed immediately,  you should put it on a suitable place where need meet the conditions of normal operation.

● Installation of combination(box-type) substation should be based on the scheme of ordering and supplier's installation diagram; prepare the appropriate installed base and materials by users themselves; prepare grounding grids at the surrounding of base, grounding resistance not more than 4Ω.

● Lift the substation on the base, straighten and level, seal the gap between the substation and base by cement, and finally connect the cable.

● After complete the installation, you need crop some grass or trees around the substation to reduce sand to be blown into the substation inside, and it need be surrounded by fences.

● When complete the installation and maintenance , it should be examined and tested the following projects before put into operation:

1) check if the main body is complete and if the inside is clean

2) if operational mechanism is flexible, if it has phenomena of being jammed and operating force being too large

3) if connection and disconnection of main electrical equipments are reliable, accurate, flexible and normal

4) if changes and wiring polarity of meter and mutual inductor are correct, if electrical auxiliary joints are accurate and reliable, if setting value meets the requirements, if core of fuse is correct. Wiring of the main circuit and auxiliary circuit if meets the requirements of electrical schematics.

5) If all electrical installation bolts, nuts are tightened, electrical installations are secure, and whether it is damaged

6)guarantee resistance of all grounding system( main grounding points of every chamber and grounding conductor)  is less than 1Ω

7) every department should carry out pressure experiments according to relevant voltage level

between H.V chambers, voltage to earth is usually 42kV

transformer H.V to L.V, high voltage to earth is 28kV; low voltage is 3kV

between L.V chambers, voltage to earth is usually 2.5kV

voltage to earth of secondary-loop is 2kV

time of all above experiments are one minute.

8) use 500kV megger to meter low voltage loop and secondary loop, insulation resistance should be more than 2MΩ

9) sample the transformer's oil which is on work to analyze once a year; carry out  preventive tests for the arrester before thunderstorm season comes every year. Check the contact of overload switchgears every year and timely repair if has problems. Overload switchgear trips once , need timely repair contacting conditions of contacts. When the overload switchgear trips, firstly find out the reason, then can close after troubleshooting.

● Combination(box-type) substation must be operated and maintained by those qualified persons who have passed professional exanimations or who are approved according to prescribed procedures.

● Factory list of combination(box-type) substation

1) packing list

2) certificate of quality

3) introduction of product

4) electrical schematics, secondary wiring diagram and the installation base diagram

5) key of substation door and spare parts which are promised in the agreement
