Outdoor Prefabricated Compact Substation

Outdoor Prefabricated Compact Substation

Ac metal closed type shift switch cabinet is a three-phase ac 50HZ indoor device metal closed switch equipment.Is used in power plants, substation system rated voltage 35kV, rated maximum current 2000A maximum voltage no more than 40.5kV single bus or single bus sectionalized sets of distribution equipment.

This switch device meets the requirements of DL/ t404-91, IEC298, GB3906 and other standards, and has the functions of preventing wrong operation of circuit breaker, pushing and pulling handcart with load, grounding line, power transmission with grounding line and accidental charging interval (referred to as "five precautions").

Box type substation is suitable for residential district, urban public change, bustling downtown, construction power and so on. Users can choose box type change according to different use conditions and load grade. Since the advent of the box substation, it has developed very rapidly. In developed countries, 70% of the distribution transformers have been developed, and the United States has accounted for 90%. The rapid development of China's urban modernization and the renovation of urban distribution network will be widely applied.environment condition.
Box type substations are used in high-rise residential, luxurious villas, square parks, residential areas, small and medium factories, mines, oil fields, and temporary construction electricity and other places to accept and distribute electricity in the distribution system.

This series of pre-installed substations are suitable for 12kV, three-phase AC systems with a rated frequency of 50Hz, and residential quarters, commercial buildings, hotels, large construction sites, high-rise buildings, industrial and mining enterprises and temporary construction sites with a capacity configuration below 2500kVA. Network power supply is also suitable for radial terminal power supply.

This series of prefabricated substations has the advantages of small size, small footprint, large selectivity, small on-site installation, and short installation and debugging cycle. And features such as moving with the load center.

The European type substation, is a complete set of new power transformer equipment developed by our company on the basis of transformation of national urban network making the optimal combination for the oil-immersed sealed power transformer and high and low voltage electrical components. Through structure optimization, the switchgear shall be miniaturized to extreme extent which greatly reduce the occupied area of the combined transformer with such advantages as small volume, low noise, reliable power supply, reasonable structure, blexible for installation, easy for operation and capable of going deep into the load center to maximum extent, etc.It can assemble network automation terminal (FTU) in the high-voltage ring network cabinet, realize the reliable detection of short circuit and single-phase grounding fault, and has the function of "four remote", which facilitates the automatic upgrade of network distribution. It is widely used in residential quarters commercial centers stations industrial and mining enterprises airports railroads schools hospitals, high-rise buildings and places.

Environmental conditions:

Altitude: 1000m and below.
Ambient temperature: - 25 ~ +40 C.

Wind speed: no more than 35m/s.
Arelative humidity: no more than 90% (+25 C).
Seismic horizontal acceleration: no more than 0.4m/s, vertical acceleration: not greater than 0.2m/s.
Place of use: there should be no conductive, dusty, hazardous, corrosive, inflammable and explosive materials harmful to metals and insulators.

Feature

1. The frame of the substation is made of anticorrosive grooved steel and angle steel, so it is tough enough in terms of machinery and rigidity.

2. The shell material can be cold rolled steel plate, stainless steel plate, aluminum alloy plate, composite color plate.

3. The small rooms of the substation are divided into separate small rooms by steel plates. The small rooms can be arranged in various forms such as the Chinese characters "eye" and "level".

4. In order to facilitate monitoring and maintenance, the transformer room, high voltage room and low voltage room are all equipped with lighting devices.

5. The substation cover is designed with two layers to prevent heat radiation and increase the indoor temperature.

6. The transformer mainly uses natural ventilation. When the temperature exceeds the set value, the axial fan on the top will automatically start to control the room temperature of the transformer.

7. All rotating connecting parts are equipped with sealing devices, which have good moisture resistance.

Configuration of high-voltage side of box transformer

(1) The box transformer is divided into terminal type and ring network type based on the primary wiring method on the high-voltage side. The terminal type box transformer does not need to consider additional wiring: if the high-voltage side is one in multiple out or multiple in one out (mostly one in two out or three out, or two in one out or two out), it can be considered as a ring network type box transformer.

(2) European style box transformers have circuit breaker configurations on the high-voltage side, as well as load switch fuse combination protection. Considering the cost of box transformers, for box transformers with a capacity not exceeding 800 kV · A and low requirements for high-voltage side protection configuration, the latter is often used.

(3) The high-voltage load switches configured in European style box transformers are mostly FLN-12 sulfur hexafluoride load switches.

(4) The rated current of the high-voltage fuse melt for protection is selected according to the following formula:

Irr=KIgmax

In the formula, Irr - rated current of the melt, A; K - coefficient, generally taken as 1.3:

Igmax - Rated current on the high-voltage side of the transformer.

(5) Considering the safety of operation and maintenance, the high-voltage side configuration of European style box transformers should meet the following requirements.

① When the load switch is disconnected, there is a grounding device to ensure maintenance safety.

② The load switch and isolation switch ensure mutual locking to ensure safe operation.

(6) Due to the combination of high-voltage load switch and fuse, the American style box transformer is assembled in the same oil immersed box, including position load switch, backup fuse, plug-in fuse, and transformer. The ring network type is achieved by converting the internal connection terminals of the position load switch.
