ODM Discount Substations Near Me Suppliers – 10kV 20kV ZGS combined transformer – JSM TRANSFORMER Detail:

Combined transformer (also known as American box change), as an important power supply unit in the cable distribution network, the product puts the high-voltage load switch and high-voltage fuse in the cabinet of the transformer. The fuel tank adopts a fully sealed structure, and the transformer oil in the box has good insulation performance and heat dissipation performance. It has the advantages of small size, light weight, convenient installation and maintenance, safety and reliability, and beautiful appearance. Widely used in urban, residential quarters, hotels, hospitals, factories, mines, oil stations, airports, railways, terminals and other outdoor power supply sites.Small Size And Compact Structure
The floor space is only 1/3-1/5 of the domestically produced box with the same capacity. Fully sealed, fully insulated structure, no insulation distance. Excellent performance, safe and reliable, low loss, low noise.Good Compatibility
The high-voltage incoming line adopts cable plug, which can be equipped with zinc oxide arrester to meet various low-voltage feeding requirements. According to user requirements, low-voltage metering and shunting can be added.
Strong Overload Capacity
S11 type transformer, it is divided into three parts: main high pressure chamber, low pressure chamber and transformer. It is conventionally arranged in “good” type, and the high pressure side adopts V type or T type load switch plus two-stage fuse. The protection can be used for the ring network and for the terminal, and the power supply mode is flexible and reliable.

Features:

1. Safe & Reliable
Shell generally adopts aluminium zinc steel plate, frame with a standard container material and production process which has good anti-corrosion performance for 20 years guaranteed. The inner sealing plate is made of aluminum alloy buckle plate, and the sandwich is made of fireproof and thermal insulation material. The air conditioning and dehumidification device are installed in the box. The operation of the equipment is not affected by the natural climate environment and external pollution, and the normal operation can be guaranteed under the harsh environment of -40℃ ~ +40℃. The primary equipment in the box is fully enclosed, the product has no exposed live part, which can completely achieve zero electric shock accident, the whole station can realize oil-free operation, high security, the secondary use of microcomputer integrated automation system, which can realize unattended.

2. High degree of automation
Total station intelligent design, protection system adopts microcomputer integrated substation automation equipment, installation, which can realize telemetry, remote communication, remote control, remote regulating. Each unit has independent operation function. The relay protection function is complete, which can set the operating parameters in the distance, control the humidity and temperature in the box body and alarm the smoke in the distance, so as to meet the requirements of no one on duty.It can also realize remote image monitoring according to the need.

3. Factory prefabrication
When designing, as long as the designer according to the actual requirements of the substation, provide a main wiring diagram and the design of equipment outside the box, manufacturers can carry out a installation and debugging of all equipment, truly realize the substation construction factory, shorten the design and manufacturing cycle. On-site installation only needs box positioning, cable connection between boxes, outgoing cable connection, protection calibration, transmission test and other commissioning work. The entire substation from installation to commissioning only needs about 5 ~ 8 days, greatly shortening the construction period.

4. Flexible combination mode
Box type substation structure is compact, each box constitutes an independent system, which makes the combination of flexible, on the one hand, we can all use the box, so that 35kV and 10kV equipment all installed in the box, the composition of the whole box type substation; 35kV equipment can also be installed outdoors, and 10kV equipment and control and protection system can be installed inside the box. This combination mode is especially suitable for the transformation of old rural power grid stations. In short, there is no fixed combination mode of compact substation, and the user can combine some modes freely according to the actual situation to meet the needs of safe operation.

5. Cost savings
The box-type substation reduces the investment by 40% ~ 50% compared with the conventional substation of the same scale. The civil engineering (including land acquisition costs) of the box-type substation is more than 1 million yuan less than that of the conventional substation based on the calculation of the 4000kVA scale of the 35kV single main substation.From the perspective of operation, box-type substation can carry out in-condition maintenance, reduce the maintenance workload, and save about 100,000 yuan of operation and maintenance cost every year, and the overall economic benefit is very considerable.

6. Small occupied area
Taking the 4000kVA single main substation as an example, the construction of a conventional 35kV substation will occupy an area of about 3000㎡ and require large-scale civil engineering.The selection of box-type substation, the total area of the maximum 300㎡, only for the same scale of the substation covers an area of 1/10, can be installed in the center of the street, square and factory corner, in line with the national land saving policy.

7. Beautiful shape
Box shape design is beautiful, on the premise of ensuring the reliability of power supply, through the selection of box substation shell color, so easy to coordinate with the surrounding environment, especially suitable for urban construction, it can be used as a fixed substation, can also be used as a mobile substation, with the role of ornament and beautification of the environment.
