Miniaturized European Box Type Substation

◆ Overall structure

1. YB□-12 Miniaturized European Box Type Substation are mainly divided into three parts: high-voltage switch room, transformer room and low-voltage switch room, which can be transported separately.

2. The product adopts a unique large-cycle heat dissipation design to ensure the temperature rise level of the product, and separate sealing between rooms will not form heat exchange between rooms.

3. The product shell is made of high quality stainless steel plate. All parts of the steel plate structure have undergone special anti-corrosion treatment, and the stainless steel plate structure has strong corrosion resistance and good mechanical strength.

4. The product can be directly installed indoors without additional building foundation, which saves cost and space and is convenient to install.

◆ High Voltage Chamber

SF6 gas-filled switchgear independently developed by our company is adopted for high voltage, and all switchgear and busbars are sealed in a closed stainless steel box with no exposed charged body outside. Safe operation and high reliability; Fully modular design, all modules can realize the connection mode of side outlet and top expansion according to the power consumption requirements, and meet the needs of power supply scheme to the maximum extent.

◆ Low Voltage Chamber

The low-voltage side inlet and outlet lines are all made of new molded case circuit breakers, which are small in size, free from arcing and easy to replace. Multifunctional intelligent comprehensive protection controller and new integrated reactive power compensation device.

◆ Transformer Chamber

The transformer is fully insulated with epoxy resin, and the insulation and heat resistance level is F, and the transformer does not have any combustion-supporting materials, and does not produce any gas or other intermediate products that are not conducive to the environment during operation, so it has the characteristics of good flame retardancy, environmental protection and energy saving.

◆ Internal Link

The voltage transformer and Chinese solid switch are connected by the company's solid insulated cable accessories, which are completely insulated and safe and reliable

● Function and Characteristics

The high voltage chamber of Miniaturized European Box Substation is composed of high voltage load switch, high voltage fuse and lightning arrester, which can stop power transmission and have overload and short circuit protection at the same time. The low-voltage chamber is composed of low-voltage air switch, current transformer, ammeter and voltmeter. Miniaturized European Box Substation adopts leading processing technology and has good corrosion resistance and wear resistance. Its advantages are flexible combination, convenient transportation, installation and construction, low cost, no pollution and safe and reliable operation. At the same time, the Miniaturized European Box Substation is a device with high degree of automation, and it is designed intelligently, which can fully protect all parts and meet the needs of unattended. Generally speaking, Miniaturized European Box Substation is the type of box transformer that saves investment and gets the fastest effect.

● The High Voltage Chamber

The high voltage chamber is generally protected by a combination of load switch and fuse. After one phase of the fuse is blown, the three-phase linkage trips. Load switches are available in compressed air type, vacuum type, sulfur hexafluoride type, etc., which can distribute operating mechanism and realize automatic upgrade; The fuse is a high-voltage current-limiting fuse with a striker, which has reliable action and large breaking capacity. See the table below for the main technical parameters. For transformers above 800kVA, vacuum circuit breakers such as ZN12, ZN28 and VS1 can be selected for protection.

● The Low Voltage Chamber

The main switch side of Low-voltage chamber adopts universal or intelligent circuit breaker, which can selectively protect the circuit; The outlet switch adopts a new type of plastic shell switch, which is small in size and short in arcing, up to 30 circuits; There are contactor and contactless switching modes for users to choose from.

● The Transformer

YB□-12 Miniaturized European Box Type Substation choose low-loss, oil-immersed, fully sealed S9, S10 and S11 series transformers, or choose resin-insulated or NOMEX paper-insulated environmental-friendly dry-type transformers, and the bottom is equipped with a trolley to facilitate the entry and exit of the transformer.
