details of Tianjin high and low voltage integrated distribution cabinet

box type substation. The products have the characteristics of strong integrity, small floor area, small investment, convenient installation and maintenance, beautiful appearance, strong weather resistance, etc. It is a complete set of outdoor and oil transformation and distribution equipment composed of high-voltage switchgear, power transformer and low-voltage switchgear

oil transformer has low cost and convenient maintenance, but it is flammable and explosive. Due to its good fire resistance, the dry transformer can be installed in the load center area to reduce voltage loss and power loss

since box type transformers play such an important role, what serious consequences will occur if voltage instability occurs? The engineer of the transformer manufacturer explained the main influencing factors as follows: 1 When the voltage of the box type transformer is unstable, it will produce an unbalanced current several times higher than the normal current, and the temperature of some metal parts of the equipment will rise sharply, resulting in a short circuit of the dry-type transformer, which may be burned directly. It increases the maintenance cost of electrical equipment and shortens the service life. 2. In production and life, the unstable voltage of the dry-type transformer makes the three single regulators work without automatically reducing the acceleration scale of the experimental machine, resulting in an increase in the loss of the dry-type transformer (no-load loss and load loss)

box type substation can effectively prevent the invasion of small animals. The maintenance of the transformer is easily pushed and pulled out by a detachable trolley. Four corresponding lifting bolts that can be pulled out and pushed are set on both sides of the box base, and four supports with the same function are set on both sides of the roof eaves, which can be lifted and transported as a whole. This series of combined (box type) substation is a complete set of outdoor and oil transformation and distribution equipment composed of high-voltage switchgear, power transformer and low-voltage switchgear. This product has the characteristics of complete set, small floor area, small investment, convenient installation and maintenance, beautiful appearance, strong weather resistance and so on

dry type transformers are generally suitable for power distribution. Most of them have a capacity of less than 1600KVA and a voltage of less than 10kV. Some of them do it and put them into the piston with a voltage of 35kV

functional characteristics of box type transformer: This product is a frame structure, welded with section steel, covered with aluminum alloy plate outside the frame, and coated with special paint, so that it has strong mechanical properties, weather resistance and corrosion resistance. When the combined (box type) substation is an integral structure, the box is divided into three relatively independent chambers with steel plates, namely, high-voltage chamber, transformer chamber and low-voltage chamber. The lighting of each room is automatically shut down with the opening of the door.? The "top" part of the box type substation has a thermal insulation layer. In high temperature and cold areas, the temperature in the box is easy to accumulate and change and condense, so the thermal insulation layer around the box can be added. In order to stabilize the temperature in the box, automatic temperature control devices are set in the pressure chamber and low-pressure chamber of the variable order experimental machine

service conditions of box type substation: the low voltage room is divided into two assembly forms: corridor type and non corridor type. Indoor metering cabinet, main switch cabinet, outgoing cabinet, capacitor cabinet and contact cabinet (when there are two transformers) can be installed, which has the overall function of low-voltage switchgear. Generally, the metering cabinet and the main switch cabinet are integrated, that is, the upper part of the cabinet is the instrument, the metering box, and the middle and lower part is the automatic air switch, lightning arrester, and transformer. The capacitor cabinet can be manually and automatically controlled for automatic compensation. The capacitance reactive power compensation capacity is generally% of the transformer capacity, and the compensation capacity can also be increased or reduced according to the needs of customers
