Product category: product center box type substation Series Product Description: low loss, high output, obvious advantages of energy saving, strong integrity, compact structure, safe and reliable operation; Beautiful appearance, quick installation and convenient construction; Easy to operate, high reliability. Product introduction: ybh series amorphous alloy prefabricated substation is mainly composed of high voltage switchgear, amorphous alloy transformer and low voltage switchgear, which is a complete set of indoor and outdoor power transformation and distribution equipment. The difference between ybh series amorphous alloy prefabricated substation and ordinary substation is that the core of power transformer is used with smaller no-load loss, higher power consumption and lower power consumption It is made of non gold alloy strip with better strength, which ensures the superior performance of low loss and low heating in the use of substation.   Application conditions: A. ambient temperature + 40 ℃ ～ - 25 ℃; b. The altitude shall not exceed 1000 meters; c. When the relative humidity does not exceed 95% (+ 25 ℃), it is allowed to reach 100% in a short time; d. It should be installed in a place without fire, explosion, chemical corrosion and severe vibration; e. Special use conditions can be determined through negotiation with our company.   Product structure:     The box is a frame structure, which is welded by section steel or assembled by steel plate. The frame is coated with special paint, which has strong mechanical properties, weather resistance and corrosion resistance. When the prefabricated (box type) substation is an integral structure, the box is divided into three relatively independent chambers, namely high voltage chamber, transformer chamber and low temperature chamber. The lighting of each room is opened and closed automatically with the opening and closing of the door.      There is a heat insulation layer on the top of the prefabricated (box type) substation to prevent condensation due to the rapid change of temperature in the box in high temperature and cold areas. An additional heat insulation layer can be installed around the box. In order to stabilize the temperature in the box, the transformer room and low voltage room are equipped with automatic temperature control devices.   Box structure: high pressure chamber     The high-voltage room is equipped with high-voltage ring main unit or kyn28 cabinet type, with perfect "five prevention" function. The high-voltage switch can be of compressed air type, gas producing type, SF6 load switch and vacuum circuit breaker. High voltage cabinet has a variety of protection functions such as short circuit to transformer and overload. Transformer room     The transformer with core made of new type amorphous alloy strip has smaller magnetic retention, higher resistance coefficient and thinner thickness. In the actual use process, the main advantages of this transformer are as follows: 1. The no-load loss is 70% - 80% lower than that of ordinary dry transformer, and the energy saving effect is remarkable; 2. Nomex Paper insulation system is adopted, with high flame-retardant, explosion-proof, fire-proof grade, high heat resistance grade (H grade) and stronger overload capacity; 3. It has the advantages of small partial discharge, high insulation level, long service life and better environmental protection. Low pressure chamber     Low pressure chamber is divided into internal operation and external operation. Indoor metering cabinet, main incoming cabinet, outgoing cabinet, capacitor cabinet and contact cabinet (when there are two transformers) can be installed, with the overall function of low-voltage switchgear. The general 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 controlled manually or automatically for automatic compensation. The capacitance reactive power compensation capacity is generally 15-30% of the transformer capacity.
