Product category: product center box type substation Series Product Description: modular design, flexible installation, convenient traction, modular design, green environmental protection; High reliability and simple installation. Product details product introduction: modular design, flexible installation, convenient traction, ky-yb-35 (10) / 6 (0.4) mine mobile substation is divided into two basic types: mine vehicle type and mine sled type. Mine vehicle mounted substation is a combination of high voltage switch room, transformer room, medium and low voltage switch room and special transport flatbed truck. It can be towed by ordinary trucks for transportation and movement, providing power for various mining equipment, and has strong mobility. The mine sled type substation is a complete set of box type substation devices assembled on the sled shaped and specially strengthened steel chassis, placed on the flat ground of the mine power supply site, without foundation, for power supply, and towed by tractor when necessary, which is suitable for open-pit mining and mobile power supply in remote areas. Application conditions: A. ambient temperature + 40 ℃ ~ - 25 ℃; b. The altitude shall not exceed 1000 meters; c. When the relative humidity does not exceed 950A (+ 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:     This series of mine mobile substation is generally composed of high voltage switch room (including electric energy metering), transformer room, medium and low voltage switch room, etc. it can be equipped with DC power supply panel and relay protection room as required. These parts can be made into integral form or component form.     The box body is welded into a frame by section steel (channel steel and angle steel), and covered with aluminum alloy plate (composite sandwich plate, galvanized steel plate and stainless steel plate). The top cover of the box body is double hollow structure, and the top surface is made into slope shape to prevent water accumulation. All boxes are coated. The box transformer adopts the combination of natural ventilation and forced ventilation, and uses air conditioning and anti condensation device to control temperature and humidity. All functional units and channels are equipped with lighting devices to facilitate operation and maintenance. High pressure chamber     The high-voltage switch of this series of mine mobile substation mainly includes: high-voltage load switch, fuse combination, vacuum circuit breaker, vacuum load switch and SF6 circuit breaker, etc., which are equipped into fixed switch cabinet or movable switch cabinet. Transformer room     The transformer can be oil immersed power transformer, fully sealed oil immersed power transformer, on load voltage regulating power transformer and various types of dry power transformer. When equipped with 35kV oil immersed power transformer, the capacity generally does not exceed 2000kVA. When equipped with 35kV dry-type power transformer, the capacity generally does not exceed 1600KVA( 10kV disconnector, load fuse combination apparatus, vacuum circuit breaker and SF6 load switch can be used in medium voltage switch room of 6kV) and 10kV box type substation to assemble into fixed cabinet or jyn and KYN handcart cabinet, and 10kV capacitor compensation device can be configured. Low voltage room configuration     In the 0.4kV low voltage room of 35 / 0.4kV direct transformer box type substation, all kinds of knife fuse switch, universal circuit breaker, moulded case circuit breaker, intelligent circuit breaker, AC contactor, vacuum contactor and fuse are often used to form fixed switch cabinet or draw out switch cabinet. Of course, the complete set of switches are widely used. The basic series are: GGD type low voltage cabinet, GCK type, GCS type, MNS type draw out switch cabinet and capacitor compensation cabinet.     The relay protection room of 35kV box transformer substation can be equipped with DC panel, converter panel, traditional relay panel, microcomputer protection panel, simulation panel, communication panel and substation microcomputer integrated automation system, which are mainly configured according to the requirements of users. In a word, all electrical components, accessories, equipment and materials of mobile outdoor box type substation for mining use are domestic and international famous brand products, which are of high quality and durable. After long-term operation in harsh environment, it is proved that the design is reasonable, the quality is reliable, the operation is safe, and the economy is practical. Installation, use and maintenance: after installation or maintenance of mine mobile transformer, the following items shall be inspected and tested before putting into operation. 1) Check whether the box is in good condition and clean; 2) Whether the operating mechanism is flexible, whether it is stuck, and whether the operating force is too large; 3) Whether the main electrical appliances are reliable, accurate, flexible and normal; 4) Whether the transformation ratio and wiring polarity of instrument transformer are correct, whether the auxiliary contact of electrical appliance is accurate and reliable, whether the setting value meets the requirements, and whether the fuse core specification is correct. Whether the wiring of main circuit and auxiliary circuit meets the requirements of electrical schematic diagram; 5) Whether all electrical installation bolts and nuts are tightened, whether electrical installation is firm and reliable, and whether there is damage. Whether the bus connection, supporting porcelain, clamping parts and accessories are intact, firm and reliable; 6) The resistance of the guaranteed grounding system (between the main grounding point of each room and the guaranteed grounding conductor) shall be less than 0.1 Ω; 7) All relevant departments shall carry out voltage withstand test according to corresponding voltage level; 8) The insulation resistance of low voltage circuit and secondary circuit measured by 500V megger should be greater than 2m Ω; 9) Transformer oil in operation is sampled and analyzed once a year. The lightning arrester shall be tested every year before the thunderstorm season. The contact condition of the load switch shall be checked once a year and repaired in time. After each trip of the low-voltage switch, the reason should be found out first, and the switch can be closed only after the fault is eliminated.   Mining mobile substation can only be operated and maintained by qualified professionals or personnel approved according to the specified procedures.    Ordering instructions: 1. Primary scheme drawing, and indicate the color of substation; 2. Outdoor environment conditions of substation; 3. Name and power of load equipment in substation; 4. Selection requirements of components in substation.
