Oil immersed transformer operationThe appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only %Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.Total quality assuranceIf the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.Careless maintenance and insulation damageSound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window,PeterboroughSingle phase oil immersed transformer,PeterboroughOil immersed transformer, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well it will lead to common faults of oil leakage.Total quality management,The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm, rats, snakes, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, IP protective casing can be adopted which can avoid being equally divided with the above IP protective effects However, IP casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.Oil leakage of cast iron partsPeterborough,Wiring mode of dry-type transformer:Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.Power transformer manufacturer
