Tanovsky kegurWhat qualifications are required to install power transformersWhat are the commonly used materials for construction

Equipped with a temperature controller, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm,Tanovsky kegurTransformer power transmission and ignition, overtemperature alarm and overtemperature tripping effect and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.Plug in the power with full load first,Tanovsky kegurDistribution 400 KVA transformer, 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.Tanovsky kegur,How to make up oil for oil immersed transformer?For the installation of lightning rod,Tanovsky kegurOil immersed self cooling transformer, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, power failure, damage to machinery and equipment, etc.Dong Ha,Power transformer manufacturerUnder normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.The noise of dry-type transformer comes from

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.The noise of dry-type transformer comes fromCustomer first,After the test, connect the data signal contact of the automobile relay with the alarm circuit, and adjust the overcurrent protection value.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.According to the condition of cracks, resulting in four wiring groups: & ldquo; y, Y & rdquo;, & ldquo; D, Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group, when UAB and UAB overlap, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.Discount,Dry type transformer manufacturerProtection mode for type selection of dry-type test transformerOperation and maintenance management of oil immersed transformerTanovsky kegur,Operation of oil immersed transformerWiring mode of dry-type transformer:Dry type transformer factory
