Oil leakage of heat pipe radiatorBefore no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.Letunov ,Dry type transformer, a static electrical equipment is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the kinds of dry-type transformer commodities manufactured by manufacturers in provinces and municipal districts across the country, kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of %& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.Noise solution of dry-type transformerEmbu,Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.Power transformer factoryOn load commissioning:

Oil immersed transformer companyOvertemperature 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 ℃,Letunov Model of three-phase oil immersed transformer, 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,Letunov Model and specification of power transformer,Letunov Distribution transformer gear, and the transformer shall be tripped quickly.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.Latest consultation,Protective measures for damping of dry-type transformerIn specific daily life, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation etc. and deliver them after they are determined to be complete and reliable.

The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.project,It includes the performance and main uses of insulating layer materials, various insulating layer parts, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, and then draw the oil sample.Letunov ,Loose core screwFalling foreign matters and piercingHigh voltage fuse of transformer breaks one phase;
