Before application， the sampling container shall be cleaned with vehicle gasoline， soapy water or other organic solvents (such as trisodium phosphate) except oil stains， and the water can be evenly distributed from the bottle， and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration， the bottle cap shall be tightly closed and cannot be opened before application.
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.

For the leakage that has already occurred， find the leakage point first， which can not be ignored. For the position with serious leakage， shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage， the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation， the goal of long-term treatment of leakage can be achieved.
SaranskIt is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials， porcelain， laminated glass and other materials very well， so as to achieve the pressure management of oil leakage.
After the oil is drained， all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack， and the lifting point shall be on the common earrings or bolts. If necessary the human resources traction belt shall be used as a guide.
Manufacturing process and steps of dry-type transformer
When we apply oil immersed transformer， we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
Precautions for trial operation of power transformer manufacturers
The hanging core of dry-type transformer is a vital part
Affordable priceIn fact， ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them safety factor grounding device can be divided into grounding protection， anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.

Manufacturing process and steps of dry-type transformer
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil， resulting in short circuit between coils， two-color short circuit or short circuit on the ground， resulting in the ignition of power transformer. Therefore， the insulation compressive strength of power transformer shall be tested before installation and operation，Meherpur DistrictWhat is the price of 1600KVA transformer， and overload is not allowed in the whole process of operation.

The secondary inductive equipment of the distribution station (such as transformer， voltage transformer， automobile relay， AC， etc.) operates normally. According to the AC current， buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults， there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method， the winding of oil immersed transformer is generally divided into multiple modules and each module is replaced by an equivalent circuit， and its power circuit includes an inductance and vertical capacitance，Meherpur DistrictTechnical parameters of scb12 dry type transformer， a capacitance to ground or capacitance between windings， They also have mutual inductors between the inductors of each module， and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
Meherpur DistrictThe insulating layer in the middle of the silicon steel plate is aging， the anchor bolt cover with the iron core is damaged， resulting in heat，Meherpur DistrictDistribution transformer maintenance， temperature rise， and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value， please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.
If 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.
