NakskovTransformer electrical testIndustry production efficiency improvement

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, and overload is not allowed in the whole process of operation.When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.Nakskov,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, 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,NakskovOil immersed transformer, and the transformer shall be tripped quickly.When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.Rousselale,Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.Fault judgment of power transformerDue to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).

Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.Dry type transformer manufacturerHow much is it,Power transformers are used in all walks of lifeWhen leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.Oil leakage of heat pipe radiator

The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Quality Assurance,The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, the good model is the solid model of infinite transformer core column, but there are many calculation methods.Dry type transformer, a static electrical equipment,NakskovSC series dry type transformer, 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, with a compliance rate of %& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.Nakskov,(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise,NakskovIs the dry-type transformer a box transformer, 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.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.
