The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Columba,According to statistics, to occupy the main global technical position, the transformer industry depends on two key data commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production manufacturing and application of dry-type transformers all over the world,ColumbaWhat is the price of 1000 KVA transformer, but it is not a big country.Oil immersed transformerStaffanstorp, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound,ColumbaThree winding power transformer, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, and can be solved until power failure.

Power transformers are used in all walks of lifeTransformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field,ColumbaTransformer device, uneven companies, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.Quality improvement,Noise solution of dry-type transformerPower transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.For kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.

Power transformer plantDiscount,What is the wiring mode of dry-type transformer?Relevant responsible persons of the transformer Federation of China Household Appliance Industry Association show that the development prospect of transformers in China in the future is still the development trend of environmental protection, low noise, fire safety and explosion-proof and high reliability. There are two key development prospects: one is the development trend of high voltage and high voltage, energy conservation and miniaturization. The former key is applied to the long-distance substation project route, and the latter key is applied to the substation project route in big cities.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, carry out it twice, and then draw the oil sample.Columba,According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.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, 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.
