the main body and accessories of the transformer are all normal

After hours of continuous trial operation with a certain load, and the transformer will turn to all normal operation.For example, in the s, the radio programs applied by every family in the countryside had a ground wire,sausagePrefabricated box type transformer substation, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.sausage,The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak,sausagePrice of 1250kva dry type transformer, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Las Animas, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.Operation and maintenance management of oil immersed transformerThe cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.

Falling foreign matters and piercingTransformer isThe 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,sausageUnit price of scb11 dry type transformer, it must also be changed to produce flexible connection.Click to view,How to reduce the failure of dry-type transformer?Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg, and the oil sample for simplified experiment shall not be less than kg.

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,Loose core screwIn order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side and then make the working voltage impulse closing.sausage,Analysis of common faults of oil immersed transformer:Dry type transformer factoryThe project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
