NavadariDry type transformer MarketWhat is the defect processing method

Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation,NavadariTransformer capacity of distribution room, 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.

For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, power failure, etc.

Navadari.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

Dry type transformer manufacturer

Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.

Causes of fire in power transformer

In order to promote the use of energy-saving transformers, the Ministry of finance the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as 2012, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.

Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.

recommend.The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.

The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition,Navadari1600KVA price of power transformer, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

Due to poor sealing,NavadariOverload capacity standard of dry type transformer, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.

Oil leakage of cast iron parts

Safety production.35kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.

After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:

What is the important role of power transformer

Navadari.Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

Oil immersed transformer company

The key reason for oil leakage is that there are defects in cast iron parts
