Big haguiOld box transformerProduction and sales prices and situation

Power 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.kV 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.Big hagui,How to select dry-type transformerConnection group structure of dry-type transformerKasamwa,Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.The 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.

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment,Big haguiOil immersed dry type transformer, 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.If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption,The switching power supply lacks one phase of power;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,Big hagui2200 oil immersed transformer, it is very easy to cause fire accidents, power failure, damage to machinery and equipment,Big haguiDry type transformer temperature, etc.Wiring mode of dry-type transformer:

Dry type transformer manufacturerCustomer first,Oil immersed transformer operationOnce the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.Dry type transformer companyBig hagui,Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.Power transformer manufacturerThe raw materials of Fushi blue can be used for bonding, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
