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 smaller the loss to output power ratio and the higher the efficiency. On the contrary the greater the output power, the smaller the output power, the lower the efficiency.
What is the wavelength of oil immersed transformer?
.Operation of oil immersed transformer
Dry type transformer factory
If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
How is the quality level of dry-type transformer compared with foreign countries?
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.
Total quality management.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, which is not suitable for too large or too small.
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
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.
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,Qinglai25kV power transformer, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Lets see.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.
It can be seen from the above that from the perspective of power saving, in some cases, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo; Even less than & ldquo; Great Lars, little dragons & rdquo;, Therefore, the loss of transformer full load and load must be considered in the calculation, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: 3. The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, the operating load and rated capacity of the transformer 1. Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, and the rate is large when the specific copper loss is equivalent to iron loss.
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, which is not suitable for too large or too small.
Qinglai.The flange surface is uneven,QinglaiMain transformer and distribution transformer, the tightening bolts are loose, so that the bolts are not tightened well, resulting in oil leakage.
Analysis of common faults of oil immersed transformer:
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
