SnorePower traOutdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling,Rempat River4000kva dry type transformer,Rempat River3150 power transformer,Rempat RiverPrice of 1000kW dry type transformer, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.
If the power transformer stops running for more than 72h (if the allowable time should be reduced when the ambient humidity is & amp; gt; 95%), it should be insulated before putting into use, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh, and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).
Rempat River.How to maintain dry-type transformer?
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, if the tap changer is not in time, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
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.
During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Noise pollution control and prevention measures of dry-type transformer
Energy costs.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.
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.
Operation and maintenance management of oil immersed transformer
When the full load test is carried out and everything is normal, the load can be connected.
Safety production.Dry type transformer
At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
What is the reason for the shutdown of power transformer?
Rempat River.Wiring mode of dry-type transformer:
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
