NicaraguaTransA zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.
Causes of fire in power transformer
Iboho.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation,IbohoPower converter transformer, offset, cracking, loosening, ignition smoke oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, visual inspection is one of the common methods of equipment inspection.
Loose core screw
.Some are tied with plastic tape,IbohoTemperature standard for oil immersed transformers, and some immediately press the two edges together, because the socket can not be pressed firmly during installation,IbohoProspect of distribution transformer, and there is still oil leakage without sealing effect.
Wiring mode of dry-type transformer:
Connection group structure of dry-type transformer
When the transformer is put into operation, if the tap changer is not in time a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, 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.
Once 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.
Noise dispersion of dry-type transformer
Quality assurance.The method and whole process of taking oil sample of power transformer are as follows:
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.
What is the reason for the shutdown of power transformer?
Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.
Sampling inspection.Oil leakage of bolt or pipe external thread
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
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.
Iboho.In order to better carry out the experiment of power transformer oil, and the oil sample for simplified experiment shall not be less than 1kg.
What is the wavelength of oil immersed transformer?
In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
