() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side， it shall be installed between the disconnector and low-voltage composite insulator，SeneckDry type transformer 10 / 0.4kV， or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side， it shall be installed on both sides of the low-voltage composite insulator， and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.
When the full load test is carried out and everything is normal， the load can be connected.
SeneckPower transformer is indispensable for power stations and substations， but we must pay attention to many problems in the whole process of applying power transformer.
When using the oil sample of the power transformer in operation， it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet， and then take the oil sample.
ElmosaWiring mode of dry-type transformer:
What is the wiring mode of dry-type transformer?
Dry type transformer manufacturer
When the manufacturer of the power transformer samples from the automobile oil tank， after opening the sealing cover， use the cleaned and dried rubber stopper to the oil. At the same time，SeneckAC step-up transformer， clamp the branch pipe with your thumb， and loosen your thumb to make the oil enter the pipe
The insulation between silicon steel sheets is damaged， resulting in overheating and melting of the iron core;
Power transformers are used in all walks of life
equipment maintenance When the power transformer operates at full load， it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large， but also make the transformer operate at full load or load for a long time， expand the proportion of full load loss， reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Dry type transformer
In fact， ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them， safety factor grounding device can be divided into grounding protection， anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
Oil leakage of heat pipe radiator
DiscountIf 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.
The top and middle of the transformer oil tank， the flange plate， barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage， which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment， the output capacity can be increased by %.
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts，SeneckDry type transformer equipment， with good strength and stiffness which is conducive to adjusting the data and has a unique and neat style.
When the screw of the through core extruder holding the iron core of the transformer is loose， there are screw cap parts left on the iron core， or small metal materials fall into the transformer， the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak， squeak & rdquo; It"s like a magnet sucking a small washer， while the working voltage， current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer， and can be solved until power failure.
