The manufacturing process of dry-type transformer is very process， and must be technically as a certain pillar. Only in that way， the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
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， ignition， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
ZedingAt that time， only a few companies in China could produce kV high-voltage transformers，ZedingOil immersed transformer components， and the market share of high-voltage transformers was basically monopolized by overseas leaders.
Before no-load impact closing， and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
Cha RongWhen 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， current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer，ZedingPower tube， and can be solved until power failure.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials， porcelain laminated glass and other materials very well， so as to achieve the pressure management of oil leakage.

What is the wavelength of oil immersed transformer?
The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer， kW. Active power loss of small capacity transformer: when a pump room is in normal operation， two pumps are started separately and each pump is driven by kW motor， so the usual load is KW， CST = . One kva transformer was originally configured， and the capacity utilization rate introduced by the transformer manufacturer is only %
Then clamp the branch pipe with your thumb， clearly put forward the glass test tube， rotate and release the oil in the tube to clean the sampling tube， carry out it twice， and then draw the oil sample.
Professional is kingThe 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 electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

A 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.
In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer， prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.
Marketing DepartmentThere are many connection groups of dry-type transformers， and the selected structures and connections are also different. Then， what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
The efficiency of transformer is closely related to the output power level of transformer. Generally， the greater the output power， the smaller the output power， the lower the efficiency.
When oil samples are used， the safety and fire safety technical specifications on the spot shall be strictly implemented.
ZedingHow to reduce the failure of dry-type transformer?
In the case of using dry-type transformer，ZedingOverload of distribution transformer， customers must master the method of wiring. If there are problems in wiring， it is easy to cause common faults in application. So， what is the wiring mode of dry-type transformer?
Then clamp the branch pipe with your thumb， clearly put forward the glass test tube， rotate and release the oil in the tube to clean the sampling tube， carry out it twice， and then draw the oil sample.
