(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.Ulsk heradiest,The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer,Ulsk heradiestManufacturer of 80 KVA dry type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.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,Ulsk heradiestVarious models of transformer, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.Canelones,Method and process of taking oil sample of power transformerFalling foreign matters and piercingThe method and whole process of taking oil sample of power transformer are as follows:

The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, 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.Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.The key reason for oil leakage is that there are defects in cast iron partsMeticulous workmanship,Oil leakage of bolt or pipe external threadAccording to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.Different diversion methods dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

For no-load impulse closing of transformer, pay attention to the following matters:Let's see,What is the reason for the shutdown of power transformer?During the operation of the transformer,The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized,Ulsk heradiestPower transformer technology series, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.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.Connection group structure of dry-type transformer
