AnshanPower supply transformer manufacturerMain parameters of working principle

Before no-load impulse closing, the transformer shall be placed for h,The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %, which shall not exceed % compared with the last accurate measurement result.Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, production and manufacturing process and quality standards of automobile oil tank,AnshanPower transformer specification, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.Abay,Operation of oil immersed transformerIn 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.Connection group structure of dry-type transformer

Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.Transformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered coupled with the constraints of factors such as low threshold in the field,AnshanMining dry-type power transformer, lack of evaluation and specifications uneven companies, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.Noise dispersion of dry-type transformerQuality management,Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Oil immersed transformerAnalysis of common faults of oil immersed transformer:

The switching power supply lacks one phase of power;Design brand, the safety and fire safety technical specifications on the spot shall be strictly implemented.Several detection methods for installing transformerHigh voltage fuse of transformer breaks one phase;Anshan,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.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.Power transformer
