StragaScb13-1250kva dry type transformerInvestment Analysis

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).The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.Straga,What is the cause of power transformer core failure?Analysis of common faults of oil immersed transformer:Pirkkala,There 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.How to reduce the failure of dry-type transformer?(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.

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.Maintenance contents of power transformerWhen the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Good reputation,The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor,StragaOil immersed transformer components, power transformer winding and power transformer tapping power switch are analyzed below:Manufacturing process and steps of dry-type transformerThere 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 zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line it will be grounded from the surrounding grounding body.Test method,Dry type transformer companyRelevant responsible persons of the transformer Federation of China Household Appliance Industry Association show that the development prospect of transformers in China in the future is still the development trend of environmental protection, low noise, fire safety and explosion-proof and high reliability. There are two key development prospects: one is the development trend of high voltage and high voltage, especially kV and kV. The second is the development trend towards environmental protection,StragaPower transformer parameters, energy conservation and miniaturization. The former key is applied to the long-distance substation project route, and the latter key is applied to the substation project route in big cities.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,When oil samples are used and can be solved until power failure.Straga, the safety and fire safety technical specifications on the spot shall be strictly implemented.In terms of the place of use, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;High voltage fuse of transformer breaks one phase;
