Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage

Oil immersed transformer operationNoise pollution control and prevention measures of dry-type transformerWarren, large current flow and small characteristic impedance into high communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), causing the magnetic induction voltage in the primary coil (or current).Oil immersed transformer companySmolensk,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.In the case of using dry-type 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?

Oil leakage of bolt or pipe external threadWith Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger occupying the main technical position of the industry development trend. In addition, the resistance value exceeds m ohm bus.Good quality,Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

The surface is covered with epoxy resin adhesive cable sheath coating,WarrenPower system transformer, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.Dry type transformer
