The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be transmitted to a distance (the distance can reach m， the electronic computer can be equipped with an electronic computer socket， an intelligent transmitter and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor， so as to further improve the stability of the temperature maintenance system software.
1Transformer is a kind of power engineering equipment that converts working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering， it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss in the whole process of electromagnetic energy transmission. Therefore， the power consumption of the processing plant is all connected with kV switching power supply，power transformer price 1000kva which is converted into bottom voltage electromagnetic energy through transformer.
pWilwardThe clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand，RocklenOil immersed transformer gearProblems and solutions the fixed finger is at oclock， and the phasor of the phase voltage of the secondary side is used as the second hand.

NHow to select dry-type transformer
BTrustworthyThe proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text， we have already mastered the structure and characteristics of dry-type transformer. In this part， the cost of energy-saving transformers is significantly higher than that of traditional transformers， and the price factor is also a key factor endangering the popularization and marketing promotion of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers， the sales market has not been fully operated.
Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.
The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text， we have already mastered the structure and characteristics of dry-type transformer. In this part， we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.
Product linezPrinciple of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage， 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)，power transformer price 1000kva causing the magnetic induction voltage in the primary coil (or current).
QWhen checking the hook core， the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken，RocklenOil immersed transformer gearProblems and solutions turn on the photo flash when its light， and its short when its heavy. Therefore please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance， experts can inspect special tools， parts， insulation， etc. and deliver them after they are determined to be complete and reliable.
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

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，Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory 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
