Which machines in industry use transformers

Writer: Hengfeng you electric Time:2023-03-31 views:times

Transformers are required in most areas where electricity is consumed. No protection, no working voltage, etc.
What are the differences between industrial transformer and civil transformer?
If it were all general, there would be no difference.
If it is a special rectifier, protection and starting transformer, it is different from the transformer of general distribution equipment.
This is no different from the industrial or civil type. Transformer model and specification.
 
Industrial transformer
Which machines in industry use transformers
 
This is not practical. If the output detection is 380V, the high voltage is generally 10kV, and some auxiliary high voltages are 6kV, the transformer is selected according to the working voltage. Price of large and medium-sized industrial transformers.
 
Should the design scheme of factory transformer be divided into industrial transformer and general transformer?
 
The transformer used in the processing plant can be selected differently according to the working environment and the power supply system of the processing plant. If the characteristic impedance of the switching power supply is small and the capacity is large, it is required to increase the characteristic impedance of the transformer and manipulate the short-circuit capacity pulse signal at the bottom voltage side of the transformer. Like some large capacity transformers, non-standard capacity transformers are applied according to load regulations to reduce investment projects and operation damage. There are also some transformers to be arranged in fire safety and explosion-proof areas, and explosion-proof transformers must be used; There are also provisions on transformer maintenance from the aspects of unique steam body. However, transformers are not divided into general transformers and industrial transformers, but into general transformers and transformers with special requirements. In fact, most transformers used in industry can be produced with general transformers
 
What is the specific method for industrial companies to calculate electricity charges based on transformer capacity?
 
Deduct the large industrial electricity price from customers, also known as the two-part electricity price, that is, the capacity electricity fee. The capacity electricity fee is calculated according to the capacity of distribution equipment transformer. For example, in Anhui Province, it is 38 yuan per kVA. If the distribution equipment transformer is 1000 KVA, the capacity electricity fee is 38000 yuan per month, and the other electricity consumption is multiplied by the electricity price to obtain the electricity fee. Excessive reactive power of industrial transformer.
 
The calculation of electricity charge shall be based on the sum of electricity consumption multiplied by the basic electricity price and electricity charge multiplied by electricity charge. Namely:
Base tariff = capacity × Basic electricity price
Electricity = electricity × electric
Power engineering = working capacity × Basic power engineering, power engineering × power engineering
Output power capacity: according to the capacity of the transformer (i.e. Transformer capacity); According to the company's large power consumption requirements. Choose one from two. How many kV is it? It is a large industrial transformer.
Electricity consumption: the watt hour meter shall be measured and verified every month. Marble industrial transformer.
Therefore, the key difference in electricity tariff calculation is the calculation of monthly basic electricity tariff.
According to the transformer capacity, the basic electricity price is 28 yuan / kVA. The basic electricity price is 38 yuan / kVA. If the specific power consumption capacity is less than 40% of the requirements for reporting large power consumption, if it exceeds the requirements for large power consumption, the basic electricity fee (76 yuan / kVA) shall be doubled.
Part of the power project is calculated according to the specific power consumption. Electricity consumption cost is used to compensate part of the variable cost expenditure of the power industry with the change of power supply. For small customers such as households, electricity charge is all the electricity charge they should pay;
For customers who implement two-part electricity tariff, the electricity tariff is only part of the electricity tariff, and the basic electricity tariff is the total amount of electricity tariff. The electricity charge is calculated according to the reading of the power factor meter in the battery charging electromagnetic energy measurement and verification equipment installed by the power industry at the customer.
Since the watt hour meter is a total value, the difference between the final reading value and the initial reading value shall be used to estimate the power consumption in the required time period. When installing voltage transformer and transformer in electromagnetic energy measurement and verification equipment, they shall be multiplied by the ratio of voltage transformer and transformer respectively.
The transformation ratio of voltage transformer (or transformer) is the ratio of rated voltage (or working voltage) of primary winding resistance of voltage transformer (or transformer) to secondary winding resistance
