Projector-specific isolation transformer
A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are a primary coil, a secondary coil, and an iron core. Shanghai Lingyue Transformer Factory produces three-phase transformers, control transformers, isolation transformers, single-phase transformers, rectifier transformers, UPS transformers, combined transformers, dry-type transformers, oil-immersed transformers, mining transformers and other related transformer products.
Classification of transformer series
The DG series single-phase dry-type transformer produced by our company has the advantages of small size, light weight, simple maintenance and reliable operation. The design and production are strictly in accordance with IEC international standards and relevant GB national standards. It is suitable for various industries such as communications, electric power, chemicals, light industry, etc., and can be used as lighting power and power sources. It is also widely used to import important equipment, precision machine tools, machinery and electronics. Equipment, such as power transformers.
Our company uses high-quality materials and advanced process technology to professionally produce SG, SBK series three-phase dry-type isolation transformers, which are professional transformers for imported equipment from Japan, the United States, France, Taiwan, and South Korea.
The running light transformer is also called a step-down transformer. Generally, 36V and below safety voltage is used as lighting power for factory driving. Generally there are three-phase running lamp transformers and single-phase running lamp transformers
According to customer requirements, we can produce various input and output voltage levels, connection groups, adjust the number of taps and position winding capacity allocation, the configuration of secondary single-phase windings, the use of rectifier circuits, whether it is required to have a casing, etc .; User requirements are carefully designed and manufactured:
This series of low-voltage and high-current transformers need to be stepped down from the power supply voltage to increase current regardless of testing and heating, so that the low-voltage current can reach thousands or 10,000 amps. The high voltage of this series of products is generally 220 volts, 380 volts and 650 volts. The low voltage of this series is different by the magnitude of the up current, and it is a series. This series of low-voltage output uses safe voltages of 3V, 6V, 9V, 12V, 15V, 24V, 36V, etc. (can be designed according to customer requirements)
This series of transformers are composed of silicon steel sheets and coils. The primary and secondary windings are separated. When the secondary has only one winding, it bears the full rated capacity of the transformer. For example, when the secondary pole has both control, lighting and indication windings, Then the sum of the capacities of the windings is equal to the rated capacity of the transformer; but in principle no more than three windings. The voltage and capacity can be arbitrarily selected according to customer requirements. The transformer has special ground wire screws and signs. The limit uses the tile-type washer combination screws. The limit terminals are protected.
Many international standards have special regulations on the power distribution system in the medical field, especially those where life is critical, such as operating rooms, intensive care units, and cardiac care units. Nowadays, for internationally important places such as operating rooms, ICUs, and CCUs in the medical field, local "neutral-point ungrounded power supply systems" (IEC standards call them "medical IT systems" or "isolated power systems") are often used for power supply. Necessity of choosing IT system (neutral point ungrounded power distribution system) in medical field
ZSG (ZB) series three-phase dry-type rectifier transformer is an important part of rectifier equipment. It forms a rectifier circuit system with various rectifier devices. In order to convert AC power to DC power, the rectifier transformer first converts the voltage of the AC power grid into a voltage of a certain size and number of phases, and then passes through a rectifier (rectifier) and outputs it to the DC drag device.
The establishment of a new neutral-ground in the isolation transformer can relieve the common-mode interference and other neutral problems in the power grid. The isolation transformer converts the three-wire △ wiring to a four-wire Yo system, and the shielding further eliminates the high-frequency pulse interference coupled by the transformer. And noise, although the shielded isolation transformer can effectively prevent various NG interference (pulse and high frequency noise), but the transformer must be properly and properly grounded, which is very strict.
This series of products is specially designed for voltage conversion needs. It is made of imported cold-rolled silicon steel sheet stacked, high temperature resistant and high insulation performance composite materials. The coil air groove can effectively reduce the coil temperature; the special resin impregnated paint has Magnetic permeability and low loss, low noise, low temperature, radiation resistance and non-toxicity, maintenance-free, high environmental protection and so on. Built-in high impedance, high space efficiency and power conversion efficiency. The leakage reactance value, wiring method and voltage level of the product can be ordered as required.
This autotransformer is installed in the main components of the autotransformer starter cabinet. The voltage is 220V, 380V, 660V, 1000V and below. The three-phase squirrel-cage induction motor with a frequency of 50Hz to 60Hz and a power of 800 kW and below is used as a step-down start use.
