Keyword: PCB transformer terminal connector, PCB terminal connector, PCB terminal block
A new type of PCB transformer terminal connector, has been widely used in electrical and electronic engineering industry: large transformer, etc. Transformer PCB terminal connector, convenient connection, both the structure design screw connection strong characteristic, can quickly and easily installed on 2 x10mm guide rail. Product design IEC60947-7-1 and other international standards.
Shanghai lian jie electrical professional committed to the development and manufacture of terminals, the company has the advanced technical research and development, and research and development equipment, the production of PCB terminal blocks, the user's consistent high praise, Shanghai lian jie in "revitalization of the national brand" for the development of the power, in the current situation in connector industry short period.
The transformer is one kind of use of electromagnetic should be mutual inductance, transform voltage, current and impedance of the device. The function of the transformer are mainly: voltage transformation; Current transformation, impedance transformation; Isolation; Voltage (magnetic saturation transformer), etc.
General classification of common transformer can be summarized as follows:
(a) by cooling way points:
(1) the dry type transformer: rely on the natural air convection cooling or increase the cooling fan, used in high-rise buildings, more high speed charge site electricity and local lighting, electronic circuit and other small capacity transformer.
(2) the oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed natural cooling and oil-immersed forced-air cooling, oil immersion cooling, forced oil circulation, etc.
(b) according to the winding form points:
(1) double winding transformer: used to connect two voltage grade of power system.
(2) three winding transformer: generally used in the regional power system transformer substation, connecting the three voltage levels.
(3) the self coupling transformer: used to connect to different voltage of power system. Also can be used as ordinary booster or fall after the transformer.
(c) according to the form of core points:
(1) core transformer: used for high voltage power transformer.
(2) of amorphous alloy transformer, amorphous alloy iron core transformer is to use new magnetic materials, no-load current fell about 80%, energy saving effect is the ideal distribution transformer, especially suitable for rural power grids and developing regions such as load rate is low.
(3) shell type transformer: used for large current special transformer, such as the electric furnace transformer, electric welding transformer; Or used in electronic instruments and TV, radio and other power transformer of Shanghai hong - box transformer.
