Power Supply Yinda Induction Furnace
The central control circuit board of IF power cabinet is optimized by computer, and the unit circuit has stable performance, reliable quality and strong anti-interference.
The IF power supply cabinet has the following characteristics:
1.The central control circuit board is optimized and designed by the computer, and the unit circuit is optimized and combined, and the device has a stable performance, reliable quality and strong anti-interference;
2 Reasonable coordination and convenient maintenance;
3.On the basis of zero pressure start, the automatic sweep repeat start function is added, the voltage and current ring circuit are closely tracked, and the equipment starts and stops
Smooth and stable, without current impact.
4.The inverter start signal adopts a single signal highly sensitive trigger circuit, which further increases the starting performance of the equipment;
5.Constant power circuit control system, in the production with the change of the furnace material quickly the voltage and current automatic regulation in the best setting, do not need to manually adjust the inverter cut Angle;
6.There are perfect overpressure, overcurrent, underpressure, water shortage, phase deficiency, pressure and current limit and other protection systems, so as to ensure the reliability and stability of the equipment;
7.Highly integrated circuit scheme, debugging and operation are fast, simple, easy to learn.
Medium frequency power cabinet main circuit usesrectifying series form, the less harmonic wave content, good flow characteristics.The two main patent technology is: double isolation electric rectifier controlled pulse extension circuit (patent no. : 201420280539.2) and the expansion of double isolation optical pulse rectifier circuit (patent no. : 201410232415.1).One power cabinet use one main control board only without any other auxiliary board,highly intergrated and easy for changing.Air flowing equipment should be added to the cabinet, so that the cabinet can close the door when it is working to protect dusty.The temperature Of cabinet should be as the same as desigend data to ensure work properly.
The main protection function
- The lack fault phase protection of main circuit phase, three-phase imbalance protection；
- Rectifier bridge imbalanceworking protection；
- Low voltage protection of power grid；
- Perfect and reliable current limiting (intercepting), pressure limiting (section pressure) protection；
- Over current protection - any time more than current setting value, implement over current protection；
- Over-voltage protection - any time over voltage setting value, implementation of over-voltage protection；
- Low voltage protection of Controlpower supply.
- Low Frequency protection；
- Corresponding fault display function.
- Medium frequency power supply control circuit adopts the fully integrated circuit,of which two main patent technology is: an active high voltage electronic transformer (patent no. : 201420280467.1), and an active high voltage electronic transformer (patent no. : 201410232377 X).
MF power supply cabinet 01
Power cupboard of the circuit breaker uses domestic well-known manufacturers of vacuum circuit breaker, completely solves the problem of the ordinary air circuit breaker, arc strike a light.Power circulating water with no carbon contained in the hose connection, than common enhancement conduit with high temperature resistance, resistance to electric wheel hot shot, the bend better sexual characteristics, greatly increase its service life.
