1 easy to operate, 2 work steadiy and reliably, 3 faster protection, etc... - details see: https://www.machineto.com/mechinery-for-casting-company-made-in-china-electric-furnace-10159353

Mainly used in smelting steel, iron, copper, aluminum and alloy, high efficiency and power saving with fusion effect is good, metal components uniform, burning less, temperature rise is fast and the temperature is easy to control and so on characteristics, suitable for all kinds of metal melting occasion.

A brief introduction of characteristic, control technology

1 for the parallel inverter research and development of the fifth generation of intelligent controller, has been widely used in various metal smelting, heat insulation and equipment for induction heating power supply control.

The 2 controller is a single plate integrated control panel, digital trigger, has high reliability, high accuracy and easy debugging, less element relay.

3 advanced frequency sweep type class it stimulated, zero voltage starting technology, start a 100% success rate.

The 4 inverter control reference the United States ( ABB, pillar, Ajax ) company, Fuji Electric of Japan and other foreign advanced control technology.

To the development of the inverter control technology, has a very strong anti interference ability.

5 automatic follow the load changes, when running with a non fault of automatic restart function and power automatic regulation function.

6 has the ideal current limit, limit pressure, specific time or turn-off angle inverter control, ensure the reliable operation of the equipment.

7 with perfect multi-level protection system (pressure, lack of phase, under-voltage, over-voltage, over-current, turn-off time, straight, interlocked operation etc.).

8 has higher conversion efficiency of 1000 and below Hz greater than 96%.

Brief introduction

2.1 the device on the installation base without special requirements, but the installation environment should refer to the device using condition selection. For ease of maintenance, the cabinet and the surrounding walls should be more than 1m from the cabinet door can be conveniently opened, in order to ensure.

2.2 the device of three-phase power supply line and into the intermediate frequency output line, from the cabinet bottom cable trench entry. Conductor cross section according to capacity with reference to the device technology data selection, all wire connection, should maintain good contact.

2.3 the equipment cabinet base grounding bolt, the installation must pay attention to good grounding.

2.4 KGPS frequency converter cooling system water pipe diameter is generally 1.5 to 2 inches, open cooling water pipe diameter should be slightly larger than the diameter of the water pipeline; closed cooling system, the same diameter water pipelines. On sewer, from outside the tank ditch is introduced, and manifold connection; water supply pressure is greater than or equal to 0.12Mpa.

2.5 in general, load and the frequency conversion cabinet mounted closer the better, should not exceed 15m, to reduce the line loss, so that the load obtains the maximum power.

2.6 power supply cooling water device, in principle should be used in pure water device, no pure water device, appropriate to increase the water flow rate, power above 800KW equipment, shall be equipped with the appropriate volume of water cooling device.

Two, use:

Thyristor frequency converter, is a three phase alternating current energy into single-phase intermediate frequency electric energy of static frequency converter. The device adopts the parallel inverter circuit, thus the load adaptability is stronger, can be used as induction heating, smelting, quenching and other equipment for induction heating power supply.

Three: Common KGPS series frequency converter reference data

The operation is simple, applicable to all kinds of casting process.
