The electrolyzer control power source special cabinet of Germany Schneider company is exactly the electrolyzer control power source special cabinet that can satisfy the Electrolytic Workshop particular requirement.This power cabinet comprises that primary source inlet wire branch road, standby power supply inlet wire branch road, system selector switch, current transformer, over-pressure safety device, isolating switch, isolating transformer, switchgroup, electric-leakage detection circuit and dual power supply throw device mutually.The setting that this dual power supply is thrown device mutually is in order to guarantee when main power circuit cuts off the power supply to automatically switch and power in the standby power supply loop.Because its circuit structure complexity, cost is higher, can not satisfy the needs of domestic aluminum electrolysis industry.
The structure of domestic all related products all is to adopt for the particular requirement of satisfying the aluminium industry production to convert the AC380V power supply to AC220V through isolating transformer in cabinet, as the mode of control power supply.
Summary of the invention
Task of the present utility model be design a kind of simple in structure, cost is low, be easy to the electrolyzer control power source special cabinet producing, keep in repair.
The utility model is with reference to the constitutional features of similar products at home and abroad; new organization plan of the present utility model has been proposed; this electrolyzer control power source special cabinet comprises primary source inlet wire branch road; standby power supply inlet wire branch road; system selector switch; current transformer; over-pressure safety device; isolating switch; isolating transformer; switchgroup; electric-leakage detection circuit and dual power supply are thrown device mutually; it is characterized in that dual power supply throws device mutually and be made of a Relay-controlled Circuit; rly. normally closed contact on the primary source inlet wire branch road is connected with the relay1 coil on the standby power supply inlet wire branch road, and the rly. normally closed contact on the standby power supply inlet wire branch road is connected with the relay1 coil on the primary source inlet wire branch road.
In order to make this electrolyzer control power source special cabinet can guarantee that power supply system is safer, the utility model also has electric-leakage detection circuit.This circuit is made of current transformer, leakage relay, pilot lamp, press button and system selector switch, two pairs of contacts of leakage relay are connected with the corresponding contact of current transformer on primary source inlet wire branch road and the standby power supply inlet wire branch road respectively, and the normally opened contact of leakage relay is connected with pilot lamp with press button and after connecing again.Its principle of work is an operating selection switch, and when electric power incoming line leaked electricity, current transformer produced electric current, the leakage relay action, its normally opened contact closure, signal lamp is bright,, operate each system selector switch this moment respectively,, making it to reset, pilot lamp is also bright, is this correspondence branch road electric leakage with regard to decidable.Press the button switch, can check the quality of signal lamp.
Dual power supply in this electrolyzer control power source special cabinet is thrown the simple Relay-controlled Circuit of device utilization mutually, solved the deficiency of at present domestic and international aluminium industry electrolysis power supply technique related products safe, reliable and effectively, also increased the detection of electrical leakage function simultaneously, the Aluminium Electrolysis safe power supply is reliably guaranteed.Compare with similar products at home and abroad, have simple in structurely, cost is low, and remarkable advantage has for ease of maintenaince satisfied the particular requirement of aluminum electrolysis industry power supply, has saved a large amount of foreign exchanges to country.Use by reality, it is quite satisfied that feedback information makes us.
