Abstract
The utility model provides a cabinet of a low-voltage reactive compensation device of a ferroalloy electric furnace, and relates to the technical field of smelting. The technical problems that the traditional cabinet of the low-voltage reactive compensation device of the ferroalloy electric furnace is heated severely, influence of eddy current heating on the cabinet is high, and the like are solved. A cabinet body (6) of the cabinet of the low-voltage reactive compensation device of the ferroalloy electric furnace is hollow and rectangular, and is provided with four layers of supporting pieces (7) from bottom to top, wherein capacitors (1) and electric reactors (3) are fixedly arranged on the first layer of supporting pieces and the fourth layer of supporting pieces through connectors; fuses (2) and contactors (4) are fixedly arranged on the second layer of supporting pieces and the third layer of supporting pieces through connectors; water inlets and water outlets of water-cooled copper tubes (5) are formed between the second layer of supporting pieces and the third layer of supporting pieces; and the cabinet body (6), the supporting pieces and the connectors are made of stainless steel materials.
Description
Technical field
The utility model patent relates to technical field of smelting, particularly a kind of cabinet of iron alloy electric furnace low-voltage reactive compensator capable.
Background technology
General common cold-rolled steel sheet, the carbon steels etc. of adopting of iron alloy electric furnace low-voltage compensation apparatus are made cabinet, strutting piece and installed part; Because iron alloy electric furnace majority self power factor is all lower, especially large capacity iron alloy electric furnace, only be about 0.75 as the mineral hot furnace more than the 1650OKVA self power factor, and often there is the situation of super 20-50% load to occur, therefore its compensation capacity is generally all larger, and compensation circuit self electric current also is amperes up to ten thousand like this.Because the iron alloy electric furnace load is generally larger, power factor (PF) is lower, required reactive compensation capacity is also larger, the electric current of low-voltage reactive compensator capable also is very large like this, high-current conductor produces very strong alternating magnetic field, and cabinet, strutting piece and installed part that near cold-rolled steel sheet, carbon steel are made will form very large eddy current, and cabinet seriously generates heat, affect the electric component useful life in the compensation arrangement, increase electric energy loss.
Can solve the heat radiation except adopting the water-cooled copper bus to connect, a large amount of cabinets that capacitor is installed all adopt cold-rolled steel sheet to make, the large electric current formed eddy-current heating impact of thousands of peaces flow through of cabinet top is also very large like this, will greatly accelerate the ageing of insulation of cabinet inner capacitor etc.
Summary of the invention
The technical problems such as the cabinet that the utility model is intended to solve conventional iron alloy electric stove low-voltage reactive compensator seriously generates heat, the eddy-current heating impact is very large are effectively avoided eddy-current heating to provide a kind of, are prolonged the cabinet of the iron alloy electric furnace low-voltage reactive compensator capable in compensation arrangement useful life.
The purpose of this utility model is achieved through the following technical solutions.
The cabinet of iron alloy electric furnace low-voltage reactive compensator capable of the present utility model, cabinet 6 is the rectangle of hollow, have from bottom to top four layers of strutting piece 7, be installed with capacitor 1 and reactor 3 by connector on first and the 4th layer of strutting piece, be installed with fuse 2 and contactor 4 by connector on second and the 3rd layer of strutting piece, the intake-outlet of water-cooled copper 5 is located between second and the 3rd layer of strutting piece, and aforesaid cabinet 6, strutting piece and connector are stainless steel material.
The beneficial effect of the cabinet of the utility model iron alloy electric furnace low-voltage reactive compensator capable: can effectively cut off the eddy current loop, can reduce the heating situation that eddy current causes, in the useful life of extension fixture electric component, reduce electric energy loss.
Description of drawings
Fig. 1 is structural representation of the present utility model
The number in the figure explanation:
1 capacitor, 2 fuses, 3 reactors, 4 contactors, 5 water-cooled coppers, 6 cabinets, 7 strutting pieces
Embodiment
The utility model detailed construction, application principle, effect and effect with reference to accompanying drawing 1, are explained by following execution mode.
The cabinet of iron alloy electric furnace low-voltage reactive compensator capable of the present utility model shown in Fig. 1, cabinet 6 is the rectangle of hollow, have from bottom to top four layers of strutting piece 7, be installed with capacitor 1 and reactor 3 by connector on first and the 4th layer of strutting piece, be installed with fuse 2 and contactor 4 by connector on second and the 3rd layer of strutting piece, the intake-outlet of water-cooled copper 5 is located between second and the 3rd layer of strutting piece, and aforesaid cabinet 6, strutting piece and connector are stainless steel material.
Because cabinet 6, strutting piece and connector are stainless steel material, can cut off the eddy current loop; In addition, owing to adopted four-layer structure, can further reduce the heating situation that eddy current causes.In cabinet, increase water-cooled copper, play the effect in the useful life of reducing cabinet temperature, extension fixture electric component, and reduce electric energy loss.
In sum; the cabinet of iron alloy electric furnace low-voltage reactive compensator capable of the present utility model has can effectively cut off the eddy current loop; can reduce the heating situation that eddy current causes; the useful life of extension fixture electric component; reduce the technological merits such as electric energy loss, can be widely used in the protection of iron alloy electric furnace low-voltage compensation apparatus.
