Abstract
The utility model discloses a three-phase resistance furnace power and voltage capable of being adjusted. The three-phase resistance furnace comprises a resistance furnace body and a control cabinet for controlling the work of the resistance furnace body. A thyristor voltage and power adjusting unit for adjusting voltage and output power of the resistance furnace body is arranged in the control cabinet. According to the three-phase resistance furnace capable of adjusting power and voltage, the thyristor voltage and power adjusting unit is arranged in the control cabinet to control and adjust the output voltage of the resistance furnace body and further adjust the output power, so that the temperature in the resistance furnace body achieves a required temperature stably; and on and off times of a thyristor are reduced by changing the output power, and accordingly, interference with power grids is reduced, stabilities of the power grids are maintained, and not only the fine control of high temperatures can be improved, but also an energy conservation effect can be provided.
Description
Technical field
The utility model relates to a kind of resistance furnace, and concrete is the adjustable three-phase type resistance furnace of a kind of voltage and power.
Background technology
Existing three-phase type electric furnace, its temperature controlled principle is: reach control silicon controlled break-make purpose by temperature control display instrument control silicon controlled trigger voltage, thereby realize the control of temperature.
In real work, find, existing three-phase type electric furnace is when controllable silicon is switched on, namely be in the full power operation operating mode, furnace temperature can rise to fast and require temperature, and when reaching the requirement temperature, controllable silicon can carry out the switching electric current repeatedly frequently, cause very large fluctuation to disturb to electrical network, since be flat-out output, neither energy-conservation, also be unfavorable for the meticulous control of furnace temperature.
Given this, the utility model is intended to explore a kind of three-phase type resistance furnace of Power Regulation pressure regulation, and this three-phase type resistance furnace not only can be rapidly heated to requiring temperature, and can reduce the interference to electrical network, and energy-saving and cost-reducing.
Summary of the invention
The technical problems to be solved in the utility model is the three-phase type resistance furnace that proposes a kind of Power Regulation pressure regulation, and this this three-phase type resistance furnace not only can be rapidly heated to requiring temperature, and can reduce the interference to electrical network, and energy-saving and cost-reducing.
Realize above-mentioned technical purpose, the three-phase type resistance furnace of Power Regulation pressure regulation of the present utility model, comprise the resistance furnace body and be used for controlling the switch board of described this body running of resistance furnace, be provided with in the described switch board be used to the silicon-controlled voltage regulation power regulating eqiupment of regulating described resistance furnace bulk voltage and power output.
The beneficial effects of the utility model are:
The three-phase type resistance furnace of Power Regulation pressure regulation of the present utility model, by the silicon-controlled voltage regulation power regulating eqiupment is set in switch board, output voltage to the resistance furnace body controls to adjust, and reaches the adjusting of power output, makes the intrinsic temperature of resistance furnace steadily reach the requirement temperature, by changing power output, reduce controllable silicon break-make number of times, and then reduce the interference to electrical network, safeguard that it is stable, the meticulous control of temperature can be improved, energy-conservation effect can be played again.
Description of drawings
Fig. 1 is the structural representation of the three-phase type resistance furnace embodiment of the utility model Power Regulation pressure regulation.
The specific embodiment
As shown in Figure 1, be the structural representation of the three-phase type resistance furnace embodiment of the utility model Power Regulation pressure regulation.The three-phase type resistance furnace of the Power Regulation pressure regulation of present embodiment comprises resistance furnace body 1 and is used for the switch board 2 that controlling resistance furnace body 1 is worked, and is provided with in the switch board 2 be used to the silicon-controlled voltage regulation power regulating eqiupment 3 of regulating described resistance furnace body 1 voltage and power output.
The three-phase type resistance furnace of the Power Regulation pressure regulation of present embodiment, by silicon-controlled voltage regulation power regulating eqiupment 3 is set in switch board, output voltage to resistance furnace body 1 controls to adjust, and reaches the adjusting of power output, makes the temperature of resistance furnace body 1 steadily reach the requirement temperature, by changing power output, reduce controllable silicon break-make number of times, and then reduce the interference to electrical network, safeguard that it is stable, the meticulous control of temperature can be improved, energy-conservation effect can be played again.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
