Description

Technical Field

[0001] The present application relates to the field of iron and steel metallurgy technology, and in particular to an early warning device for iron and steel metallurgy electrical control equipment. Background Art

[0002] In metallurgical work, since the working process temperature is high and there are many precision instruments, it is necessary to use early warning devices to monitor the work content, instrument operating parameters and electrical equipment to avoid dangers in the work that may cause damage to workers or equipment.

[0003] In addition, the existing Chinese patent publication number CN216412300U discloses an early warning device for electrical control equipment for steel metallurgy, including a shell, a distribution box is provided at the lower end of the shell, a voltage transformer is provided at the lower end of the shell along one side of the inner wall, a current transformer is provided on the inner wall of the shell, a residual current transformer is provided on the inner wall of the shell, a line inlet is provided at the lower end of the shell, a signal conditioning circuit is provided on the inner wall of the shell, a control box is provided above the signal conditioning circuit, and a circuit breaker is provided at the upper end of the control box. A buzzer is provided on one side of the inner wall of the shell, a warning light is provided on one side of the top of the shell, a signal transmitter is provided on the other side of the shell, and an outlet is provided at the upper end of the shell.

[0004] The various detection devices of the above patents are all installed in a shell, and most of the devices are in a high-temperature environment. Most of the detection devices do not have an independent heat dissipation function and can only dissipate heat through the ventilation windows on the shell. In addition, the detection equipment itself will also generate heat. The detection equipment is in a high-temperature or even ultra-high-temperature environment for a long time, which will lead to unstable performance of the detection equipment. If things go on like this for a long time, it will easily cause damage to the equipment. Therefore, it is necessary to add a cooling device to the detection equipment. Coolant is a commonly used cooling material in the cooling device. Since the evaporation rate of the coolant is related to the temperature, pressure and properties of the coolant, the higher the temperature, the more intense the evaporation. When the coolant content in the heat dissipation device is reduced after long-term use, it will affect the overall heat dissipation effect of the equipment. For this reason, this scheme proposes an early warning device for steel and metallurgical electrical control equipment. Utility Model Content

[0030] The implementation principle of the early warning device for steel metallurgical electrical control equipment in the embodiment of the present application is as follows: first, the signal conditioner 10, the voltage transformer 11, the current transformer 12 and the residual current transformer 13 are installed on the cooling plate 5 in sequence, and then the heat conductive block 7 is installed on the cooling plate 5, so that each detection device can directly or indirectly contact the cooling plate 5, thereby cooling the entire detection device and reducing the impact of the high temperature environment on the equipment, and then the alarm light 16, the signal transmitter 17 and the buzzer 21 are installed on the box body 15 in sequence, and then the cooling box 1 is attached to the back of the box body 15, and then the fixing piece 1505 is threadedly installed on the box body 15, and under the action of the positioning block 2, the cooling box 1 can be fixedly installed on the back of the box body 15. Then, after the lines are connected, the box 15 is fixed to the wall with bolts. By setting the alarm value on the controller 8, when the metallurgical equipment is running, the circuit passes through the voltage transformer 11, the current transformer 12, and the residual current transformer 13. The weak electrical signals output by the sensors on the voltage transformer 11, the current transformer 12, and the residual current transformer 13 are amplified by the signal conditioning circuit on the signal conditioner 10, and the voltage, current, and residual current data in the equipment are displayed on the display of the controller 8. When the voltage, current or residual current inside the equipment is too large and exceeds the warning value of the controller 8, the controller 8 will control the circuit breaker 14 to disconnect, so that the equipment is powered off to avoid accidents. At the same time, the controller 8 will start The alarm light 16 and the buzzer 21 can send out early warning signals in time to remind workers. At the same time, the controller 8 will send an alarm signal to the management department through the signal transmitter 17, so that maintenance can be carried out in time. Since the cooling plate 5 is welded on the cooling 1, when the above-mentioned multiple detection equipment is in operation, the high temperature generated at the same time will be transmitted to the liquid storage chamber A101 in the cooling box 1 through the cooling plate 5. The transmitted high temperature will heat the coolant in the liquid storage chamber A101, causing the coolant to vaporize and evaporate. The vaporized coolant will be located in the upper part of the liquid storage chamber A101. After contacting the capillary 108 with a lower temperature in the upper part of the liquid storage chamber A101, it will be liquefied into liquid and flow back to the liquid storage chamber A101 through the capillaries 108 on both sides. In the coolant at the bottom of 101, heat will be consumed in this process, thereby realizing the reflux of the coolant and the circulation of the working medium, thereby achieving the effect of cooling the coolant. The cooling plate 5 can be completely immersed in the propylene glycol coolant inside the liquid storage chamber A101. When the ethylene glycol coolant in the liquid storage chamber A101 and the liquid storage chamber B102 evaporates due to the high temperature environment and causes the liquid level to drop, the internal coolant will evaporate with the high temperature and the floating block 105 will drop with the liquid level, thereby driving the limiting column 106, the lifting plate 104 and the sealing ring 107 to drop, so that the limiting column 106 is separated from the leak hole 103, so that the remaining propylene glycol coolant in the top liquid storage chamber B102 will be quickly replenished to the liquid storage chamber A101. When the liquid level is restored,The floating block 105 is affected by the buoyancy and drives the limiting column 106, the lifting plate 104 and the sealing ring 107 to rise. Under the action of the limiting column 106 and the sealing ring 107, the leak hole 103 is blocked, thereby ensuring that the coolant level in the liquid storage chamber A101 is always maintained at the same standard, thereby ensuring that the heat dissipation effect of the cooling device is not reduced.

[0031] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
