Description

Technical Field

[0001] The utility model relates to the field of power system equipment, in particular to a power system simulation device for demonstration. Background Art

[0002] The power system simulation equipment allows operators to simulate and control the power system in the power system cabinet through a demonstration console to achieve real-time practice of various work processes and emergency measures of the power system. Although the power system in the power system cabinet has anti-short-circuit protection measures, operators are prone to frequent misoperations during long-term practice, causing local components of the power system in the power system cabinet to overheat. At this time, if the power system cabinet has poor ventilation and poor heat dissipation, it is easy to cause fire. If the fire in the power system cabinet is not extinguished in time, it will eventually cause a fire in the power system cabinet, causing serious losses. Utility Model Content

[0003] In order to overcome the disadvantage that the power system of the power system simulation device may cause ignition due to frequent misoperation, thereby easily causing fire, the utility model provides a power system simulation device for demonstration.

[0004] A power system simulation device for demonstration includes a power system cabinet, a fan, a demonstration operating table, a gate, a thermal fuse, and a fire powder capsule; a heat dissipation slot structure is provided on the power system cabinet; a fan aligned with the heat dissipation slot is installed on the power system cabinet; a demonstration operating table is installed on the power system cabinet; a gate is slidably connected to the heat dissipation slot of the power system cabinet; a thermal fuse is fixedly connected between the gate and the power system cabinet; a fire powder capsule is placed on the fan, the fire powder capsule is filled with fire powder, and the fire powder capsule is aligned with the gate in upper and lower directions.

[0005] As an improvement to the above solution, a fire alarm light is installed on the power system cabinet to monitor whether there is a fire in the power system cabinet.

[0006] As an improvement to the above solution, a baffle is fixedly connected to the fan.

[0007] As an improvement to the above solution, a gate knife is fixed to the inner bottom of the gate.

[0008] As an improvement to the above solution, an electric push rod is installed on the power system cabinet; the telescopic end of the electric push rod is fixedly connected to the telescopic rod; and the telescopic end of the telescopic rod is fixedly connected to the gate.

[0009] As an improvement to the above solution, an emergency button for controlling the operation of the electric push rod is installed on the demonstration console.

[0010] The utility model has the following advantages: the utility model describes an electric power system simulation device for demonstration, the heat dissipation slot of the electric power system cabinet is equipped with a fan for promoting heat dissipation and ventilation, the fan is provided with a baffle and a fire-fighting powder capsule, the fire-fighting powder capsule is filled with fire-fighting powder, and the heat dissipation slot of the electric power system cabinet is also provided with a gate, which is fixed to the heat dissipation slot by a thermal fuse. When ignition occurs in the electric power system cabinet, the thermal fuse will be burned, thereby triggering the gate to close downward in time, and at the same time, the falling gate causes the fire-fighting powder in the fire-fighting powder capsule to explode, allowing the fire-fighting powder to be sprayed into the electric power system cabinet with the air flow blown out by the fan, so as to extinguish the ignition in time and avoid the expansion of the ignition range; it effectively overcomes the disadvantage that the electric power system of the electric power system simulation device is in danger of causing ignition due to frequent misoperation, thereby causing easy fire.

[0016] Example

[0017] A power system simulation device used for demonstration, such as Figure 1-Figure 3As shown, it includes a power system cabinet 1, a fan 12, a demonstration operating table 2, a gate 3, a thermal fuse 4, and a fire powder capsule 5; a fire alarm light 11 is installed on the power system cabinet 1; a heat dissipation slot 101 structure is opened on the power system cabinet 1; a fan 12 aligned with the heat dissipation slot 101 is installed on the power system cabinet 1; a baffle 121 is welded on the fan 12; a demonstration operating table 2 is installed on the front side of the power system cabinet 1; a gate 3 is slidably connected to the heat dissipation slot 101 of the power system cabinet 1; a thermal fuse 4 is fixed between the gate 3 and the power system cabinet 1, and the gate 3 is initially fixed to the upper side of the heat dissipation slot 101 by the thermal fuse 4; a fire powder capsule 5 is placed on the fan 12, and the fire powder capsule 5 is filled with fire powder, and the fire powder capsule 5 is aligned with the gate 3 up and down; a gate knife 31 is fixed to the inner bottom of the gate 3.

[0018] like Figure 1-Figure 3 As shown, an electric push rod 32 is installed on the power system cabinet 1; the telescopic end of the electric push rod 32 is fixedly connected to the telescopic rod 33; the telescopic end of the telescopic rod 33 is fixedly connected to the gate 3; and an emergency button 21 for controlling the operation of the electric push rod 32 is installed on the demonstration operating table 2.

[0019] The utility model is a power system simulation device for demonstration. The operator performs various specified operation exercises on the power system in the power system cabinet 1 through the demonstration operation table 2. At this time, the gate 3 is located above the heat dissipation slot 101, so that the heat dissipation slot 101 is in an open state. The fan 12 blows fresh air from the outside into the power system cabinet 1 through the heat dissipation slot 101, and performs efficient heat dissipation work in the power system cabinet 1, thereby reducing overheating of components in the power system cabinet 1.

[0020] When the power system cabinet 1 is severely overheated and ignites, the fire alarm light 11 will recognize the ignition and quickly sound an alarm, and the high-temperature heat radiation in the power system cabinet 1 will burn the thermal fuse 4 in the first time. At this time, after the gate 3 loses the restraint from the thermal fuse 4, the gate 3 drives the telescopic rod 33 to fall rapidly under its own gravity, and the gate 3 blocks most of the heat dissipation groove 101 to prevent the outside air from entering the power system cabinet 1 through the heat dissipation groove 101. At the same time, the falling gate 3 squeezes the fire powder capsule 5 through the gate knife 31, causing the fire powder in the fire powder capsule 5 to explode. The baffle 121 effectively intercepts most of the exploded fire powder in the heat dissipation groove 101 to prevent a large amount of fire powder from being emitted into the outside air. At the same time, the fan 12 pumps the exploded fire powder into the power system cabinet 1, and the fire powder is used to extinguish the ignition in the power system cabinet 1 in time to prevent the scope of ignition from expanding.

[0021] When a fire occurs in the power system cabinet 1 but the thermal fuse 4 is not successfully burned, the operator only needs to quickly press the emergency button 21. The emergency button 21 will send a start signal to the electric push rod 32 through the circuit system, allowing the electric push rod 32 to push the gate 3 down through the telescopic rod 33. At the same time, the gate 3 will actively break the thermal fuse 4, and the fire in the power system cabinet 1 will be extinguished according to the above steps.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
