Technical Field
[0001] This utility model relates to the field of high-voltage operation training technology, and in particular to a simulated high-voltage voltage testing device for teaching purposes. Background Technology
[0002] After a high-voltage equipment is de-energized, operators must perform a voltage detection procedure to ensure safety. This is a crucial step when working on high-voltage systems. The voltage detection procedure involves operators using a voltage detector to check the de-energized high-voltage equipment. If the equipment is energized, the voltage detector will emit an audible and visual alarm, indicating that the high-voltage equipment is still live.
[0003] To ensure the safety of workers, or due to limitations, voltage testing is typically demonstrated using simulations during high-voltage work training or recertification procedures. In these simulations, the entire process is conducted without electricity. The operator first tests the voltage at a simulated energized location, then tests at a de-energized location, and finally verifies the voltage at a simulated energized location.
[0004] This voltage testing method involves no contact with live electricity throughout the entire process, making it very safe for personnel. However, it lacks the audio-visual warnings and other elements of on-site voltage testing, failing to simulate a real voltage testing scenario and significantly reducing the effectiveness of the training.
[0005] Operating in such a fully simulated environment can easily lead to trainees not understanding the actual operating conditions under high voltage, which seriously affects the training effect and is not conducive to safe voltage testing operations under actual working conditions. Summary of the Invention
[0006] The technical problem to be solved by this utility model is a simulated high-voltage voltage testing device for teaching. This device overcomes the defects of traditional high-voltage voltage testing operation training, takes into account both high-voltage voltage testing audible and visual alarms and absolute safety of the operating environment, improves training effectiveness, and ensures safe voltage testing operations under actual working conditions.
[0007] To solve the above-mentioned technical problems, this utility model provides a teaching-grade simulated high-voltage voltage testing device, comprising a detector and a high-voltage simulator. The detector includes a battery, an audio-visual control circuit, a buzzer, an indicator light, and a normally open magnetic switch. The buzzer, indicator light, and normally open magnetic switch are respectively connected to the audio-visual control circuit, and the battery provides the operating power. The high-voltage simulator includes an insulator, a support rod, and a magnet. The support rod is located on the top surface of the insulator, and the magnet is located at the top of the support rod. When the normally open magnetic switch approaches the magnet, it is triggered to close, activating the audio-visual control circuit to control the buzzer to sound and the indicator light to illuminate.
[0008] Furthermore, the detector also includes a housing and a probe head. The probe head is located on the top surface of the housing. The battery, the sound and light control circuit, and the buzzer are located inside the housing. The indicator light is located on the panel of the housing. The normally open magnetic switch is located inside the probe head and is connected to the sound and light control circuit inside the housing via a wire.
[0009] Furthermore, the bottom surfaces of the housing and the insulator are respectively provided with internal threaded interfaces for connecting with external components.
[0010] Because this utility model's simulated high-voltage voltage testing device for teaching adopts the above-mentioned technical solution, namely, the device includes a detector and a high-voltage simulator, the detector includes a battery, an audio-visual control circuit, a buzzer, an indicator light, and a normally open magnetic switch, the buzzer, indicator light, and normally open magnetic switch are respectively connected to the audio-visual control circuit, and the battery provides working power; the high-voltage simulator includes an insulator, a support rod, and a magnet, the support rod is located on the top surface of the insulator, and the magnet is located at the top of the support rod; the normally open magnetic switch is triggered and closed when it is near the magnet, and the audio-visual control circuit is activated to control the buzzer to sound and the indicator light to light up. This device overcomes the shortcomings of traditional high-voltage voltage testing operation training, takes into account both high-voltage voltage testing audio-visual alarms and absolute safety of the operating environment, improves training effectiveness, and ensures safe voltage testing operations under actual working conditions. Attached Figure Description
[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the simulated high-voltage voltage testing device for teaching purposes according to this utility model. Detailed Implementation
[0012] Implementation, for example Figure 1 As shown, the teaching simulation high-voltage voltage testing device of this utility model includes a detector 1 and a high-voltage simulator 2. The detector 1 includes a battery 11, an audio-visual control circuit 12, a buzzer 13, an indicator light 14, and a normally open magnetic switch 15. The buzzer 13, indicator light 14, and normally open magnetic switch 15 are respectively connected to the audio-visual control circuit 12, and the battery 11 provides working power. The high-voltage simulator 2 includes an insulator 21, a support rod 22, and a magnet 23. The support rod 22 is located on the top surface of the insulator 21, and the magnet 23 is located at the top of the support rod 22. When the normally open magnetic switch 15 is close to the magnet 23, it is triggered to close, and the audio-visual control circuit 12 is activated to control the buzzer 13 to sound and the indicator light 14 to light up.
[0013] Preferably, the detector 1 further includes a housing 16 and a probe 17. The probe 17 is disposed on the top surface of the housing 16. The battery 11, the sound and light control circuit 12 and the buzzer 13 are disposed inside the housing 16. The indicator light 14 is disposed on the panel of the housing 16. The normally open magnetic switch 15 is disposed inside the probe 17 and is connected to the sound and light control circuit 12 inside the housing 16 via a wire.
[0014] Preferably, the bottom surfaces of the housing 16 and the insulator 21 are respectively provided with internal threaded interfaces 18 and 24 for connecting with external components.
[0015] This device balances both the audible and visual alarm for high-voltage detection and the absolute safety of the operating environment. The detector is powered by a 5V battery, and the high-voltage simulator is replaced by a strong magnet. A magnetic switch is used to start the detector, thereby activating the audible and visual alarm.
[0016] When this device is used in electrical testing operations during teaching and training, it can simulate the entire high-voltage electrical testing process. When testing a designated energized part, the detector can provide audible and visual alarms.
[0017] During actual training, the high-voltage simulator is installed in a fixed location via the internal thread interface at the bottom, and a high-voltage hazard sign is affixed to simulate the on-site working environment. The detector is installed on the high-voltage operating rod via the internal thread interface. The power switch of the detector is turned on, and the detector's probe head is slowly brought close to the high-voltage simulator while holding the high-voltage operating rod. The magnetic switch closes under the induction of the magnet in the high-voltage simulator, thereby controlling the buzzer to sound and the indicator light to light up through the sound and light control circuit, realizing the sound and light alarm for the voltage detection operation and completing the voltage detection operation training.
