Electric cable leakage detector

Electric cable leakage detectorNon contact detection is an important tool used in power emergency rescue to quickly locate power sources and prevent electric shock accidents. Based on the principle of electromagnetic induction, non-contact detection can detect AC leakage current within a safe distance range without direct contact with power sources or lines, avoiding the risk of electric shock. When the sound and light alarm approaches a power leakage, the device will emit a buzzing sound and flash the LED light. The alarm intensity increases with the distance, helping operators quickly locate the power leakage. Multi level sensitivity adjustment provides three modes: high, low sensitivity, and front concentrated detection (fine adjustment), adapting to different scene requirements. For example, high sensitivity is used for preliminary scanning of large areas, while low sensitivity is used for narrowing down the range and confirming specific locations. The self-test function is equipped with a built-in self-test circuit, which automatically performs a functional check after turning on the device to ensure its normal operation.

LDTC1 typeElectric cable leakage detectorIt is a new type of intelligent detector that integrates leakage detection, directional indicator light, and distress alarm. The leakage detection function can detect high and low voltage power sources in real-time in unknown environmental situations such as urban waterlogging rescue and earthquake rescue, and detect leakage signals to provide firefighters with a safer rescue environment. When firefighters are in danger, they can manually sound the alarm or the instrument will automatically sound the alarm. Quickly rescue firefighters in distress.

3、 Operation method

1. Power on and off; Press and hold the 'power' button for 3 seconds, and after a 'beep' sound, the screen will light up and the red directional light will turn on

Start up immediately. Press and hold the 'Power' button for 2 seconds to turn off the screen and directional lights, and the device will shut down.

2. Screen sleep mode; Lightly press the power button once while the screen is turned on to turn off. The orientation indicator light will continue to flash, and the screen will enter sleep mode. Or automatically enter sleep mode after 5 minutes of power on, and manually press the 'power button' to turn on the screen.

3. Leakage detection; In the power on state, the low detection mode (low sensitivity) is enabled by default. Press the 'Function' right button lightly, and the triangle on the screen will display 'High' to enter the high detection mode (high sensitivity). Press' Off 'again to temporarily turn off the detection function, and repeat the process. When approaching power lines or other sources (including situations where there is leakage in urban waterlogging and sewage), sound and green, yellow, and red three tone reminders will be used. As you gradually approach the power source, green will be displayed as a single tone continuous reminder for far distance, green and yellow will be displayed as dual tone continuous reminders for close distance, and green, yellow, and red will be displayed as four tone continuous reminders for close distance.

4. Manual alarm; Press the 'SOS' button lightly in the power on state to enter the strong alarm state, and the alarm display on the screen will show' strong alarm '. Press the 'SOS' button again to clear the alarm, and the screen will display' no alarm '.

5. Automatic alarm; After the detector is turned on, it enters the pre alarm working state after being stationary (30s ± 2S). During this period (30S ± 2S), a sufficient movement will cause the device to re-enter the previous standby mode and cancel the pre alarm state. If there is no movement within this period (30S ± 2S), the pre alarm will continue (15S ± 2S) before entering the strong alarm working state. During the pre alarm period (15S ± 2S), a sufficient movement will also cause the device to re-enter the previous standby mode and cancel the pre alarm state. If there is no mobile device within (30S ± 2S)+(15S ± 2S), it will enter a strong alarm working state. Pressing the 'SOS' button will cancel the strong alarm working state and return to standby mode.

6. High temperature alarm; After turning on the power of the detector, if the ambient temperature remains above 60 ℃ for 10 seconds, the detector will emit an alarm sound, indicating that the current ambient temperature is not suitable for personnel to stay and that evacuation or special protective measures need to be taken.

7. Empty call timing; Press and hold the 'SOS' button for 3 seconds when the device is turned on, and the detector will emit a' beep beep 'sound. If the' hour 'on the screen changes to' empty call ', it will enter the empty call timing state. Press and hold the' SOS' button again for 3 seconds, and if the 'empty call' on the screen changes to 'hour', the empty call timing will be released. The reminder method is to prompt once every 20 minutes, once every 25 minutes, and enter the strong alarm mode after 30 minutes to indicate the arrival of the timer time.
