Transformer oil conservator oil level detection rod based on ultrasonic waves

A transformer oil conservator oil level detection rod based on ultrasonic waves relates to the technical field of transformer maintenance auxiliary equipment, a detector is fixedly connected to a ball head, the ball head is connected with an insulating telescopic rod (3), a wireless communication module A is arranged in the lower portion of the insulating telescopic rod, the outer portion of the insulating telescopic rod is connected with a remote control button, and a grab handle is arranged at the lower end of the insulating telescopic rod; an ultrasonic sensor, a wireless communication module B and a buzzer are arranged on the detector, the wireless communication module B is in control connection with the ultrasonic sensor, and the ultrasonic sensor is connected with the buzzer through a circuit. The beneficial effects of the utility model are that the device is small in size, light and convenient to carry and use, and the buzzer device is adopted, so that fixed-point detection can be realized, and different-point continuous detection can be carried out; compared with infrared, laser or other radioactivity detection modes, protection is not needed, the influence of light and environmental media is avoided, and the cost is low.
