Description
Technical Field
The utility model relates to an electric power tech field especially relates to a test fastener with alarm device.
Background
Because the current transformer substation grounding downlead conduction test has a very long test wire, often more than 50 meters, leads to that the wiring personnel and instrument operating personnel can not effectual communication, has that the wiring personnel mistake bumps electrified test fastener, and the risk of electrocuteeing. The existing test alarm wire clamp mainly adopts an induction warning device, and the main principle is electromagnetic induction, and the LED and the buzzer are controlled to give out prompts after receiving, filtering and amplifying by an antenna depending on a variable magnetic field generated by alternating current. The utility model discloses mainly report to the police to the detection of direct current.
Disclosure of Invention
To the not enough of prior art, the utility model provides a test fastener with alarm device, its characterized in that: two handles of the test wire clamp are connected with a voltage wire, the other handle is connected with a current wire, a Hall sensor module, a buzzer and a button cell are arranged inside the handle of the current wire, one pin of the Hall sensor module is connected with the anode of the button cell, the other pin of the Hall sensor module is connected with the cathode of the button cell and the cathode of the buzzer, the anode of the buzzer is connected with the third pin of the Hall sensor module, and the Hall sensor module is connected in series with the current wire.
The Hall sensor module is characterized by being of an ACS758KCB-100B type, the highest current capacity of 100A, the highest working voltage of 6V of a secondary terminal, the output voltage of one half of the input voltage and the response time of 30 uS. The thickness is about 15mm, the length is 20mm, and the width is 15 mm.
The buzzer is an active buzzer with working voltage of 2.5V-3.5V, the diameter is 12mm, and the height is 9.5 mm.
The two sections of the button cell have the output voltage of 3V, the diameter of 20mm and the thickness of 1.5 mm.
The utility model discloses a use method: the test wire clamp is clamped on a tested wire, the test wire is powered on after the instrument is switched on, the buzzer located inside the handle of the test wire clamp gives an alarm to remind a user to touch the test wire clamp, and the alarm is automatically released after the instrument is powered off.
The beneficial effects of the utility model reside in that: the electric shock caused by mistakenly touching the test wire clamp with the point is prevented, the safety risk of field wiring personnel is further reduced, the structure is simple, the purchase is cheap, and the safety and the practicability are realized.
