Abstract

The utility model relates to an anti-theft ring for wires and cables, which is designed aiming at the case that the facilities, such as transformers, the wires and the cables erected on the field for the electricity supply and the communication are frequently stolen. The utility model is characterized in that the utility model utilizes the principle of the electric shock; the anti-theft ring for wires and cables is composed of three parts, and alternative current and direct current lines are arranged in the anti-theft ring for wires and cables to be used for automatically controlling the time when electrify is switched on or switched off. The purpose of the utility model is to cause the conventional inactive prevention to be changed into the positive prevention to contact any part of a thief to enable the thief to generate the mental fear to prevent the thief from climbing a pole to carry out theft; the safety application of the wires and the cables can be effectively protected.

Description

Anti-theft ring for wire and cable

The utility model relates to that open-air electric wire, electricity are pulled, the anti-theft ring of transformer.

According to public security and news department, be erected at facilities such as open-air electric wire, electricity are pulled, transformer, being cut stolen case often has generation, does great damage for industrial and agricultural production and liaison, and political fallout and economic loss are very big.In the past for a long time, can only be passive the strick precaution to this measure of taking, as spend to employ the people to nurse, device alarm buzzer and so on, its result is hard to guard against.

The purpose of this utility model is to become passive the strick precaution and is active prevention, and a kind of more effective and reliable desirable alarm is provided.

The purpose of this utility model is achieved in that two kinds of anti-theft ring of concrete minute AC and DC, uses the electric shock principle, touches any position of robber, causes psychology to be feared, and stops pole-climbing to be committed theft.Its technical characterictic is:

(1) profile of anti-theft ring is a ring-type, is made of retainer ring, electric shock ring and electric shock pin.

(2) inside components of direct current anti-theft ring has: the time relay, automatic switch, triode, resistance, transformer, diode, capacitor.Its circuit block-diagram is:

(3) inside components of alternating current anti-theft ring has: the time relay, automatic switch.Its circuit block-diagram is:

The utility model anti-theft ring is installed on the electric pole, and height is apart from more than the 8m of ground, and 50cm place below anti-theft ring marks and draws warning line (red line that 10cm is wide).For ease of installing, anti-theft ring is divided two semicircles, by screw.New stringing road can be inserted in from the top of electric pole; The stringing road can be stuck in two semicircles on the electric pole, is screwed then.In order to reduce power consumption, be convenient to change and overhaul circuit, ensure electrical safety, the electric current of anti-theft ring should be the outage on daytime by the time relay and automatic switch control usually, energising at night (also can adjust the conduction time of cutting off the power supply according to actual needs).

Generally, during by electric current 50 milliamperes (0.05A), the center nerve can be compromised in the human body, and heart stops to beat and dead.So the interchange safe voltage of regulation is below 36V.The utility model direct current anti-theft ring is directly pulled with electricity and is connected, and the voltage that the communication electricity is pulled is 60V, 48V, 36V, although can produce 20KV pulse voltage up and down, because of power is little, can only make the Palestinian Popular Front for the Liberation of Palestine (PFLP) fiber crops, loses steadily, can wounded or disabledly not cause death; The alternating current anti-theft ring directly is connected with electric wire, and the rated voltage of production and illumination electric wire is 11KV, 6KV, 380V, 220V, and power is big again, so danger close, one touches promptly extremely.

Claims

1, utility model electric wire AC and DC electricity anti-theft ring, technical characterictic is that its profile is a ring-type, is made of retainer ring, electric shock ring and electric shock pin.

2, described according to claim 1, the direct current anti-theft ring is characterised in that circuit is: power supply → time relay → automatic switch → triode → resistance → transformer → diode → capacitor → electric shock ring (pin).
