Abstract
Insulators which are arranged on high voltage lines arranged on a steel tower lose insulating property because of fouling, lightning stroke and other reasons, so the high voltage lines generate easily a fault of short circuit to the steel tower, besides, the positions of the faults can not be judged, so the repair work is time-consuming, arduous and of a great loss. The utility model provides an alarm capable of indicating accurately the positions of the faults, and the utility model is composed of a box body which is suspended on the high voltage lines and an alarm circuit which is arranged in the box body. The utility model is characterized in that a connecting line of the insulators arranged on the high voltage lines is sheathed with an annular iron core coil, both ends of the annular iron core coil are connected with a rectifying circuit, and the output end of the annular iron core coil is connected with a delaying control switch of connection time, an electric detonator and a short circuit mark flag, or connected with a radio transmitter of short circuit signals. The utility model has the advantages of simple structure, convenient installation and accurate alarm.
Description
The utility model relates to a kind of warning device, definitely says so to relate to a kind ofly can obviously indicate thunder and lightning or other reason, causes one or the several hi-line warning device to the short circuit of grade iron tower.
Be equipped with on the iron tower of high voltage transmission line at present, although lightning protection all is housed, but still can not avoid the destruction of being struck by lightning fully, thunderbolt and the stained insulator short circuit that tends to make between high voltage transmission line and iron tower, cause the short trouble of hi-line to iron tower, because can not the intuitive judgment abort situation, just must pursue root step by step during reparation and check, time-consuming, effort, maintenance cost height, economic loss is big.
The purpose of this utility model is: overcome above-mentioned shortcoming, for the user provides a kind of iron tower high voltage transmission line short-circuit alarming device that can obviously indicate the short trouble position.The purpose of this utility model realizes by implementing following technical proposals: be installed in the iron tower high voltage transmission line short-circuit alarming device between pylon and high voltage transmission line insulator; by having the box body of sealing up a door; and the warning circuit that is contained in the box body is formed; it is characterized in that: this warning circuit is by being sleeved on an annular core on the metal connecting line between pylon and high voltage transmission line insulator; be wrapped in an electromagnetic induction coil on the annular core; two ends at this coil connect a rectification circuit; its output terminal passes through over-voltage protection element; the signal limiter element tie-time postpones gauge tap, by switch warning indicator spare is installed and is constituted.This warning indicator spare can be selected electric detonator and short-circuit signal checkmark field for use, also can be at time delay gauge tap back tipping short-circuit signal radio transmitter.The short trouble alarm principle is as follows: when high voltage transmission line power current during to the pylon short circuit, annular core isolates out the interference of high frequency thunder and lightning signal, the induced field that is produced makes around thereon coil and has produced induction current, the time delay gauge tap is opened, connected warning indicator spare, the indication alerting signal.
Advantage of the present utility model is: apparatus structure is simple, cost of manufacture is low, easy for installation, report to the police accurately, be convenient to search abort situation, high voltage transmission line is installed this alarm, need not pursue the root inspection step by step when being short-circuited, can be directly according to the AIS sign, the sending box alerting signal that receives as signal flag or radio receiver, repair, save time, laborsaving, economical.
The utility model has following accompanying drawing: Fig. 1 to be mark among the utility model warning circuit structure principle chart figure for the utility model view Fig. 2 directly perceived that reports to the police: 1 is pylon; 2 is high voltage transmission line, and 3 is insulator, and 4 is the utility model alarm, and 5 is the metal connecting line between pylon and high voltage transmission line insulator.
Embodiment: iron-core coil: power 5-80W, overvoltage protection pressure sensitive voltage 56V.Signal limiter: stabilivolt 6-12V, bypass condenser 50V220 μ F.Time delay gauge tap: adopt the 6-12V DC relay.Warning indicator spare: the short circuit checkmark field in electric detonator and the warning box.When hi-line was short-circuited, induction power frequency direct current was ignited the electric detonator in the newspaper pipe box, dished out and hung over box and indicate the short trouble position outward being enclosed in the interior signal flag of box body.
