The conventional means that detects at present high-voltage transmission line insulator is with binoculars range estimation, i.e. the traditional detection mode of artificial work high above the ground.This mode not only labour intensity is large, and the operation surrounding enviroment are abominable, and live-working safety is low.In addition, because composite insulator has grading ring, sensor of the prior art may have the omission insulator umbrella in testing process, especially the one or two and last two insulating trips, and in case occur undetectedly, the staff can not in time find.
The utility model content
Technical problem to be solved in the utility model is that high rock electric line insulator of the prior art detects the manual detection mode of continuing to use, live-working safety is low, and the undetected situation of insulating trip easily occurs and then a kind of safe, high-voltage transmission line insulator live detector that detecting reliability is high is provided.
For solving the problems of the technologies described above, the utility model provides a kind of high-voltage transmission line insulator live detector, comprising:
Circular support is fastened and connected by two joint semi-circular bracket match-places, can be set in the insulator body periphery and does not contact with insulator;
At least one carriage of popping one's head in is fixedly installed on described circular support inwall by positioning screw;
Detection probe is packaged in described probe carriage inner, detects insulator electric field on every side by the square hole that is arranged on the described probe carriage;
Controller is fixed on the described probe carriage, the control end of the input termination detector of its internal circuit, and the input end of the described detection probe of output termination of its internal circuit is controlled described detection probe and is finished the detection action.
Described controller also comprises status indicator lamp, and described controller inside is provided with the circuit of the described status indicator lamp of control, and when described detection probe detected insulating trip, described status indicator lamp was bright.
Described controller also comprises hummer, and described controller inside is provided with the circuit of the described hummer of control, and when described detection probe detected insulating trip, described hummer was sounded a buzzer.
Be symmetrical arranged two probe carriages at described circular support inwall.
Described status indicator lamp adopts high strength variable L ED pilot lamp.
Technique scheme of the present utility model has following advantage:
(1) the high-voltage transmission line insulator live detector that provides of the utility model, comprise circular support, by being fixed in circular support for the probe carriage of package detection probe, circular support can be sheathed on exterior insulator, do not contact with insulator, can guarantee that thus detection probe can not touch insulator when insulator is detected, the security when operation is greatly improved.
(2) the high-voltage transmission line insulator live detector that provides of the utility model, controller also comprises status indicator lamp, by the circuit that is arranged at controller inside status indicator lamp is controlled, when detection probe detects insulating trip, the controllable state pilot lamp is bright, whether the prompting staff detects insulating trip, avoids undetected, can make thus the staff guarantee to detect insulating trips all on the insulator.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment of the utility model also by reference to the accompanying drawings, wherein:
Fig. 1 is the utility model high-voltage transmission line insulator live detector structural representation;
Wherein Reference numeral is: 1-circular support, the 2-carriage of popping one's head in, 3-detection probe, 4-controller, 5-status indicator lamp.
Embodiment
