Abstract
The invention discloses a 10kV insulating rod for preventing ground fault, which is characterized by comprising a first insulating rod (1), a second insulating rod (2) and a third insulating rod (5), wherein the first insulating rod (1) is connected with the second insulating rod (2) through a first connector (3), the second insulating rod (2) is connected with the third insulating rod (5) through a second connector (4), the second connector (4) is connected with an audible and visual alarm (7), the third insulating rod (5) is connected with a sensor (6) provided with a metal pulley, the sensor (6) is connected with the audible and visual alarm (7) through a lead wire, the first insulating rod (1) and the second insulating rod (2) are arranged in the horizontal direction, and the third insulating rod (5) is inclined downwards. The 10kV insulating rod is simple and practical in structure, is portable, is safe and reliable, and can find out ground faults of a 10kV power distribution network effectively and quickly, and guarantees personal safety.
Description
Technical field:
The present invention relates to a kind of insulation rod of 10kV preventing ground fault, 10kV distribution work on the spot can be widely used in, especially particularly outstanding to effect during generation earth fault, belong to electricity supply and use technology field.
Background technology:
In 10kV distribution working site, once generation line-to-ground fault, staff according to safety requirements must ensure from least indoor 4 meters of earth point distance, outdoor 8 meters, but at the scene in the course of work sometimes because trouble spot is failed to understand, the electric shock because safe distance deficiency causes may be there is.Therefore, be badly in need of the insulation rod of a kind of 10kV preventing ground fault of invention, at the scene of looking up the fault, this insulation rod can, sending sound and light alarm close to during trouble spot, remind staff away from trouble spot, general location trouble spot while guaranteeing personal safety.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple and practical, being easy to carry, safe and reliable, effective fast finding 10kV distribution earth fault, the insulation rod of the 10kV preventing ground fault guaranteed personal safety.
Object of the present invention can be reached by following measure: a kind of insulation rod of 10kV preventing ground fault, it is characterized in that it comprises the first insulation rod, the second insulation rod, the 3rd insulation rod, first insulation rod connects the second insulation rod by the first web member, second insulation rod connects the 3rd insulation rod by the second web member, second web member connects audible-visual annunciator, the inductor of the 3rd insulation rod connecting band metallic sheave, inductor is connected by wire with audible-visual annunciator, in horizontal direction, the 3rd insulation rod is downward-sloping for first insulation rod and the second insulation rod.
In order to realize object of the present invention further, the angle between the second described insulation rod and the 3rd insulation rod is 135 °, and the total length of the first insulation rod and the second insulation rod is greater than 4 meters.
The present invention can produce following good effect compared with the prior art:
1. the dismounting of insulation rod sectional, is easy to carry.
2. when night works, whether have hole hole, avoid tumble injury if staff both can have been helped to detect front, can get an electric shock by the on-the-spot person occurred of preventing ground fault again.
3. sound, light two kinds warning, enhance reliability, guarantee to play the effect of warning.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of insulation rod (see Fig. 1) of 10kV preventing ground fault, it comprises the first insulation rod 1, second insulation rod 2, 3rd insulation rod 5, first insulation rod 1 connects the second insulation rod 2 by the first web member 3, second insulation rod 2 connects the 3rd insulation rod 5 by the second web member 4, second web member 4 connects audible-visual annunciator 7, the inductor 6 of the 3rd insulation rod 5 connecting band metallic sheave, inductor 6 is connected by wire with audible-visual annunciator 7, first insulation rod 1 and the second insulation rod 2 are in horizontal direction, 3rd insulation rod 5 is downward-sloping, angle between second insulation rod 2 and the 3rd insulation rod 5 is 135 °, the total length of the first insulation rod 1 and the second insulation rod 2 is greater than 4 meters, namely the horizontal length of this insulation rod is greater than 4 meters.When staff uses this insulation rod in the work on the spot having earth fault, when inductor 6 sense reach that ground voltage is higher than 10V around time, acoustic-optic alarm 2 can be triggered, make it send sharp-pointed whistle and red flare, remind staff close to trouble spot.
