Abstract
The present invention relates to a circuit detection device, in particular to a portable electroscope, which comprises a contact electroscope. The portable electroscope is characterized in that the contact electroscope is connected with an insulating rope, the other end of the insulating rope is fixedly wound on a rolling wheel, and the rolling wheel is connected with a retractable device capable of driving the rolling wheel to rotate forwards or backwards. Since the insulating rope is used instead of an insulating rod in the technical scheme, the present invention has the following advantages that: 1, the weight in the detection process is greatly reduced; 2, no installation of pulleys or cooperation of ground staff is needed, and thus the detection time is shortened and the number of the detection personnel is reduced; and 3, since the existing power transmission line adopts an aluminum stranded wire with a steel wire in the middle, and the power detection head of the electroscope is provided with a high-performance magnet, the contact electroscope can be accurately contacted with the power transmission line to be connected with the power transmission line for measurement. Therefore, the device is easy to carry and measure, effectively improves the measurement efficiency, reduces the required personnel, and enhances the detection safety.
Description
Technical field
The present invention relates to the electric circuit inspection device, particularly portable electroscope.
Background technology
According to " State Grid Corporation of China's electric power safety working regulation (circuit pack) " 3.3.1 bar before dead line job site attaching ground wire, should first electrical verification, identify the true no-voltage of circuit.During electrical verification, should use relevant voltage grade, qualified contact electroscope.Common used electroscope all adopts drawing and pulling type on the ultra-high-tension power transmission line at present, promptly according to the test voltage grade, corresponding contact electroscope is installed in telescopic insulating bar head, measures.During measurement, survey crew is gone up to the cross-arm of tower masthead portion earlier, and pulley is fixedly mounted on the cross-arm, by the insulation rope electroscope and insulating bar is transported to cat head by the ground staff, measures.The structure length of 330kV and above electric pressure has reached 4.5-8 meters at present, and the length of insulating bar will reach 5-9 meters like this, bring following problem to measurement: 1, carry inconvenience.When measuring, need carry utensils such as pulley, insulating bar, insulation rope; 2, the preliminary work before the test is loaded down with trivial details, labour intensity is big, the time is long.The personnel that last tower bar is measured need carry pulley, insulation rope etc., need pulley is installed behind cat head, putting down the insulation rope, cooperate personnel that insulating bar is transported to cat head by ground, just can measure, time-consuming, effort; 3, the measurement difficulty is big, security is low.Because scalable insulating bar is very long, the amplitude of oscillation is bigger during measurement, influences the electrical verification effect on the one hand, brings potential safety hazard on the other hand.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of and carry, measure portable easily electroscope.
For achieving the above object, technical scheme of the present invention is: a kind of portable electroscope, comprise the contact electroscope, and it is characterized in that the contact electroscope links to each other with the insulation rope, the other end of insulation rope is fixed and is wrapped on the rolling wheel, and rolling wheel links to each other with the draw off gear that can drive its rotating.
Above-mentioned contact electroscope is the contact electroscope of band boom unit.
Above-mentioned draw off gear is made up of battery, motor and gauge tap, and battery is electrically connected with motor by gauge tap.
Above-mentioned draw off gear is made up of battery, motor and gauge tap, and battery links to each other with rolling wheel by reduction gear with the output shaft that motor is electrically connected motor by gauge tap.
The switch that above-mentioned gauge tap is just being changeed by the may command motor is formed with the switch of control motor counter-rotating or is the combined switch that can realize above-mentioned functions.
Above-mentioned rolling wheel, battery, motor are fixedly mounted in the box body, and gauge tap is installed in box surface, have the mouth that is used to insulate and restricts and stretch out on box body.
Above-mentioned box body is to be made by insulating material.
The galvanoscopic electrical verification head of contact is equipped with magnet.
Technical scheme of the present invention has replaced insulating bar by the insulation rope, on the one hand the weight of test process is alleviated greatly, this point is extremely important for work high above the ground, need not to carry out the installation of pulley and ground staff's cooperation on the other hand, shortens and reduced detection time and personnel; Three, because existing power transmission line is the aluminum stranded conductor that has steel wire in the middle of adopting, the contact electroscope is being put down in the process of measuring, because galvanoscopic electrical verification head is equipped with high-performance magnet, just can easily electroscope be touched power transmission line accurately and connect, and finishes surveying work.In sum, this device has and carries, measures conveniently, improved effectively surveying work efficient, reduced the cooperation personnel, improved the safety when detecting.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is a circuit control synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, contact electroscope 3 links to each other with insulation rope 2, and the other end of insulation rope is fixed and is wrapped on the rolling wheel 1, and rolling wheel links to each other with the output shaft of motor 4, and battery 5 is electrically connected with motor by gauge tap 6.For the ease of carrying, rolling wheel, battery, motor can be fixedly mounted in the box body, have the mouth that the rope that is used to insulate stretches out on the box body, observation during simultaneously for the ease of measurement can accurately contact with tested power transmission line with the contact electroscope, the contact electroscope adopts the contact electroscope of band boom unit, and the galvanoscopic electrical verification head of contact is equipped with magnet.
During electrical verification; survey crew carries this electroscopic device and directly goes up cat head; after carrying out safety precautions; press the control gauge tap 6 that is installed in box surface; the rotation of driven by motor rolling wheel is moved down on the power transmission line that needs to detect the contact electroscope of the band boom unit that is installed in insulation rope lower end.Because measuring distance is bigger, though the contact electroscope has constant weight, the contact electroscope accurately to be placed on the power transmission line and acquire a certain degree of difficulty, for this reason, at the galvanoscopic electrical verification head of above-mentioned contact magnet is installed, when the contact electroscope is put into power transmission line magnetic force in one's power during scope, the galvanoscopic electrical verification head of contact just can be attracted on the power transmission line, finishes testing.When reclaiming the contact electroscope, by the insulation rope contact electroscope and power transmission line are broken away from earlier,, make the motor reverse rotation, just can realize the galvanoscopic recovery of contact by pressing the reverse rotation gauge tap.According to the requirement that electric power detects, this galvanoscopic box body is to be made by insulating material.In the gauge tap that box surface is installed two switches of control motor forward and reverse can be installed, a combined switch with control motor forward and backward also can be installed.
Being connected between motor 4 and the rolling wheel 1 can be installed reduction gear of the prior art, as gear or speed reduction unit according to rotating speed of motor between motor and rolling wheel.
