Abstract
The invention discloses a low-voltage electrical testing device. The low-voltage electrical testing device consists of a probe, a current-limiting resistor, a charging state display and a testing handle, and is characterized in that a multi-section insulating rod which can be assembled and disassembled is arranged at the front end of the electrical testing device; the two ends of each section of the insulating rod are respectively provided with a copper stud and a copper nut; the nut is embedded into the end surface of the insulating rod; the stud and the nut of every two sections of the insulating rod can be screwed together; the stud and the nut at the two ends of each section of the insulating rod are connected together through a conducting wire in the insulating rod; the stud and the nut at the two ends of the insulating rod at the most front end are connected with each other through the limiting-current resistor in the insulating rod; the probe is screwed on the insulating rod at the most front end in a threaded connection way; the charging state display is connected with the last section of the insulating rod; and the tail end of the charging state display is connected with the testing handle. By the low-voltage electrical testing device, operating personnel can test whether electrical equipment on an electric pole platform is charged or not without climbing on the electric pole platform, so that human physical strength is saved; the work efficiency and the safety are improved; and the personnel safety accidents are avoided.
Description
Technical field
The present invention relates to a kind of electroscopic device of electrical equipment of low voltage.
Background technology
At present, because existing low pressure electroscope (380V) all is the instrument of miniaturization, its galvanoscopic probe length is inadequate, and all needs again the in-plant galvanoscopic pilot lamp light on and off state of watching.So the distribution repairman of electric industry system when whether the chopper switch of the step down side on check electric pole platform has electricity, need to climb on the electric pole platform, carries out electrical verification near transformer equipment.This operational method not only expends people's physical efficiency, and operating efficiency is low, and has certain danger, very easily causes the personal safety accident.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, be easy to carry about with one, detecting head can lengthen and with the low pressure electroscopic device of audio alarming signal.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of low pressure electroscopic device, the electroscopic device that is formed by probe, current-limiting resistance, power status display, test handle, it is characterized in that: the front end of this electroscopic device have one can assembly and disassembly the more piece insulating bar, two of every joint insulating bar is respectively with copper double-screw bolt and nut, and nut is embedded in insulating bar end face the inside, and the double-screw bolt of per two joint insulating bars and nut can be twisted and be connected together; The double-screw bolt at every joint insulating bar two ends and nut are all linked together by a wire of inside, the double-screw bolt at insulating bar two ends foremost and nut are that a current-limiting resistance by inside links together, probe is screwed on foremost the insulating bar in the mode that is threaded, power status display is connected on the final section insulating bar, and the end of power status display is connected on the test handle.
Described power status display can be the induction type audio signal alarm, also can be neon tube aura generator.
Described insulating bar should be able to bear the dielectric voltage withstand grade of 10KV.
Compared with prior art, advantage of the present invention is: this electroscopic device can make the operating personnel need not climb on the electric pole platform, can check the electrical equipment on the electric pole platform whether electricity is arranged, thereby save people's muscle power, improve operating efficiency and security, stopped the generation of personal safety accident.
Description of drawings
Fig. 1 is the structural representation of low pressure electroscopic device.
Among the figure: the 1-probe, the 2-current-limiting resistance, the 3-insulating bar, 4 power status displays, 5-tests handle.
Embodiment
Referring to Fig. 1.Low pressure electroscopic device of the present invention is comprised of probe 1, current-limiting resistance 2, power status display 4, test handle 5.Different from general electroscopic device is, the front end of this electroscopic device have one can assembly and disassembly more piece insulating bar 3, two of every joint insulating bar is respectively with copper double-screw bolt and nut, and nut is embedded in insulating bar end face the inside, and the double-screw bolt of per two joint insulating bars and nut can be twisted and be connected together; The double-screw bolt at every joint insulating bar two ends and nut are all linked together by a wire of inside, and the double-screw bolt at insulating bar two ends foremost and nut are that a current-limiting resistance 2 by inside links together; Probe 1 is screwed on foremost the insulating bar in the mode that is threaded, and power status display 4 is connected on the final section insulating bar, and the end of power status display 4 is connected on the test handle 5 of metal material.Power status display 4 can be the induction type audio signal alarm, also can be neon tube aura generator.Perhaps, both install on the electroscopic device simultaneously.Insulating bar 3 should be able to bear the dielectric voltage withstand grade of 10KV.
During use, test first the duty of power status display 4, if any alerting signal output, then electroscopic device is working properly, and such as the output of alarm free signal, then there is fault in electroscopic device, can not continue to use.Then, operating personnel can adjust the length of insulating bar 3 according to the actual conditions at scene, are advisable can make probe 1 test point that touches equipment under test.Operating personnel one hold insulating bar 3, and hold test handle 5, just can measure.Have audio alarming signal output or neon tube luminous, illustrate that equipment under test has electricity, the output of absence of audio alerting signal or neon tube are not luminous, illustrate that equipment under test does not have electricity.So far, test job finishes.
