The three sensors are positioned right below the high voltage living wire to be checked and are relatively in parallel with the high voltage living wire, the down lead of the three sensors are connected with the converting terminal of the display; a dash receiver and a polar plate are arranged in the nylon rod pipe of the three sensors, which are sustained in the middle of the pipe by the shoe block at the two ends; the display comprises a chassis, a power panel, a panel, a main board, a converting terminal block and a display panel. The utility model can check whether the high voltage equipment has electricity in a non-contact mode off the safe distance by use of the electric field checking sensor with great sensitivity, directivity and resistance to interference. Besides, the utility model has the functions of displaying by splitting phase and displaying three phases synchronously which can display the status of the live circuit directly and digitally.
Description
Technical field

Background technology
The at present domestic high voltage that is applied in detects, and still adopts electrostatic voltmeter and voltage transformer (VT), all require to contact with measured object, the insulating requirements height, operate careless slightly will be accidents caused.Another capacitance-voltage-distributing type high voltage display device is to adopt capacitor that high voltage is carried out dividing potential drop to extract signal, thereby judges whether measurand is charged, and this still belongs to contact type measurement, has the possibility of insulation breakdown too.From the high voltage display device of external import, though have contactlessly, but still be that phase-splitting shows and costs an arm and a leg, can't popularize.
Summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model is to be power department, and a kind of three-phase control induction type high-voltage electriferous display locking device especially is provided in the UHV (ultra-high voltage) field, adopts noncontact electrical verification mode.Test 50HZ, 10～500KV are indoor, the charged state of outdoor electrical equipment or network.Can phase-splitting show and the demonstration of three synchronised.
For realizing above purpose, the utility model is made up of three sensors 14 and display 1 two parts, three sensors 14 be positioned under the tested high voltage transmission line and with the high voltage transmission line opposing parallel, cable 10 is connected with the Converting terminal row 9 of display 1 under the drawing of three sensors 14; Described display 1 is made up of cabinet 7, power panel 2, panel 8, mainboard 15, Converting terminal row 9, display board 6, light emitting diode indication end 4, liquid crystal indication end 5, power panel 2, mainboard 15 place in the cabinet 7, the external 220 volts of power supplys of power panel 2 input ends, power panel 2 output termination mainboards 15, panel 8 places cabinet 7 outsides, and Converting terminal row 9 places the lower end of cabinet 7; Dash receiver 12 and pole plate 13 are set in the nylon rod body 11 of described three sensors 14, and dash receiver 12 and pole plate 13 are supported in the middle of the body by the two end supports piece.
The utility model can be outside the high voltage alive equipment safe distance, whether utilize the electric field detecting sensor to carry out the non-contact detection high-tension apparatus charged, and have higher sensitivity and a directivity, antijamming capability is strong, possesses the repertoire that phase-splitting shows, also can three synchronised show the directly digital alive circuit situation that shows.Charged when tested high-tension apparatus, can glisten and audio alert is exported block signal simultaneously, cut off " five is anti-" loop automatically, the high pressure isolation knife can't be operated, realize forcing sealing.Can also provide node signal for the electrical verification of " micro_computer five_proof device ".
