Description
Technical field
It ensures safety denotable discharging rod the utility model is related to one kind, belongs to high-voltage test application field.
Background technology
In the high-potting of power equipment, before changing wiring into trial zone, need to use discharging rod（Bar）, pair added
The equipment of high pressure is discharged, and so that the charge that test product accumulates is eliminated, to ensure the safety of testing crew.High-voltage discharging rod is
The indispensable managing security tools and instruments of high-pressure work personnel's operation.High-voltage discharging rod apply distribution transformer, power capacitor with
And in the maintenance of power cable, there is the equipment or component of storage charge function for these, after power failure, inspection operation
Before, it is necessary to adequately be discharged, it is ensured that personal safety.
Currently used discharging rod mainly contacts hook by metal, discharge resistance, insulating bar, connects connecing for discharge resistance
Ground flexible circuit conductor, wire clamp composition.This discharging rod the problem is that：
First, it cannot specify whether discharging rod is reliably connected with the earth.Before experiment, the discharge resistance of discharging rod should be by connecing
Ground flexible circuit conductor is reliably connected with ground potential.This is the vital link for ensureing testing crew safety.Due to proving ring sometimes
Border is complicated, and personnel accidentally touch when trying area's activity, so that discharging rod is connect with ground potential and be disconnected；Even testing crew
Carelessness forgets the connection for checking the ground wire other end and ground potential although earth lead is connect with grounding rod.At this point, connection
The ground wire of discharging rod with ground without reliably connection and it is good contact, then discharge operation performs practically no function, discharge operation is complete
After, actually there is no really electric discharges for high pressure test product, it would still be possible to dangerous high voltage.In this case people is tested
Member removes reconfiguration line again, personnel may be caused to get an electric shock.
Second, it cannot indicate whether to have discharged the charge on high voltage test product completely after electric discharge, i.e., cannot indicate
Whether it is also possible to causing the remaining voltage of Danger Electric shock risk.Standing order requires electric discharge 3 to set to could contact high electricity after five minutes
It is standby.Since discharging rod does not have specific voltage to indicate, when electric discharge, is likely to occur two kinds of situations, and one is electric discharges to have completed, but
Due to not indicating, continues equal a period of time by regulation and just think to complete electric discharge.Such case meeting growth test time, extend examination
Process is tested, test efficiency is reduced.Another situation is that electric discharge is not over, and is considered as having completed to discharge.Such case quilt
Certain residual charge is had on discharge equipment, Danger Electric shock risk is had when being in contact with it, and threatens the safety of operating personnel.
Utility model content

The ground wire is two, is connected on two wing nuts, is also serially connected between described two wing nuts
Loop detector；
It is provided with needle dc voltmeter between described two binding posts, it is in parallel with needle dc voltmeter between two binding posts
It is provided with discharge tube.
The insulating bar lower part is provided with handle and handguard ring.
The loop detector includes circuit indicator light, buzzer and switch button, inside there is button cell.
The size of the discharging rod is different and different according to test voltage grade.
The utility model has an advantageous effect in that compared with prior art：
（1）Discharging rod in this programme has two ground wires, even if there is one not have another of effective grounding in operation
It can play the role of ground connection.The probability very little that two ground wires are disconnected with the earth simultaneously.Using preceding progress earth-return circuit validity
Detection, can greatly improve experiment or the safety of service personnel.
（2）This programme is equipped with voltmeter and the dual instruction of electrostatic to the voltage of test product, and experiment service personnel can be allowed true
Determine, without subsequent operating procedure is carried out again in the case of high pressure, electric discharge adequately, to have ensured the safety of operating personnel.Two kinds of voltages refer to
Show that mode is intuitive, clear and passive, need not safeguard.Needle dc voltmeter will not be damaged by the protection of pipe that discharges because of overvoltage
It is bad.
The utility model has many advantages, such as simple in structure, easy to operate.

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
The denotable discharging rod as shown in Figure 1, one kind ensures safety, including insulating bar 8, ground wire 6 and metal hanger 1,
It is characterized in that：
8 top of the insulating bar is provided with metal hanger 1, and middle part is connected with two ground wires 6；
The insulating bar 8 is inverted L shape bar, including dielectric level bar 2 and insulation vertical bar 4,2 activity of the dielectric level bar
The metal foil 3 of two lightweights is set；There are two wing nut 7 and two binding posts 9 for 4 side wall of the insulation vertical bar setting；
The wing nut 7 is located at 9 lower section of binding post；
The ground wire 6 is two, is connected on two wing nuts 7, is also concatenated between described two wing nuts 7
There is loop detector 14；
Be provided with needle dc voltmeter 5 between described two binding posts 9, between two binding posts 9 with needle dc voltmeter 5
It has been arranged in parallel discharge tube 10.
The insulating bar lower part is provided with handle 16 and handguard ring 15.
The loop detector 14 includes circuit indicator light 11, buzzer 12 and switch button 13, inside there is button cell.
The utility model uses double earth wire structure, and loop detector 14 is added between two ground wires 6.Such as Fig. 2
Shown, loop detector 14 is constituted by 11,12,13, inside there is button cell, when switch 13 is opened, if 6 circuit of ground wire connects
It is logical, it indicates that lamp 11 is bright, and buzzer 12 makes a sound.If circuit is obstructed, it indicates that lamp 11 does not work, and buzzer 12 is not sent out
Whether intact sound can detect earth loop in this way.Double earth wire structure is also another after having a ground wire to be disconnected with ground simultaneously
Bar ground wire can play ground connection effect, greatly improve safety.
The utility model is using the double instruction structures of voltage.It is arranged on the horizon bar 2 at 1 end of discharging rod metal hanger two light
The metal foil 3 of matter, while a needle dc voltmeter 5 is accessed at binding post 9.When electric discharge, simultaneously due to needle dc voltmeter 5
It is associated on a part of resistance of discharge loop, the voltage swing after display partial pressure reflects the discharge scenario of high-pressure section indirectly.Together
When, discharge tube 10 is in parallel with needle dc voltmeter 5 by two binding posts 9, protects needle dc voltmeter 5 not because overvoltage is damaged
It is bad.When using static characteristic instructed voltage, metal hanger 1 is first used to contact the high-pressure section of test product, passes through the electric discharge electricity of vertical bar 4
Resistance electric discharge.Then metal foil 3 is used to contact test product high-pressure section again, if there is high pressure exists, two metal foils 3 are with electricity of the same race
Lotus can be separated by a distance because of repulsion, indicate with the presence of voltage.
The size of the discharging rod is different and different according to test voltage grade, it should it is designed according to test voltage grade,
The structure of this programme can be used in different voltage class.
