Capacitor discharge instrument
Technical field
The present invention relates to a kind of capacitor discharge instrument, belong to capacitor discharge technical field.
Background technology
Capacitor bank power failure work, although there is electric discharge PT and earthing switch blade to discharge most of electric charge, at that time electric capacity
Residual charge is still had on device, especially after capacitor faults fuse disruption, electric charge can be remained largely on the capacitor, such as
Without electric discharge, it will get an electric shock;Power safety is provided, into before capacitor bank work, it is necessary to which capacitor is multiple one by one
Electric discharge.
Working site is without special electric discharge instrument so far at present, and the general ground wire for borrowing electric substation is discharged, and needs to carry out
The extra ground wire of row borrows also formality;Electric substation's inner capacitor group typically can all arrange 2 to 3 layers(It is existing to see Fig. 1 and Fig. 2
The schematic diagram of frame type capacitive device group), discharge operation personnel should reduce the number of times for operation of ascending a height as far as possible;It is homemade in early days to put
Electric tool, such as Fig. 3 are the structural representations of discharging rod of capacitor of the prior art, including insulating bar 11, point discharge body 12,
It is that insulation nose installs point discharge body composition additional, can only carries out a little discharging.For capacitor, except needing single-stage pair
Ground discharges, and also to carry out the alternate electric discharge of two-stage(As shown in Figure 4 be existing single capacitor structural representation), put in early days
Electric tool cannot meet electric discharge and require.
The content of the invention
The class of electric discharge instrument one of current onsite application is traditional ground wire, and another kind of is that homemade insulating bar leading portion places electricity
Tip portion.Can be for directly discharging capacitor single-stage, but 2 grades of alternate electric discharges can not be carried out to capacitor, such as
This leaves hidden danger.If carrying out discharge operation using 2 piece-root grafting ground wires or 2 discharging rods, can be accomplished simultaneously to capacitor
Over the ground and the need for alternate electric discharge, it is contemplated that frame type capacitive device group, typically all set more than 2 to 3 layers, with respect to ground level compared with
Height, discharge operation personnel will certainly will be ascended a height operation repeatedly, and the position that stand different is operated, and fewer work is carried on hand
Tool work more can guarantee that safety and conveniently.
Single-stage discharging function and usage exactly according to such situation, are carried out upgrading improvement by the present invention, by being grasped in insulation
Make design between rod and discharge metal rod and install Flexible Connector additional, reach the effect for changing operation direction, produce operating personnel
Stand can easily carry out at an arbitrary position and meanwhile over the ground with alternate discharge operation, it is ensured that discharge operation is safe and reliable, laborsaving convenience
Progress.
Prior art has the disadvantage that:For frame type capacitive device group, 2 are typically all set, more than 3 layers, before work
Multiple discharge one by one is needed, operating personnel must just ascend a height to discharge range repeatedly, then operating personnel are impossible at any time
