Embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of main bus bar and feeder line branch electrical verification ground connection handcart, comprise base 17, it below the base 17 roller 11, above the base 17 support 18 and panel 14, fixing electrical verification contact arm 19, following electrical verification contact arm 20 and high pressure sensor 1 on the support 18, electrification display 13 is arranged on panel 14, ground connection interlocking device is set on support 18.Described ground connection interlocking gear comprises that one is fixed on operation disk 8 on the support, operation disk 8 outside fixing operation handles 3 by rotating shaft; A pilot hole 10 is set on the base 17, gear-stopping bar 12 is installed in the pilot hole 10, the upper end of gear-stopping bar 12 is by connector 9 and bearing pin and 8 inboard connections of operation disk; A ground connection cutter head 2 is fixed by bearing pin in the position of ground connection tool rest 6 correspondences on the support 18 of operation disk 8 upsides, fixes a pull bar 7 at operation disk 8 upsides by bearing pin, and the upper end of pull bar 7 is connected with ground connection cutter head 2 by bearing pin; The voltage extracting terminal of the high voltage variable light current on described electrification display 13 and the high pressure sensor 1 is electrically connected, and one pair of normally closed node is arranged in the electrification display 13, and the handle electromagnetic locking mechanism of setting on normally closed node and the panel is electrically connected.Described handle electromagnetic locking mechanism comprises lock hole 5, the location hole 21 on the operation disk and the electromagnetic lock 4 of lock handle on the handle.At base 17 location handgrip 16 and alignment pin 15 are set.
When being used for main bus bar electrical verification, ground connection, following electrical verification contact arm 20 unloads; When being used for the electrical verification of feeder line branch end, ground connection, last electrical verification contact arm 19 unloads.
Mechanical interlocking operation principle: when operating grip 3 pushes away from bottom to top, drive pull bar 7 by operation disk 8 and move upward, connect by ground connection cutter head 2 and ground connection tool rest 6.While disk operating mechanism 8 also drives gear-stopping bar 12 and moves downward by pilot hole 10, is inserted on the switch cubicle body ground connection interlocking hole.Thereby the handcart roller can't travel forward when making earthed switch close, effectively prevents charged mistake splice grafting ground switch.At this moment, earthed switch is in ground state, and electricity is arranged again in the switch cubicle, should be strictly on guard against in the electrical verification ground connection car push-on switch cabinet, causes the serious consequence of charged splice grafting ground switch.
The electrical interlock operation principle: the voltage extracting terminal of a high voltage variable light current is arranged on the high pressure sensor 1, go between to high-voltage charge display device 13, this electrification display is mounted on the handcart panel, height is pressed with, then electrification display is lighted, and is very directly perceived, 13 interior one pair of normally closed node in addition, go between to electromagnetic lock 4, when high pressure did not have electricity, this node was connected, and made the turn left limit withdrawal of electromagnetism lock core, lock hole 5 on the release lever, operating grip 3 allows operation.When height was pressed with electricity, this node became battle, and the electromagnetism lock core ejects to the right because of losing electromagnetic force, and the lock hole 5 that inserts on the handle makes its locking, and operating grip 3 can't rotate, thereby reaches the electrical interlock purpose.At this moment, after earthed switch is opened, but electrical verification in the handcart push-on switch cabinet when electricity, should be forbidden splice grafting ground switch.
