Description
Technical field:
The utility model relates to electrical equipment technical field, is specifically related to a kind of mechanical interlocks of high-tension switch cabinet.
Background technology:
High-tension switch cabinet refers to for electric power system generating, transmission of electricity, distribution, electric energy conversion and has consumed the device of the effects such as break-make, control or protection; electric pressure is between 3.6KV-550KV; mainly comprise circuit breaker, high voltage isolator and earthed switch, high voltage load switch, high pressure automatic reclosing and sectionalizer, several large classes such as high-voltage actuating mechanism, high-voltage explosion-proof power distribution equipment and high-tension switch cabinet.Domestic traditional central-positioned high-voltage switch cabinet adopts at present " five is anti-" is all that after high-voltage board, shrouding is integrated form, the earthed switch mechanical interlocking that directly shrouding does therewith.The drawback of the method is because rear shrouding is integral type, and on-site maintenance needs to operate together with multiple staff in the time of maintenance, wastes time and energy.If earthed switch interlocking goes wrong, staff understands mistakenly entering charged chamber, causes on-the-spot electric power system to go wrong, and is mainly that great personal safety accident occurs.
Utility model content:
The purpose of this utility model is to provide a kind of mechanical interlocks of high-tension switch cabinet, and the workload that it can reduce a staff is time saving and energy saving, and realizes the mistakenly entering charged chamber in " five is anti-", prevents human casualty accident.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises rear upper sealing plate, rear lower shrouding, rear middle cross beam, the bent plate of interlocking up and down, up and down locking bar, torsion spring, up and down lock handle, spacer pin, rear lower shrouding is connected with earthed switch by interlock, the side of bent plate of interlocking is up and down arranged in rear upper sealing plate by bolt, interlock bent plate up and down by matching with up and down locking bar on the gap on it, up and down locking bar upper surface is semicircular structure, and up and down locking bar is located in rear middle cross beam, the middle and upper part of up and down locking bar is arranged with torsion spring, the bottom of up and down locking bar is connected with up and down lock handle by circular hole, spacer pin is arranged on the bottom of rear middle cross beam.
Operation principle of the present utility model: the rear upper and lower shrouding of switch cubicle need to be sealed when power transmission, after first installing, upper sealing plate is installed rear lower shrouding again, when after after upper sealing plate installs, be arranged on the gap of the bent plate of interlocking up and down in this shrouding, just in time clamp up and down locking bar (now the semicircle upper surface of up and down locking bar is consistent with the gap direction of up and down bent plate), the up and down lock handle being connected with up and down locking bar stretches out outside cabinet and becomes 90 degree angles with rear middle cross beam; Descend afterwards in the process of shrouding in installation, can drive up and down lock handle to rotate, until it is forwarded in cabinet, when after after lower shrouding installs, the semicircle upper surface of up and down locking bar becomes 90 degree angles with the gap direction of the bent plate of interlocking up and down, and bent plate is pinned, and prevents the charged rear upper sealing plate of opening, so just realize the mistakenly entering charged chamber in " five is anti-", prevented human casualty accident.
In the time of maintenance, upper and lower cover plate after switch cubicle need to be taken off, (this descends shrouding and earthed switch interlocking device after one's death first to take off rear lower shrouding, now earthed switch is in closing position, rear lower shrouding can be opened), the position that up and down lock handle rotates to spacer pin under the effect of torsion spring stops, and up and down locking bar semicircle upper surface now just in time overlaps with the direction of the bent plate gap of interlocking up and down, rear upper sealing plate can be opened, and has met high pressure " five is anti-" requirement.
The utlity model has following beneficial effect: the workload that it can reduce a staff, time saving and energy saving, and realize the mistakenly entering charged chamber in " five is anti-", prevent human casualty accident.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises rear upper sealing plate 1, rear lower shrouding 2, rear middle cross beam 3, the bent plate 4 of interlocking up and down, up and down locking bar 5, torsion spring 6, up and down lock handle 7, spacer pin 8, rear lower shrouding 2 is connected with earthed switch by interlock, the side of bent plate 4 of interlocking is up and down arranged in rear upper sealing plate 1 by bolt, interlock bent plate 4 up and down by matching with up and down locking bar 5 on the gap on it, up and down locking bar 5 upper surfaces are semicircular structure, and up and down locking bar 5 is located in rear middle cross beam 3, the middle and upper part of up and down locking bar 5 is arranged with torsion spring 6, the bottom of up and down locking bar 5 is connected with up and down lock handle 7 by circular hole, spacer pin 8 is arranged on the bottom of rear middle cross beam 3.
The operation principle of this embodiment: the rear upper and lower shrouding of switch cubicle need to be sealed when power transmission, after first installing, upper sealing plate 1 is installed rear lower shrouding 2 again, when after after upper sealing plate 1 installs, be arranged on the gap of the bent plate 4 of interlocking up and down in this shrouding, just in time clamp up and down locking bar 5 (now the semicircle upper surface of up and down locking bar 5 is consistent with the gap direction of the bent plate 4 of interlocking up and down), the up and down lock handle 7 being connected with up and down locking bar 5 stretch out cabinet outer and with 3 one-tenth 90 degree angles of rear middle cross beam; Descend afterwards in the process of shrouding 2 in installation, can drive up and down lock handle 7 to rotate, until it is forwarded in cabinet, when after after lower shrouding 2 installs, the semicircle upper surface of up and down locking bar 5 becomes 90 degree angles with the gap direction of the bent plate 4 of interlocking up and down, and the bent plate 4 of interlocking up and down pins, and prevents the charged rear upper sealing plate of opening, so just realize the mistakenly entering charged chamber in " five is anti-", prevented human casualty accident.
In the time of maintenance, upper and lower cover plate after switch cubicle need to be taken off, (this descends shrouding and earthed switch interlocking device after one's death first to take off rear lower shrouding 2, now earthed switch is in closing position, rear lower shrouding 2 can be opened), the position that up and down lock handle 7 rotates to spacer pin 8 under the effect of torsion spring 6 stops, and the semicircle upper surface of up and down locking bar 5 now just in time overlaps with the direction of bent plate 4 gap of interlocking up and down, rear upper sealing plate 1 can be opened, and has met high pressure " five is anti-" requirement.
This embodiment has following beneficial effect: the workload that it can reduce a staff, and time saving and energy saving, and realize the mistakenly entering charged chamber in " five is anti-", prevent human casualty accident.
