Abstract
The utility model relates to a misoperation prevention mechanism for a ring network cabinet in the technical field of power distribution cabinets. The misoperation prevention mechanism for the ring network cabinet comprises a cabinet body, the front of the upper part of the cabinet body is provided with an operation panel, a cable room door is arranged below the operation panel, the operation panel is provided with an isolating switch operation hole, an isolating switch and a permanent magnet switch are arranged in the cabinet body, the operation panel is provided with a baffle plate, one end of the baffle plate is hinged on the operation panel, the lower side of the baffle plate is connected with a pull rope connected with a permanent magnet switch opening and closing mechanism, and the upper side of the baffle plate is connected with a reset spring pulling the baffle plate upwards. When the permanent magnet switch is closed or opened, the baffle plate just covers or exposes the isolating switch operation hole. When the permanent magnet switch is closed, the baffle plate covers the isolating switch operation hole so that the isolating switch is not operated by mistake; and when the permanent magnet switch is opened, the isolating switch operation hole is exposed so that the isolating switch can be operated. Therefore, the probability of accidents is reduced, and safety and reliability are improved. The device can be safely used in the ring network cabinet.
Description
Technical field
The utility model relates to a kind of power distribution cabinet, particularly a kind of safety guard of ring main unit.
Background technology
In ring main unit, isolating switch closes a floodgate vacuum switch behind combined floodgate, and major loop is connected; When needs cut-out work, need earlier the vacuum switch separating brake is disconnected isolating switch again, can not bringing onto load positive opening isolating switch, otherwise may burn parts such as contact knife, contact because of electric current greatly, cause the accident.In the prior art, isolating switch is to operate by the isolator operation hole that the guidance panel rear arranges, and inserts isolator operation hole operation isolating switch by handle.Its weak point is: easily misoperation, not during separating brake, operating personnel just can insert handle in the isolator operation hole, cause misoperation easily at vacuum switch.In addition, cable vault's door is arranged on the guidance panel below, when ring main unit moves, does not allow cable vault's door is opened, although operational procedure has such restriction, the situation that nothing operation, nothing are opened cable vault's door also happens occasionally.At present, there is no the good technical means and take precautions against this class misoperation.
The utility model content
The purpose of this utility model provides a kind of ring main unit anti-misoperation mechanism, can take precautions against misoperation technically, reduces risk.
The purpose of this utility model is achieved in that a kind of ring main unit anti-misoperation mechanism, comprise cabinet, the cabinet top front face is provided with guidance panel, the guidance panel below is provided with cable vault's door, guidance panel is provided with the isolator operation hole, isolating switch and permanent-magnetic switching are arranged in the cabinet, described guidance panel is provided with baffle plate, baffle plate one end is hinged on the guidance panel, the baffle plate downside is connected with the drag-line that is connected with the permanent-magnetic switching close/open machine, the baffle plate upside is connected with the upwards back-moving spring of tractive baffle plate, and when permanent-magnetic switching closes a floodgate or during separating brake, baffle plate covers just or exposes the isolator operation hole.
In this device, when permanent-magnetic switching closed a floodgate, the permanent-magnetic switching close/open machine spurred baffle plate through drag-line, made baffle plate masked isolation switching manipulation hole, and handle can not be inserted in the isolator operation hole, and therefore, this moment, isolating switch can be by misoperation; When the permanent-magnetic switching separating brake, drag-line is released, and back-moving spring pulling baffle plate rotates, and exposes the isolator operation hole, and at this moment, handle can insert in the isolator operation hole isolating switch is operated.Compared with prior art, the utility model can avoid isolating switch under the bringing onto load situation by separating brake by force, reduced the accident odds, improved fail safe and dependability.This device can be used safely on ring main unit.
Smooth and easy for the motion of assertive evidence baffle plate, spacing position up and down can be provided simultaneously, the described baffle plate other end is provided with arc guide groove, and guidance panel is provided with guide finger, and guide finger inserts in the gathering sill.Guide finger not only can lead to baffle plate, and simultaneously, but the extreme position of defining baffle motion guarantees that the baffle plate motion is normal.
For preventing that further cable vault's door is opened when ring main unit moves, described guidance panel is provided with the lifting latch, and when permanent-magnetic switching closes a floodgate, conflict at the baffle plate downside in lifting latch upper end, and insert on cable vault's door cable vault's door locked lifting latch lower end.After permanent-magnetic switching closed a floodgate, the lifting latch was blocked by baffle plate, can not move upward, and can avoid its artificial mistake to open.Only behind the permanent-magnetic switching separating brake, under action of reset spring, baffle plate rotates, and abdicates lifting latch superjacent air space, and the lifting latch can upwards be extracted, thereby cable vault's door can be opened.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fundamental diagram.
Wherein, 1 lifting latch, 2 gathering sills, 3 guide fingers, 4 isolator operation holes, 5 back-moving springs, 6 baffle plates, 7 hinged rotating shafts, 8 drag-lines, 9 guidance panels, 10 cable vault's doors.
Embodiment
As shown in the figure, be ring main unit anti-misoperation mechanism, comprise cabinet, the cabinet top front face is provided with guidance panel 9, guidance panel 9 belows are provided with cable vault's door 10, guidance panel 9 is provided with isolator operation hole 4, isolating switch and permanent-magnetic switching are arranged in the cabinet, handle is inserted in the isolator operation hole 4, but disconnecting switch operation is closed a floodgate and separating brake, guidance panel 9 is provided with baffle plate 6, baffle plate 6 one ends are hinged on the guidance panel 9 through hinged rotating shaft 7, baffle plate 6 can be rotated around hinged rotating shaft 7, and baffle plate 6 downsides are connected with the drag-line 8 that is connected with the permanent-magnetic switching close/open machine, and baffle plate 6 upsides are connected with the upwards back-moving spring 5 of tractive baffle plate 6, when permanent-magnetic switching closes a floodgate, drag-line 8 pulling baffle plates 6 lucky masked isolation switching manipulation holes 4, when the permanent-magnetic switching separating brake, back-moving spring 5 pulling baffle plates, 6 rotations are also exposed isolator operation hole 4.Baffle plate 6 other ends are provided with arc guide groove 2, and guidance panel 9 is provided with guide finger 3, and guide finger 3 inserts in the gathering sill 2.Also be provided with lifting latch 1 on the guidance panel 9, when permanent-magnetic switching closes a floodgate, conflict at baffle plate 6 downsides in lifting latch 1 upper end, and insert on cable vault's door 10 10 lockings of cable vault's door lifting latch 1 lower end.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection range of the present utility model.
