Abstract
The utility model relates to the high voltage switch cabinet field and especially relates to a heavy current generator outlet breaker handcart secondary plug interlock mechanism. The heavy current generator outlet breaker handcart secondary plug interlock mechanism comprises a handcart secondary plug and a handcart rack, wherein the secondary plug is connected with a switch cabinet separation chamber top wall through one nylon fluctuation telescopic tube, the switch cabinet separation chamber top wall is equipped with a general L-shaped lock plate with a reset spring, a bending portion of the lock plate is hinged with the switch cabinet separation chamber top wall, height of a short arm of the lock plate corresponds to an upper sealing plate of the handcart rack, the integral lock plate is prepared by rigid insulating material or prepared by a steel plate which is wrapped by the insulating material, and the short arm of the lock plate is equipped with a roller prepared by the insulating material. When a handcart is at a test position, the interlock mechanism has no motion; when the handcart shakes from the test position to a work position, the handcart contacts the lock plate, so the lock plate is made to rotate along a hinge point in a clockwise direction, a long arm of the lock plate just presses against a moving plug of the secondary plug, the moving plug is locked to prevent error plugging of the secondary plug.
Description
Technical field
The utility model relates to the high-tension switch cabinet field, especially relates to a kind of big current generator outlet breaker handcart secondary plug interlocking device.
Background technology
" five is anti-" device of high-tension switch cabinet generally can be divided into machinery, electric and comprehensive three classes, and " five is anti-" comprising: prevent the on-load branch, close isolating switch (stab contact); Prevent that mistake from dividing, mistake is closed circuit breaker; Prevent from closing when earthed switch is in make position circuit breaker; Prevent at charged mistiming splice grafting ground switch; Prevent between mistakenly entering into charged, more than five contents that prevent electric misoperation, be called for short " five is anti-", be the important measures of guaranteeing equipment and personal safety, preventing misoperation.
Secondary plug interlocking device is exactly one of " five is anti-", its effect is: make handcart type breaker after closing a floodgate in the service position, the advance and retreat mechanism of car is lockable and can't withdraws from, have only after circuit breaker is in gate-dividing state and just can shake handcart, this is in order to prevent that circuit breaker cart webge contact on-load from separating (on-load draws isolation switch).Before the utility model proposes, it is opposite with normal circuit breaker that KYN28A-12Z/5000A-50KA allots the motor outlet breaker, and socket causes existing interlocking device to use on handcart.Do not have interlocking device locking, secondary plug is breakneck, in case loosening, then can tripping (the divide-shut brake order can't be carried out), during fault such as the tripping meeting cause overstep tripping, can cause large-area power-cuts.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of big current generator outlet breaker handcart secondary plug interlocking device, establish interlocking device to solve in the handcart chamber, to guarantee that circuit breaker cart secondary plug-in unit when the service position is locked, can't transfer to or loosening.
The technical scheme that the utility model technical solution problem adopts is: big current generator outlet breaker handcart secondary plug interlocking device, comprise handcart secondary plug and handcart vehicle frame, described secondary plug links to each other with switch cabinet handcart compartment roof by a nylon fluctuation telescoping tube, described switch cabinet handcart compartment roof is equipped with the jam plate that is roughly " L " shape of a band back-moving spring, the bend of this jam plate and described switch cabinet handcart compartment roof are hinged, and the height of described jam plate galianconism is corresponding with the upper sealing plate of described handcart vehicle frame.In moving ahead process, touches handcart vehicle frame upper sealing plate the galianconism of jam plate, jam plate is rotated along the pin joint clockwise direction, described jam plate long-armed has suitable length, when the handcart vehicle frame arrives the service position fully, this is long-armed just in time to withstand described secondary plug, make it locked, can not be pulled out or loosening skidding off, guarantee handcart circuit breaker control circuit UNICOM when the service position.
As the further improvement of such scheme, the whole rigid insulation material that adopts of described jam plate is made, or adopts the steel plate that is coated in the insulating material to make.
As the further improvement of such scheme, the roller that a usefulness insulating material is made is equipped with at described jam plate galianconism place.
As the further improvement of such scheme, described jam plate bend has axis hole, and a bearing pin is housed in this axis hole, and these bearing pin two ends are fixed on the hanger on the described switch cabinet handcart compartment roof.
Beneficial effect: when handcart during in test position, this interlocking device is failure to actuate, and secondary plug can arbitrarily be transferred to, insert, and can overhaul circuit as requested, Quadratic Finite Element device and unaffected.When handcart shakes toward the service position from test position, can touch jam plate, it is rotated along the pin joint clockwise direction, the long-armed moving plug that just in time withstands described secondary plug of described jam plate, make it locked, prevent that secondary plug from being pulled out by mistake or become flexible minimizing accident potential.
Description of drawings
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is released state schematic diagram of the present utility model,
Fig. 2 is lock-out state schematic diagram of the present utility model.
Among the figure: 1. jam plate; 2. nylon fluctuation telescoping tube; 3. secondary plug; 4. handcart vehicle frame; 5. roller; 6. the upper sealing plate of handcart vehicle frame; 7. handcart compartment roof hanger.
Embodiment
Referring to Fig. 1, big current generator outlet breaker handcart secondary plug interlocking device, comprise handcart secondary plug 3 and handcart vehicle frame 4, secondary is inserted 3 and is linked to each other with switch cabinet handcart compartment roof by a nylon fluctuation telescoping tube 2, switch cabinet handcart compartment roof is equipped with the jam plate 1 that is roughly " L " shape of a band back-moving spring, the bend of jam plate 1 and switch cabinet handcart compartment roof are hinged, present embodiment adopts and leaves an axis hole at jam plate 1 bend, one bearing pin is housed in the axis hole, and the bearing pin two ends are fixed on the hanger 7 on the switch cabinet handcart compartment roof.
The height of jam plate 1 galianconism is corresponding with the upper sealing plate 6 of handcart vehicle frame.In moving ahead process, touches handcart vehicle frame upper sealing plate 6 galianconism of jam plate 1, jam plate 1 is rotated along the pin joint clockwise direction, jam plate 1 long-armed has suitable length, when handcart vehicle frame 4 arrives the service position fully, the long-armed tool of jam plate 1 just in time withstands secondary plug, make it locked, can not be pulled out or loosening skidding off, guarantee handcart circuit breaker control circuit UNICOM when the service position.
The jam plate 1 whole rigid insulation material that adopts is made, and as the high strength ambroin, perhaps adopts the steel plate that is coated in the insulating material (rubber or ambroin) to make.
In order to prevent the upper sealing plate of jam plate 1 scraping handcart vehicle frame, jam plate 1 can better be rotated, the roller that a usefulness insulating material (rubber or ambroin) is made can be equipped with in jam plate 1 galianconism place, the roller central shaft is fixed on plate 1 galianconism, so just can utilize roller to rotate and alleviate the two impact strength, prevent device failure.
