Abstract
The utility model discloses a door operation and interlocking device are forced to close by cubical switchboard, door operation and interlocking device are forced to close by cubical switchboard is including linking board, latch hook board, mounting panel, extension spring, hexagon head tapping screw, interlocking, apron, separation blade and unblock bent plate. The utility model discloses a superior effect lies in: door operation and interlocking device are forced to close by cubical switchboard's circuit breaker is only being closed and just can operated under the state of door plant. The operation of all mechanical deciliter and circuit breakers should be gone on under the condition that the cabinet door was closed. When the circuit breaker was in operating position, circuit breaker room door plant can not opened. Can open circuit breaker room door plant when only the circuit breaker is in test position.
Description
Technical field
The utility model relates to a kind of KYN28A-12 interlocking mechanism of switch cabinet, and particularly a kind of switch cubicle forces door-closing operation and interlocking device.
Background technology
At present, most of KYN28A-12 that market is sold forces door-closing operation, and namely breaker chamber door-plate can operating breaker when opening or closing.When conditioned disjunction misoperation because of exception causes internal short circuit fault to cause striking, great injury is caused to the person.
Utility model content
The utility model for solving the problems of the technologies described above, provide a kind of reasonable in design, structure simple, service-strong switch cubicle forces door-closing operation and interlocking device.
A kind of switch cubicle forces door-closing operation and interlocking device, described switch cubicle forces door-closing operation and interlocking device to comprise connecting plate, lock crook plate, supporting plate, extension spring, turret head tapping screw, interlocking, cover plate, catch and unblock bent plate, the middle part of described lock crook plate is provided with supporting plate, described connecting plate is positioned at one end of described lock crook plate, described extension spring is positioned at the right side of described lock crook plate, described connecting plate is arranged with described lock crook plate is mutually vertical, described turret head tapping screw is positioned on described lock crook plate, described interlocking is positioned at one end of described lock crook plate, described cover plate is positioned at the middle part of described interlocking, described catch is positioned at the top of described interlocking, described unblock bent plate is two both sides laying respectively at described interlocking.
Compared with prior art, switch cubicle of the present utility model forces the circuit breaker of door-closing operation and interlocking device only just can operate under the state of cutting out door-plate.All machinery deciliter and breaker operator should carry out when cabinet door is closed.When circuit breaker is in service position, breaker chamber door-plate can not be opened.Breaker chamber door-plate can be opened when only having circuit breaker to be in test position.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that switch cubicle of the present utility model forces door-closing operation and interlocking device first structural representation;
Fig. 2 is that switch cubicle of the present utility model forces door-closing operation and interlocking device second structural representation;
Fig. 3 is that switch cubicle of the present utility model forces door-closing operation and interlocking device the 3rd structural representation.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 3, a kind of switch cubicle forces door-closing operation and interlocking device to comprise connecting plate 1, lock crook plate 2, supporting plate 3, extension spring 4, turret head tapping screw 5, interlocking 6, cover plate 7, catch 8 and unblock bent plate 9, the middle part of described lock crook plate 2 is provided with supporting plate 3, described connecting plate 1 is positioned at one end of described lock crook plate 2, described extension spring 4 is positioned at the right side of described lock crook plate 2, described connecting plate 1 is arranged with described lock crook plate 2 is mutually vertical, described turret head tapping screw 5 is positioned on described lock crook plate 2, described interlocking 6 is positioned at one end of described lock crook plate 2, described cover plate 7 is positioned at the middle part of described interlocking 6, described catch 8 is positioned at the top of described interlocking 6, described unblock bent plate 9 is two both sides laying respectively at described interlocking 6.
When closing switch cabinet breaker room door-plate, in the process of circuit breaker cart from test position to service position, the connecting plate 1 of valve mechanism drives wins in succession, and lock for circuit breaker hook plate 2 is arranged on the turret head tapping screw 5 of breaker chamber door-plate.Like this, when circuit breaker is in service position, breaker chamber door-plate can not be opened.On the contrary, when circuit breaker returns to test position from service position, and earthed switch is in "on" position, and the turret head tapping screw 5 of breaker chamber door-plate is thrown off by 6 mechanisms that interlock, and breaker chamber door-plate can be opened.The turret head tapping screw 5 being installed on breaker chamber door-plate in addition, when interlocking 6 lost efficacy, in case of emergency can be removed from cabinet.
Switch cubicle of the present utility model forces the circuit breaker of door-closing operation and interlocking device only just can operate under the state of cutting out door-plate.All machinery deciliter and breaker operator should carry out when cabinet door is closed.When circuit breaker is in service position, breaker chamber door-plate can not be opened.Breaker chamber door-plate can be opened when only having circuit breaker to be in test position.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
