Abstract
The utility model discloses a kind of circuit breaker chassis interlock of switch cubicle, median septum in cabinet offers a strip shape gob along slide rail length direction, the connecting plate that strip shape gob side is fixedly connected with a L shape is positioned at below median septum, described connecting plate is hinged with a baffle plate, the upper end of baffle plate reaches above median septum, the bottom of baffle plate is connected with a push rod, one end of push rod extend out to lower turnover panel front, is connected with an extension spring between position baffle plate top and median septum differing from push rod side; When the cabinet door of switch cubicle opens wide, described baffle plate is in vertical state under the pulling of extension spring, stops that circuit breaker chassis moves to service position; After the closedown of cabinet door puts in place, cabinet door compressing push rod drives baffle plate to rotate, and baffle plate does not produce stop to circuit breaker chassis, and circuit breaker just can be moved into service position.This interlock structure is simple, and parts are few, ensure that the use safety of switch cubicle.
Description
Technical field
The utility model belongs to high-tension switch cabinet apparatus field, is specifically related to the interlock between the circuit breaker chassis of switch cubicle and door of switch cabinet.
Background technology
Mechanical chain is not had between current KYN28A-12 type circuit breaker and the front Xiamen of switch cubicle, easily cause just circuit breaker being shaken into service position under front Xiamen does not have closed condition, by breaker closing, loop is charged, do not meet the requirement preventing mistakenly entering charged chamber in five anti-interlockings, loop is easily caused to have a power failure, the major accidents such as personal safety.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of structure simple, easy for installation, the circuit breaker chassis interlock of the pass cabinet of use safety.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of circuit breaker chassis interlock of switch cubicle, include cabinet, cabinet front is hinged with cabinet door, be installed with the median septum of a level in the middle part of cabinet, median septum front portion is bent to form a vertical lower turnover panel downwards, in described cabinet, two side walls is positioned at above median septum and is installed with two slide rails, slide rail slidably connects the circuit breaker chassis installing circuit breaker, it is characterized in that: described median septum offers a strip shape gob along slide rail length direction, the connecting plate that strip shape gob side is fixedly connected with a L shape is positioned at below median septum, described connecting plate is hinged with a baffle plate, the upper end of baffle plate reaches above median septum, the bottom of baffle plate is connected with a push rod, one end of push rod extend out to lower turnover panel front, an extension spring is connected with between position baffle plate top and median septum differing from push rod side, described baffle plate both sides are connected with two wing plates, and the wing plate near lower turnover panel is front wing panel, and front wing panel is equal with baffle length, and the wing plate away from lower turnover panel is rear fender, and rear fender is connected to baffle plate upper position, one end of described extension spring is connected on rear fender, described push rod is through described front wing panel bottom and push rod is positioned at front wing panel front and back position is connected with nut, the hole that described rear fender passes for push rod is bar hole, described baffle plate upper surface is inclined-plane, drives push rod to drive flapper and baffle plate upper surface is concordant with median septum when cabinet door is closed.
Preferably: the end winding support that described push rod is positioned at lower turnover panel front is connected with the top of a quality of rubber materials.
Compared with prior art, the beneficial effects of the utility model are: when the cabinet door of switch cubicle opens wide, and described baffle plate is in vertical state under the pulling of extension spring, and the upper end of baffle plate stops that circuit breaker chassis moves to service position; Only have after the closedown of cabinet door puts in place, cabinet door compressing push rod drives baffle plate to rotate, and when making the upper surface of baffle plate turn to concordant with median septum, baffle plate does not produce stop to circuit breaker chassis, and circuit breaker just can be moved into service position.This interlock structure is simple, and parts are few, easy to assembly, ensure that the use safety of switch cubicle, ensured the personal safety of operating personnel.

Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 5, the circuit breaker chassis interlock of a kind of switch cubicle described in the present embodiment, includes cabinet 1, and cabinet front is hinged with cabinet door 2, be installed with the median septum 4 of a level in the middle part of cabinet, median septum front portion is bent to form a vertical lower turnover panel 41 downwards, in described cabinet, two side walls is positioned at above median septum and is installed with two slide rails 5, slide rail slidably connects the circuit breaker chassis 6 installing circuit breaker, described median septum offers a strip shape gob 42 along slide rail length direction, the connecting plate 8 that strip shape gob side is fixedly connected with a L shape is positioned at below median septum, described connecting plate is hinged with a baffle plate 7, the upper end of baffle plate reaches above median septum, the bottom of baffle plate is connected with a push rod 3, one end of push rod extend out to lower turnover panel front, an extension spring 9 is connected with between position baffle plate top and median septum differing from push rod side, described baffle plate both sides are connected with two wing plates, and the wing plate near lower turnover panel is front wing panel 71, and front wing panel is equal with baffle length, and the wing plate away from lower turnover panel is rear fender 72, and rear fender is connected to baffle plate upper position, one end of described extension spring is connected on rear fender, described push rod is through described front wing panel bottom and push rod is positioned at front wing panel front and back position is connected with nut, and two are left gap between nut and front wing panel, both promotes baffle plate by push rod, is beneficial to flapper again, the hole that described rear fender passes for push rod is bar hole, described baffle plate upper surface is inclined-plane, drives push rod to drive flapper and baffle plate upper surface is concordant with median septum when cabinet door is closed.The end winding support that described push rod is positioned at lower turnover panel front is connected with the top 31 of a quality of rubber materials.
When the cabinet door of switch cubicle opens wide, described baffle plate is in vertical state under the pulling of extension spring, offsets on rear side of the top of now baffle plate with bar hole.The upper end of baffle plate stops that circuit breaker chassis moves to service position; Only have after the closedown of cabinet door puts in place, cabinet door compressing push rod drives baffle plate to rotate, and when making the upper surface of baffle plate turn to concordant with median septum, baffle plate does not produce stop to circuit breaker chassis, and circuit breaker just can be moved into service position.This interlock structure is simple, and parts are few, easy to assembly, ensure that the use safety of switch cubicle, ensured the personal safety of operating personnel.
