Abstract
The utility model discloses an opening and closing positioning device of grounding switch of middle-placed switch cabinet in electric power distribution system. The device is arranged a positioning bush(2) that has a 180 DEG boss and a positioning base(3) that has a 90 DEG boss on the main operation shaft of grounding switch. The positioning bush(2) is fastened on the main operation shaft(1) of grounding switch by the elastic dowel pin(4), while the positioning base(3) is fastened on the column(6) of switch cabinet by the bolt(5). The positioning bush(2) and the positioning base(3) cooperated to make rotation angle of the positioning bush(2) is 90 DEG. The opening and closing positioning device limits the rotation angle of opening and closing the switch into the range of 90 DEG required by the switch to effectively avoid wrong operation caused by the testing personnel who does not understand the operation procedure of the switch cabinet completely.
Description
Technical field
The utility model relates to a kind of power distribution earthed switch, and is especially relevant with a kind of divide-shut brake positioner of interior earthed switch of supporting intermediate switchgear cabinet.
Technical background
In on-the-spot Installation and Debugging of electrical power distribution switches cabinet and running,, can cause misoperation if the commissioning staff is unfamiliar with for the operation sequence of switch cubicle.And switch cubicle prevents the earthed switch divide-shut brake positioner that misoperation is used at present, earthed switch divide-shut brake corner can not be limited in the desired 90 ° of scopes of switch, when the earthed switch divide-shut brake has put in place, the earthed switch operation axis still can continue rotation, will cause misoperation like this, also can cause some damage of components in the cabinet simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of can be limited in earthed switch divide-shut brake corner 90 ° of earthed switch divide-shut brake positioners in the scope.
The technical solution adopted in the utility model is: a positioning sleeve that 180 ° of boss are arranged is set, the positioning pedestal that 90 ° of boss are arranged, positioning sleeve and positioning pedestal are set on the earthed switch operation axis, and positioning sleeve is fastened on the earthed switch operation axis, positioning pedestal is fixed on the switch cubicle column, positioning sleeve and positioning pedestal cooperate, and the anglec of rotation that makes positioning sleeve is 90 °.
Because the divide-shut brake corner of earthed switch is 90 °, the utility model earthed switch divide-shut brake positioner positioning pedestal is fastened on the switch cubicle column, therefore, earthed switch also can only half-twist, thereby realize the location, earthed switch divide-shut brake corner is limited in the desired 90 ° of scopes of switch, effectively avoids because the commissioning staff not too understands for the switch cubicle operation sequence and causes misoperation.Rational in infrastructure, easy for installation, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model earthed switch divide-shut brake positioner;
Fig. 2 is the A-A profile when being in the separating brake position embodiment illustrated in fig. 1;
Fig. 3 is the A-A profile when being in closing position embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, earthed switch operation axis 2, positioning sleeve 3, positioning pedestal 4, Elastip pin 5, bolt 6, switch cubicle column
As shown in the figure, positioning sleeve 2 has one 180 ° boss, positioning pedestal 3 has 90 ° of boss, positioning sleeve 2 and positioning pedestal 3 are set on the earthed switch operation axis 1, positioning sleeve 2 is fastened on the earthed switch operation axis 1 by Elastip pin 4, positioning pedestal 3 is fastened on the switch cubicle column 6 by bolt 5, and positioning sleeve 2 and positioning pedestal 3 cooperate, and the anglec of rotation that makes positioning sleeve 2 is 90 °.Because the divide-shut brake corner of earthed switch is 90 °, therefore, earthed switch also can only half-twist.
Claims (1)
