Description
Technical field
This utility model relates to a kind of secondary interlocking mechanism.
Background technology
The secondary interlocking mechanism of high-tension switch cabinet is the interlocking mechanism that the plug of protective breaker can not be extracted when chopper is in operating position.KYN61-40.5 cabinet is widely used in height above sea level 2000 meters-3500 meters in the market, chopper adopts plateau type physical dimension, reason because of dielectric level, chopper producer be generally adopted before without panel type body frame structure for automotive, cause that the secondary interlocking of plain edition KYN61 cabinet cannot be useful on plateau type cabinet.
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is in that to provide a kind of secondary interlocking mechanism suitable in plateau high-pressure switch cubicle.
For achieving the above object, this utility model adopts a kind of secondary interlocking mechanism, including side plate, bolt, Secondary socket, the first pull bar, the second pull bar, arm-tie, baffle plate, extension spring, it is bolted on side plate, Secondary socket is arranged on side plate one end, first pull bar top is stretched in Secondary socket, first pull bar tail end is connected with arm-tie one end, the arm-tie other end and the second pull bar tail end connect, the top of the second pull bar is connected with baffle plate, being hinged in the middle part of arm-tie on bolt, extension spring one end is fixed on side plate, and the other end is connected to arm-tie and the junction of the second pull bar.
This utility model is further arranged on described side plate to be provided with fixing plate, and fixing plate forms spacing hole, and the second pull bar is through in the spacing hole of fixing plate spacing.
This utility model adopts baffle plate to be connected with chopper, when chopper is in operating position, baffle plate is switched off device and pushes front to, pull the second pull bar to move forward, rotated around bolt by arm-tie, make the first pull bar move in Secondary socket, the top of the first pull bar is buckled on the breaker plug in Secondary socket, prevent breaker plug from extracting, eliminate the potential safety hazard of switch cubicle, improve the safety of switch cubicle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model specific embodiment.
