Description
Technical field
The utility model relates to a kind of isolation switch device being applicable to track traffic tractive power supply system, specifically a kind of direct current two station disconnecting switch operational lock device of DC traction switch cubicle.
Background technology
Along with track traffic development at home, the focus that user pays close attention to realizes shifting to security of system from technical performance gradually.Traditional DC power-supply system many employings isolating switch when needs electrical isolation fracture realizes, and in order to save cost, is often directly hung in tunnel wall by isolating switch, and this brings hidden danger safely to the life of electric power system and operating personnel.Therefore in today that city rail tractive power supply system is day by day ripe, the many considerations of user adopt and the isolation switch device of enough degree of protection can be provided to carry out alternative traditional scheme, at present, the isolation switch device that each manufacturer of track traffic industry produces is all by winning the market to the architecture advances of isolation switch device, but because structure is comparatively simple, ubiquity degree of protection is low, the problems such as electrical security is not enough, how on the basis reducing maintenance cost, the security reliability of simple and effective raising isolation switch device becomes the focus paid close attention in the industry.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple and reliable for structure and can improve the direct current two station disconnecting switch operational lock device of isolation switch device degree of protection and electrical security.
In order to solve the problems of the technologies described above, direct current two station disconnecting switch operational lock device of the present utility model, comprise switch cabinet body, cabinet door on cabinet and two station disconnecting switchs be vertically fixedly mounted in the middle part of cabinet body frame, the peripheral fitting insulating panels of two station disconnecting switchs, the handle hole of rear proper contraposition on cabinet door of the operation axis of two station disconnecting switchs, an operating grip can extend in handle hole and operate two station disconnecting switchs, cabinet door is provided with the operational lock device being positioned at handle hole side, described operational lock device comprises the lock operation end controlled by key and the butterfly be connected on lock operation end, butterfly can block handle hole along the center rotating of lock operation end or leaves handle hole.
Cabinet door is provided with the second locking column being positioned at the first locking column on horizontal level and being positioned on vertical position, butterfly has a bayonet socket, butterfly can two locking columns spacing under rotate between horizontal level and vertical position; Make when butterfly is positioned at horizontal level the lower surface of butterfly spacing on the first locking column, can handle hole be blocked when butterfly is positioned at vertical position and make bayonet socket spacing at the second locking column.
Described cabinet door is provided with the observation window being convenient to observation two station disconnecting switch deciliter state.
After adopting said structure, due to the operational lock device that cabinet door is arranged, necessary first rotation process locking device, expose the handle hole of operational lock device, update handle, ability deciliter two station disconnecting switchs, improve the electrical security of two station disconnecting switch devices, the peripheral fitting insulating panels of two station disconnecting switchs, further ensure high degree of protection and the class of insulation, its structure is simple, and installation and maintenance are simple, reliability is high, reduces manufacturing cost simultaneously.
