Knife switch is with moving contact-plug-in strip, and by it with the fixed contact on base-cutter holder base phase wedging or be separated, to connect or a kind of switch of point deenergizing.Being widely used of knife switch, is usually used in: insulating power supply, to guarantee the safety of circuit and maintenance of equipment; Or as the load disjunction load of infrequently connecting and below disjunction rated current, as infrequently connection and the little low-voltage circuit of breaking capacity or directly start small-capacity motor.
In use, knife switch after combined floodgate is due to the Action of Gravity Field of plug-in strip, after long-time, plug-in strip can slowly be deviate from from fixed contact, causes power-off, especially for the electric power system of pipeline-type, if generation breaking, will cause to produce and interrupt, and even can cause damage to production equipment, therefore, a kind of knife switch preventing breaking is needed.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of dual control knife switch, comprises dual plug-in strip, prevent plug-in strip under long-time "on" position due to self gravitation breaking, thus avoid breaking on the impact of production equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of dual control knife switch, comprise insulation bearing, longitudinal plug-in strip and fixed contact, one end of described longitudinal plug-in strip is articulated with the middle part of described insulation bearing, the other end is provided with operating handle, and described fixed contact is arranged at the side of described longitudinal plug-in strip and is fixed in described insulation bearing;
Also comprise horizontal plug-in strip, one end of described horizontal plug-in strip is articulated with the edge of described insulation bearing, the other end is provided with handle, and its knife face can be covered in directly over described fixed contact and described longitudinal plug-in strip, the knife face insulation of described horizontal plug-in strip, and its knife face is provided with the connecting key for holding out against described longitudinal plug-in strip and described fixed contact.
It is insecure with the contact of described fixed contact after described longitudinal plug-in strip closes a floodgate, described fixed contact and described longitudinal plug-in strip can be held out against further by the combined floodgate of horizontal plug-in strip, horizontal plug-in strip can not due to Action of Gravity Field breaking, therefore ensure that the longitudinal plug-in strip not breaking under its knife face.
Wherein, in order to ensure horizontal plug-in strip not breaking further, described handle is provided with snap ring, described insulation bearing is provided with corresponding buckle.The cooperation of snap ring and buckle, achieves the locking action to horizontal plug-in strip.
Further, in order to ensure that longitudinal plug-in strip intended trajectory longitudinally when closing a floodgate closes a floodgate, the both sides of described longitudinal plug-in strip are provided with the longitudinally guiding groove of fitting with its knife face.
Further, rock to prevent the longitudinal plug-in strip after closing a floodgate from producing, described insulation bearing is also provided with longitudinal plug-in strip limiting stand, and described longitudinal plug-in strip limiting stand is relative with described fixed contact, and is close to the another side of described longitudinal plug-in strip.Be clipped between described longitudinal plug-in strip limiting stand and described fixed contact after longitudinal plug-in strip closes a floodgate, can not occur significantly to rock.
Further, in order to ensure the safety of operating personnel, described operating handle and handle are provided with insulating barrier.
Further, described insulation bearing is also provided with ground connection static contact seat, improves fail safe of the present invention.
The advantage that the utility model has and good effect are: adopt the mode that longitudinal plug-in strip and horizontal plug-in strip coordinate, achieve the two ore control of knife switch, prevent longitudinal plug-in strip in long-time use procedure, due to self gravitation effect, breaking occurs, and add the combined floodgate limiting component of longitudinal plug-in strip, ensure that the stability after longitudinal plug-in strip combined floodgate.The utility model is rational in infrastructure, and fail safe is high, easy to use.
