Abstract
The utility model discloses a breaker overstroke on-line monitoring device. The breaker overstroke on-line monitoring device comprises an insulating pull rod (2), one end of the insulating pull rod (2) is equipped with an insert (1), and the other end is a hollow structure. A compression spring (3) and a self-recovery displacement sensor (4) are arranged inside the hollow structure, and the end part of the sensor (4) is equipped with a connecting rod (5). A sensor lead (6) is led out from the interior of the connecting rod (5), and the material of the insulating pull rod (2) is a sheet-like unsaturated polyester film plastic. According to the breaker overstroke on-line monitoring device having the above structure, and by placing the displacement sensor in the insulating pull rod of a breaker, the compression amount of the compression spring can be embodied by the displacement amount of the displacement sensor after each time of closing, and then the compression amount is transmitted to an intelligent display terminal, thereby realizing the real-time monitoring of the breaker overstroke. The breaker overstroke on-line monitoring device is suitable for a spring operating mechanism, and is also suitable for a permanent magnetic operating mechanism.
Description
Technical field
The utility model relates to a kind of isolating switch over travel on-Line Monitor Device.
Background technology
The effect of isolating switch over travel mainly contain following some: a) ensure contact after electrical wear, still can keep certain contact; B) can utilize touch spring power buffering when contact closure, reduce spring; C) in the time of contact separating brake, make moving contact obtain certain initial kinetic energy, break melting welding point, improve initial opening velocity, reduce the arc time, thereby improve the speed of medium recovery.If the excess of stroke is too little, just can not ensure contact due contact pressure after scaling loss, meanwhile, initial opening velocity diminishes, and can affect breaking and making and the dynamic and thermal stability performance of vacuum switch, even produces reclosing springing.If the excess of stroke is too large, can increase the combined floodgate merit of operating mechanism, making to close a floodgate becomes extremely unreliable.
Existing isolating switch has test report in dispatching from the factory, and the over travel while having dated isolating switch to dispatch from the factory in report, but while moving at the scene, after isolating switch deciliter, can not realize the Real-Time Monitoring to isolating switch over travel.In order better to grasp the performance of isolating switch, be badly in need of the over travel of isolating switch to carry out Real-Time Monitoring.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of isolating switch over travel on-Line Monitor Device for problems of the prior art, its objective is by the inner installation position of insulated tension pole displacement sensor, realizes the Real-Time Monitoring to isolating switch over travel.
The technical solution of the utility model is that this kind of isolating switch over travel on-Line Monitor Device comprises insulated tension pole, described insulated tension pole, one end inserts is installed, the other end of insulated tension pole is hollow structure, hollow structure inside is provided with Compress Spring and sensor, the end of sensor is provided with connecting link, and sensor lead is drawn from the inside of connecting link.
The material of described insulated tension pole is sheet unsaturated polyester (UP) film plastics.
Described sensor is self-recovering type displacement transducer.
There is this kind of isolating switch over travel on-Line Monitor Device of said structure by place a displacement transducer in the insulated tension pole of isolating switch, just the decrement of Compress Spring after at every turn closing a floodgate can be embodied by the displacement of displacement transducer, then reach intelligent display terminal, thereby realize the Real-Time Monitoring to isolating switch over travel, met the demand that users grasp isolating switch break performance in real time, market outlook are larger; Meanwhile, this kind of over travel on-Line Monitor Device is not only applicable to spring operating mechanism, and is applicable to permanent-magnet operating mechanism.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1: inserts; 2: insulated tension pole; 3: Compress Spring; 4: sensor; 5: connecting link; 6: sensor lead.
Embodiment
Fig. 1 is structural representation of the present utility model.Structure is known as shown in Figure 1, this kind of isolating switch over travel on-Line Monitor Device comprises insulated tension pole 2, one end of described insulated tension pole 2 is provided with inserts 1, the other end of insulated tension pole 2 is hollow structure, hollow structure inside is provided with Compress Spring 3 and sensor 4, sensor 4 is self-recovering type displacement transducer, and the end of sensor 4 is provided with connecting link 5, and sensor lead 6 is drawn from the inside of connecting link 5.The material of insulated tension pole 2 is sheet unsaturated polyester (UP) film plastics.
The super shape journey of isolating switch is the stroke that after isolating switch dynamic/static contact contact, mechanism continues action, is isolating switch in order to continue reliable combined floodgate in the reliability that ensures to close a floodgate and contact abrasion situation, and its object is to ensure contact pressure, reduces contact resistance.Generally provided by the touch spring being connected with insulated tension pole, the numerical value of over travel is presented as the decrement of insulated tension pole inner spring.So in order to solve a upper problem, the utility model is placed a displacement transducer in the insulated tension pole of isolating switch, and then the decrement of the rear spring of at every turn closing a floodgate is embodied by the displacement of displacement transducer, then reach intelligent display terminal, so just can realize the Real-Time Monitoring to isolating switch over travel, met the demand that users grasp isolating switch break performance in real time, market outlook are larger; Meanwhile, this kind of over travel on-Line Monitor Device is not only applicable to spring operating mechanism, and is applicable to permanent-magnet operating mechanism.
