Abstract
The device includes the discharging tubes, the driving cone subassembly and the LED. The said driving cone subassembly is set up in the middle between the two discharging tubes. The spring leaf of the ground wire is set up to contact the driving cone in the subassembly. The spring leaf of the exterior line through the action spring leaf is connected to the discharging tubes. The interior wire spring leaf through the thermistor is connected to the action spring leaf. When the situation of over current and over voltage is occurred, the driving cone turns a certain angle driven by the the spring leaf of the ground wire. Then, the alarm is given out and the exterior line is grounded, turned to the open circuit. The rest of the spring leaf of the ground wire is manhandled. The actions and recovery device can be used repeatedly.
Description
Technical field:
The present invention relates to circuit protection device, particularly a kind of action and recovery device that is used for overcurrent and overvoltage protector.
Background technology:
In the prior art, generally adopt thermistor, the discharge tube protective device as overcurrent, overvoltage protection device, its structure is divided three classes substantially: short-circuit structure, fusible link open-circuit structure and bimetal leaf open circuit/recovery structure.Adopt the protective device of this three class formation to have many limitations in actual applications: the protective device that adopts short-circuit structure, when using in unattended access site, if power line takes place to be touched, the protective device action produces the big electric current in ground, high-current leading plays a large amount of heats, and can't guarantee in-situ processing timely, disaster is difficult to avoid; Adopt the protective device of fusible link open-circuit structure, alarm is finished by two cover independent components with open circuit, outside line and power line touch some the randomness apart from the distance of equipment, the size that decision produces overcurrent on the line is indefinite, yet the length of fusible link operate time directly depends on the size of master stream through electric current, so outputting alarm can't guarantee to open a way the time, can not in time carry out the fault prompting, exist the attendant by the danger of outer line end suspension high voltage injury; Adopt the Security Unit of bimetal leaf open circuit/recovery structure; because of needing electric current, keeps the state after the bimetal leaf action; and after in fact open circuit moves; electric current promptly disappears; so bimetal leaf automatically resets again; produce vibration so repeatedly, cause communication line can't operate as normal and protective device in the premature failure of protection device.The improved structure that manually recovers appears in the back, but needs to increase in addition to promote and slide mechanism, to the protective device adaptive capacity of different structure a little less than.
Summary of the invention:
Technical problem to be solved by this invention is: because available technology adopting thermistor, discharge tube are as the protective device of overcurrent, overvoltage protection device; so can't guarantee in-situ processing timely in use and in time carry out the failure warning prompting; the attendant is constituted very big danger; existing in addition manual recovery mechanism needs to increase in addition to promote and slide mechanism, to the protective device adaptive capacity of different structure a little less than.The present invention provides a kind of action and recovery device that is used for overcurrent and overvoltage protector for the technical scheme that the problems referred to above adopted that solves in the prior art; described this action and the recovery device that is used for overcurrent and overvoltage protector; by housing; two discharge tubes; level wheel assembly and light-emitting diode constitute; wherein; described discharge tube; level wheel assembly and light-emitting diode all are arranged in the described housing; described level wheel assembly is arranged in the middle of described two discharge tubes; contact is provided with a ground wire reed on the step cone in the described level wheel assembly; be connected with an action reed on the described discharge tube; contact is provided with an outside line reed on the described action reed; and be connected with a thermistor on the described action reed; be connected with an interior lines reed on the described thermistor; the positive pole of described light-emitting diode is connected with a signal reed; the negative pole of described light-emitting diode is connected with a signal patch; described signal patch is connected with described housing; concrete; described level wheel assembly can be by step cone; axle is configured to propping up; further; in the described level wheel assembly; described axle is arranged on the support; described axle is provided with step cone; can connect by the soldering syndeton between described step cone and the axle; also can connect between described axle and the support by the soldering syndeton; further again, the progression of described step cone is at least four.Described ground wire reed and described step cone are provided with and are electrically connected, and described step cone and discharge tube are provided with and are electrically connected.
The course of work of the present invention is: when overcurrent, overpressure situation occurring, the ground wire reed promotes step cone and turns an angle, and ground wire reed activation signal reed, and then pushing action reed and the disconnection of outside line reed have been realized opening a way after the outside line ground connection.The positive pole of signal reed sending and receiving optical diode, the negative pole of signal patch sending and receiving optical diode has been realized the output of alarm signal.Outline fault manually promotes the ground wire reed and resets after getting rid of, and the recovery of action reed is communicated with the outside line reed, and protective device returns to original user mode.
