For marketing work, panel switches monitor terminal needs it to draw remote signal line to on-pole switch, in this way We can issue trip command to a defaulting subscriber distant place by power user power consumption information acquisition system and urge expense to reach Effect, while human cost has also been saved to a certain extent.But during specifically used, some electrical power user's malice is pressed from both sides Disconnected FTU is drawn to the control line of on-pole switch, causes us that can not carry out transfer trip to this client.
Utility model content
To be solved in the utility model is that power consumer malice pinch off FTU is drawn to the control line of on-pole switch, is caused The technical issues of we can not carry out transfer trip to this client is, and it is an object of the present invention to provide a kind of panel switches monitor terminal controls Wire clamp breaks prior-warning device.
The utility model is achieved through the following technical solutions:
A kind of panel switches monitor terminal control line pinch off prior-warning device, including on-pole switch and panel switches monitoring are eventually The operating mechanism of end, the panel switches monitor terminal and on-pole switch passes through control cable connection, panel switches monitor terminal It further include the signal generator alarmed of having no progeny control cable clip, institute for controlling the automatic breaking-closing operating of on-pole switch Stating signal generator includes power supply, resistance R1, resistance R2, current comparator, and the resistance R1 and resistance R2 are connected in series, resistance One end of R1 is electrically connected to a power source, and the first input end of one end of resistance R2 and current comparator connects, and the of current comparator The connection of the cathode of two input terminals and power supply, the output end of the current comparator and the communication terminal electricity of panel switches monitor terminal Connection, the control cable include pilot and detection conducting wire, and pilot is used for the division panel switches monitor terminal Lock signal passes to the operating mechanism of on-pole switch, and detection conducting wire is shorted at the both ends of resistance R1 or resistance R2, and the control is led Line and detection conducting wire form quad.
The outer wall of preferred embodiment, the quad is enclosed with insulating layer, is enclosed between insulating layer and quad Metal tape.
Preferred embodiment, the quad are set in rigid casing, and the rigid casing is steel pipe.
Preferred embodiment, the signal generator are located in panel switches monitor terminal.
Preferred embodiment, the power supply are battery.
Preferred embodiment, the on-pole switch are vacuum circuit breaker, and the operating mechanism is permanent magnet mechanism.
The utility model compared with prior art, has the following advantages and benefits: one kind of the use of the new type is matched Electric switch monitor terminal control line pinch off prior-warning device, the device are provided between on-pole switch and panel switches monitor terminal Cable and signal generator are controlled, controlling in cable includes two pilots and two detection conducting wires, wherein two controls are led Line is used to the divide-shut brake signal of panel switches monitor terminal pass to the operating mechanism of on-pole switch, is controlled by pilot On-pole switch breaking-closing operating processed.Two detections conducting wire therein is connect with signal generator, set in signal generator there are two Concatenated resistance and current comparator and battery, the both ends of two detection conducting wires and any one progress in two concatenated resistance It is shorted, detects the another shorted on both ends of conducting wire.When controlling cable not by pinch off, the constant current hold of signal generator, electricity It flows comparator and does not export alarm signal to panel switches monitor terminal, when controlling cable by pinch off, the electric current of signal generator Become smaller, current comparator exports alarm signal to panel switches monitor terminal, and power supply department can find the control of the user in time Cable status processed is abnormal, carries out in-situ processing in time.
Detailed description of the invention
Attached drawing described herein is used to provide to further understand the utility model embodiment, constitutes the one of the application Part does not constitute the restriction to the utility model embodiment.In the accompanying drawings:
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached drawing, The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this Utility model is not intended to limit the scope of the present invention.
Embodiment
As shown in Figure 1, a kind of panel switches monitor terminal control line pinch off prior-warning device of the utility model, including opened on column It closes and panel switches monitor terminal, panel switches monitor terminal can be communicated with a distant place with electronic station, by the fortune of controller switching equipment Row data are sent to electronic station, can also be received the control command with electronic station, be controlled controller switching equipment and adjusted.Match The operating mechanism of electric switch monitor terminal and on-pole switch is by control cable connection, and panel switches monitor terminal is for controlling column The automatic breaking-closing operating of upper switch.It further include the signal alarmed of having no progeny control cable clip in panel switches monitor terminal Generator.
