Abstract
A switch cabinet monitoring device provided by the utility model relates to a power equipment monitoring device, especially to a switch cabinet monitoring device. The switch cabinet monitoring device provided by the utility model is characterized by comprising a power module, a signal collector, a transmission module, a signal processing module, an output module and a display module, wherein the power module, the signal collector, the transmission module, the signal processing module and the output module are connected in order; and the display module is connected on the signal processing module. According to the switch cabinet monitoring device, low current on equipment is acquired by the signal collector, and the current is transmitted to a singlechip for analysis processing; and when the current exceeds a set threshold current, an alarm sounds. Workers can monitor status of equipment all the time through the monitoring device. The switch cabinet monitoring device provided by the utility model has advantages of simple structure and strong practicality.
Description
Technical field
The utility model relates to a kind of power equipment monitoring device, particularly a kind of monitoring device of switch cubicle.
Background technology
High-tension switch cabinet is the core component of electric system; it is take isolating switch as main electrical equipment; mainly being comprised of electric utilities such as control section, protection part, measure portion, bus, conductor, insulators, is to accept and distribute the device of electric energy in electric system.Along with increasing of primary equipment in cabinet, secondary device also increases thereupon, along with long use, the decreasing insulating of circuit, cabinet exist larger potential safety hazard, when cabinet breaks down, without any the warning measure, easily primary equipment is caused larger infringement, if while operating personnel close cabinet under ignorant situation easily causes personal safety larger infringement to occur.
Summary of the invention
The utility model proposes a kind of device of switch cubicle being realized safety monitoring.
Switch cubicle safety monitoring assembly described in the utility model, comprise signal picker, transport module, message processing module, output module and display module, wherein signal picker, transport module, message processing module are connected with output module and are connected, and display module is connected on message processing module.
Preferably, described signal picker has a plurality of ports, is equipped with 3 mutual inductors on each port.
Further preferably, described mutual inductor is small coin shape mutual inductor.
Preferably, described transport module comprises operational amplifier and digital to analog converter.
Preferably, also be connected with induction pick-up and temperature sensor on message processing module.
Preferably, described temperature sensor has a plurality of.
Preferably, described display module is liquid crystal display.
Preferably, described output module is alarm.
Preferably, described message processing module is single-chip microcomputer.
Switch cubicle safety monitoring assembly described in the utility model, by the little electric current on the signal picker collecting device, this electric current is sent to the single-chip microcomputer analyzing and processing, when surpassing the threshold current of setting, report to the police, the staff can pass through this monitoring device state of watch-dog constantly, and the utility model is simple in structure, and is practical.
Description of drawings
Fig. 1 is connection diagram of the present utility model.
In figure: the 1-alarm; The 2-signal picker; The 3-operational amplifier; The 4-digital to analog converter; The 5-single-chip microcomputer; The 6-liquid crystal display; The 7-induction pick-up; The 8-temperature sensor.
Embodiment
Switch cubicle safety monitoring assembly described in the utility model, comprise successively connect, signal picker 2, operational amplifier 3, digital to analog converter 4, single-chip microcomputer 5 and liquid crystal display 6, also be connected with induction pick-up 7, a plurality of temperature sensor 8 and alarm 1 on single-chip microcomputer 5; Signal picker 2 described in the utility model has a plurality of ports, is equipped with 3 small coin shape mutual inductors on each port.
this monitoring device is provided with several signals collecting ports, each all can connect the ground wire of a secondary equipment, be used for receiving equipment and get leakage current or insulation current, when signal picker 2 ports monitor electric current and pass through, small current mutual inductor is sensed electric current, this signal is amplified through operational amplifier 3, then pass to digital to analog converter 4, after being become digital signal, it passes to again single-chip microcomputer 5, calculate the size of electric current by single-chip microcomputer 5, and show by liquid crystal and diode lights, as surpassing the threshold current of setting, send control signal to relay, and report to the police by alarm 1, the utility model includes a plurality of temperature sensors 8, the surface of each equipment all arranges one, the warm variate that temperature sensor 8 will detect directly is passed to single-chip microcomputer 5, when induction temperature becomes when surpassing thresholding temperature that single-chip microcomputer 5 sets and becoming, immediately by alarm 1 warning.When induction pick-up was sensed personnel near switch cubicle, range LCD screen lamp was bright, and the staff can obtain desired data by reading liquid crystal display 6.
