Abstract
The utility model discloses an intelligent low-voltage switch cabinet for remote control failure alarming, which consists of a cabinet body, a main power supply circuit, a circuit breaker, on/off coils of the circuit breaker, a contact position of the circuit breaker, distribution switches, coils of the distribution switches, contact positions of the distribution switches, transformers, a PLC (Programmable Logic Controller) communication unit and an RS-485 bus. The intelligent low-voltage switch cabinet is characterized in that after connected with the circuit breaker in series, the main power supply circuit is connected with the plurality of distribution switches in parallel, and then connected with a distribution line in series. Both the circuit breaker and the distribution switches are provided with the current transformers, the on/off coils of the circuit breaker and the coils of the distribution switches are respectively connected with an I/O output port of a PLC; the contact position of the circuit breaker and the contact positions of the distribution switches are respectively connected with an I/O input port of the PLC, and the PLC is connected with an upper computer through the RS-485 bus. The intelligent low-voltage switch cabinet has the advantages of safety, rapidness, reliability and wide application range.
Description
Technical field
The utility model relates to Long-distance Control, detection technique field, is specifically related to the malfunctioning warning intelligent low-pressure of a kind of remote control cabinet.
Background technology
Traditional low-voltage cabinet is to adopt on-the-spot button, switch direct control, can't realize computerized intelligent management.The on off operating mode of each panel switches, warning message, all can't show and file inquiry, more can't control and monitor by remote mode.Both having made is the power distribution cabinet that has remote mode to control, its verification command passes down whether accurately mode adopts identifying code often on software mode, but this mode but can not solve when secondary line in the power distribution cabinet breaks down (for example: the damage of panel switches coil, main contacts burn out and can not reset), finds guilty culprit in the very first time.For solving above defective, the technical staff has proposed the malfunctioning warning intelligent low-pressure of a kind of new remote control cabinet.
The utility model content
The purpose of this utility model is for solving above defective, the malfunctioning warning intelligent low-pressure of a kind of remote control cabinet is proposed, this intelligent low-pressure cabinet utilizes PLC to carry out data acquisition and processing (DAP), and then has whether normal closed loop detects and warning function to each Long-distance Control electric switch work.
The utility model is the malfunctioning warning intelligent low-pressure of an a kind of remote control cabinet, it is made up of cabinet, mains supply line, circuit breaker, panel switches, current transformer, plc communication unit and RS-485 bus, it is characterized in that: mains supply line is with after circuit breaker is connected, with after the panel switches of a plurality of parallel connections are connected, connect with distribution line at last again.Be equipped with current transformer on circuit breaker, the panel switches, the combined floodgate of circuit breaker and switching winding, panel switches coil inserted the I/O output port of PLC respectively; Circuit breaker position contact, panel switches position contact are inserted the I/O input port of PLC respectively, and PLC is connected with host computer by the RS-485 bus.
The malfunctioning warning intelligent low-pressure of this remote control cabinet can utilize PLC to carry out collection, the processing of data, and carries out communication by RS-485 bus and host computer.Realize passing under the host computer control command and cabinet in the uploading of each panel switches status signal, computing and demonstration, when PLC or host computer detect the execution result of remote control command and system when different, report to the police at once, make operation or administrative staff can in the very first time, find guilty culprit, be a kind of to each Long-distance Control electric switch work of power distribution cabinet whether normal closed loop detect and the intelligent low-pressure cabinet of warning function.
Utilization of the present utility model is as shown in Figure 2:
1, when operating personnel need (for example: when KM3) carrying out closed procedure, as long as click pairing remote control command mouse on the host computer interface, remote control command reaches PLC by the RS-485 bus to certain panel switches.
2, PLC is through computing, drive the PLC correspondence the I/O output port make output relay closure (Q0.3=1 this moment).
3, connect the coil KM3 of corresponding panel switches through secondary line, its main contacts closure, distribution wire rood; This panel switches position contact KM3 closure simultaneously.
4, contact KM3 in panel switches position connects the I/O input port (I0.3=1 this moment) of PLC correspondence, PLC reaches host computer with the status signal of input and output point and compares and show, through computing (Q0.3=1 just often, I0.3=1), system normally moves; If note abnormalities (for example: when the output port secondary line of PLC correspondence and components and parts break down, Q0.3=1, I0.3=0), system reports to the police immediately, and the fault coverage of display alarm and time of fire alarming.
The utility model and prior art relatively have safety, quick, reliable, advantage applied widely.
