Abstract

The utility model relates to a monitor, especially to an intelligent monitor of a transformer substation. The intelligent monitor comprises a housing, an MCU controller, a sensor, a circuit breaker, a display, a network communication interface and a DDC direct input interface, wherein the MCU controller, the circuit breaker, the network communication interface and the DDC direct input interface are installed in the housing. The intelligent monitor is characterized in that the sensor conveys voltage and current signals acquired to the MCU controller which controls the on and off of the circuit breaker according to the voltage and current signals. The MCU controller converts the voltage signals into digital signals which are provided to the display for real time displaying and provided to the network communication interface for remote monitoring by a computer.

Description

The intelligent monitor of transformer station
Technical field
The utility model relates to a kind of watch-dog, especially a kind of intelligent monitor of transformer station.
Background technology
Harm in transformer station for faults such as protection supply line and power-supply device are avoided transshipping, under voltage, short circuit, single-phase earthings arranges a kind of main switch in low-voltage distribution cabinet, be used for the low voltage power distribution network of control and protection rated current 630A~6300A.What existing main switch was more advanced is that intelligent universal circuit breaker has the intelligent protection function, and selective protection is accurate, can improve power supply reliability, simultaneously with open communication interface, can be connected with host computer, carries out remote control, remote regulating etc.Its intelligent controller has overload long delay inverse time lag, short time delay inverse time lag, specified time, instantaneous function; Also have simultaneously the Presentation Functions such as setting current demonstration, operating current demonstration, each line voltage demonstration, overload-alarm function, the self-checking functions such as overheated self check, microcomputer self diagnosis.
Although intelligent universal circuit breaker has had the function of control and protection low voltage power distribution network; but lack monitoring function; if will carry out on-line monitoring and harmonic analysis to circuit; so also need to increase many monitoring instruments and instrument; this not only will enlarge the volume of low-voltage distribution cabinet, and more can greatly increase the complexity of cost and installation.Now in low voltage power distribution network, along with developing rapidly of power electronic technology, non-linear negative cutting come into operation in a large number, produces the higher harmonic current of amplitude, harmonic problem is on the rise in transformer station, and transformer station and power consumption equipment have been produced serious harm and impact.
The utility model has carried out useful improvement in order to overcome defects.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of intelligent monitor of transformer station is provided.
The purpose of this utility model is to realize the electric current of transformer station, the monitoring of voltage, and can realize Long-distance Control by transducer, MCU controller.
to achieve these goals, the technical solution of the utility model is: a kind of intelligent monitor of transformer station, comprise shell, the MCU controller, transducer, circuit breaker, display, network communication interface, the direct input interface of DDC and keyboard, described MCU controller, circuit breaker, network communication interface, the direct input interface of DDC is arranged on described enclosure, it is characterized in that: described transducer obtains voltage, be transferred to the MCU controller after current signal, described MCU controller is according to voltage, current signal is controlled the break-make of circuit breaker, described MCU controller is converted to digital signal with voltage signal and offers display and show in real time, offer described network communication interface and be used for the computer remote monitoring.
Further, the MCU controller is the MC68HC908GT16 single-chip microcomputer.
The beneficial effects of the utility model: compared with prior art, the utility model mutually combines power network monitoring, Long-distance Control and intelligent breaker, take MCU as core, real available value of voltage, electric current real effective etc. is monitored, each parameter can show in real time by the form of LED liquid crystal display with data and waveform, the playback online of record waveform also can upload to computer by network interface, and is very important to the safe operation of guaranteeing transformer station.
