Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide that a kind of volume is littler, structure is simpler, management maintenance is more convenient, but has the monomer-type fire monitor of the various functions of general fire-disaster monitoring device.
For achieving the above object; the present invention adopts a kind of monomer-type fire monitor; comprise power panel, signal sampling plate, backlight, master control borad, zero sequence current mutual inductor, protective circuit breaker, signal terminal and insulation crust; signal terminal is contained in insulation crust one side, and other various mentioned components all is contained in the insulation crust.
The present invention all is contained in power panel, signal sampling plate, master control borad, zero sequence current mutual inductor, protective circuit breaker in the insulation crust; signal terminal is attached to the insulation crust side; form integral structure; and saved the housing of former circuit breaker; layout is quite reasonable, makes whole fire monitor volume-diminished, and structure is simpler; management maintenance is also more convenient, does not but influence whole function of use.
The present invention further is set to insulation crust and comprises at the bottom of casing cover, the shell; two ends at the bottom of shell are provided with the turnover line terminals; into and out of between the line terminals protective circuit breaker is housed at the bottom of the shell; be provided with dress plate chamber on the next door of protective circuit breaker, between protective circuit breaker and input terminal or outlet terminal, be provided with the instrument transformer chamber.
The present invention further is set to power panel, signal sampling plate, backlight, master control borad pad, and all to be contained in the dress plate of outer casing bottom indoor, and it is indoor that zero sequence current mutual inductor is contained in the instrument transformer of outer casing bottom.
The present invention further is set to comprise on the power panel accurate converter, power module, filter.Line voltage distribution can be exported usefulness after step-down, rectification, filtering, voltage stabilizing, voltage sampling signal also is provided simultaneously for the power supply of fire monitor control circuit.
The present invention further is set to the signal sampling plate and comprises operational amplifier, miniature relay, temperature sensitive resister.The signal sampling plate can amplify shaping with various signals such as the temperature that collects, leakage current, overvoltage, under-voltage, the phase failure, Voltage unbalances, and output is for the usefulness of master control borad analysis.
The present invention further is set to master control borad again and comprises display screen, display driver chip, single-chip microcomputer, key is set.The various signals that master control borad can provide according to the signal sampling plate and the various Control Parameter of fire monitor setting are calculated comparison; if any unusually; output control signals to protective circuit breaker, simultaneously various running parameters such as the electric current in the real-time circuit, voltage, temperature, phase place on the display screen.
Zero sequence current mutual inductor of the present invention can collect electric leakage, the phase failure and Voltage unbalance etc. for information about from supply line, for the usefulness of signal sampling plate.Protective circuit breaker wherein, it can be according to the rapid open-circuit line power supply of protection trip signal of master control borad output, realizes supply line is taken place or the usefulness of power-off protection that will breaking out of fire.Wherein signal terminal can play the function served as bridge of acknowledge(ment) signal and output signal, and linking to each other with host computer communicates, and constitutes a fire distributed monitoring system, simultaneously, but the also unit use of this fire monitor.
