Abstract
The utility model relates to a voltage monitoring alarm used for a jail power grid. The voltage monitoring alarm used for the jail power grid is used for realizing real-time monitoring of working states of the jail power grid. The voltage monitoring alarm used for the jail power grid provided by the utility model includes a programmable controller installed in a monitoring chamber and a voltage sensor installed beside a power grid feeder line. A signal output terminal of the voltage sensor is connected to the programmable controller through a protection circuit, a current/voltage converting circuit and a signal processing circuit. A control signal output terminal of the programmable controller is connected with a field sound-light alarm device. The voltage monitoring alarm used for the jail power grid provided by the utility model has advantages that a real working state of the power grid can be reflected accurately, so that potential safety hazards in management are avoided; needs for multi-stage monitoring can be met through alarming through sound and light in a field and uploading alarm signals; and circuit of the voltage monitoring alarm used for the jail power grid can be detected through self-checking, so that equipment faults can be found timely and operational reliability is improved.
Description
Technical field
The utility model relates to a kind of prison line voltage monitoring alarmer that the duty of prison electrical network is monitored in real time of being used for.
Background technology
The prison electrical network is being born important guard task, the dead electricity fault that the prison electrical network is taken place can the time to find and handle be the important duty of prison administration.But in the existing prison operation of power networks process, the guard personnel only judge by the switch deciliter situation of electric power system whether electrical network is charged, and difficulty is made accurate judgement to the true charged situation of electrical network, thereby exists managerial leak and hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of prison line voltage monitoring alarmer that can accurately monitor and warn the duty of prison electrical network is provided.
Prison of the present utility model line voltage monitoring alarmer includes the Programmable Logic Controller that is installed in Control Room and is installed in the other voltage sensor of electrical network feeder line; the signal output part of voltage sensor is connected to Programmable Logic Controller through input protection circuit, current/voltage translation circuit and signal processing circuit, and the Controlled by Programmable Controller signal output part is connected with on-the-spot acoustic-optic alarm.
The control signal output ends of described Programmable Logic Controller also connects remote alarming system by signal cable.
Prison of the present utility model line voltage monitoring alarmer also includes the selftest module that can simulate alerting signal, and the signal output part of selftest module is connected to signal processing circuit and Programmable Logic Controller, with the output self-test signal.
The utility model has the advantages that: 1, utilize Programmable Logic Controller and peripheral sensor and signal processing circuit directly the voltage of prison electrical network to be monitored, can react the real work state of electrical network more accurately, avoided safety management hidden danger; 2,, can satisfy the needs of multilevel monitor by on-the-spot sound and light alarm with upload alerting signal; 3, can detect self Circuits System by self check, in time the discovering device fault has improved operational reliability.
