Abstract

The utility model discloses a protective device for a box-type transformer substation. The protective device comprises a main control component, an analogue quantity input component, a functional module, an operation unit, a power supply, and a switch quantity input-output unit, wherein the power supply is used for supplying power to the protective device for the box-type transformer substation; the functional module is connected with the analogue quantity input component and the switch quantity input-output unit respectively, and the main control component is connected with the analogue quantity input component, the switch quantity input-output unit and the operation unit respectively; the protective device is configured according to the interval units of a primary system, namely, is corresponding to the different power supply objects of the primary system; the protective device finishes protection for the interval units by adopting the two modes of being installed on a high-voltage cabinet in a dispersed manner or being installed in a centralized screen-grouping manner; and the protective device can form a layered and distributed-type comprehensive automation system with a computer system, and can be used for printing accident records, real-time reports and historical reports, thus providing great convenience for management personnel.

Description

The box-type substation protective device
Technical field
The utility model relates to electronic applications, particularly a kind of protective device.
Background technology
Existing box station generally adopts the overcurrent protective relaying device, and relaying protection is the protection to primary equipment, is usually used in inverse time over-current protection, protects single shortage comprehensive.Simultaneously in use overcurrent relay occur easily moving insensitive, life cycle short, the wiring is in disorder, it is big to take up room, there are deficiencies such as obstacle, data are not directly perceived in five realizations of shaking.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of box-type substation protective device.Concrete technical scheme is:
A kind of box-type substation protective device comprises master element, analog quantity input element, functional unit, operating unit, power supply, switching value input element, and described power supply is described box-type substation protective device power supply.Described functional unit links to each other with analog quantity input element, switching value input-output unit respectively, and described master element links to each other respectively at analog quantity input element, switching value input-output unit, operating unit.
Described master element comprises processor of single chip computer, read-only memory, random access memory, and described single-chip microcomputer links to each other with read-only memory, random access memory respectively.
Described functional unit comprises that voltage transformation functional block, low-pass filtering functional block, sampling keep functional block, multipath conversion functional block, analog-digital conversion function piece.
Described switching value input-output unit comprises parallel interface adapter, photoisolator, auxiliary relay.
Described operating unit comprises keyboard, plate key, signal lamp, printer, charactron.Utilize box-type substation protective device of the present utility model, its beneficial effect is:
Press unit, the interval configuration of primary system, i.e. the different power supply object of corresponding primary system.
Adopt and disperse to be installed on the high-voltage board or concentrated group screen installation dual mode, finish the protection to this unit, interval.Build and connect through RS485, RS422 port between each device and the host computer; each loop running status and real-time parameter are sent on the host computer; realization is to telemeasurement, monitor log, the remote operation of system; be remote measurement, remote control, remote signalling; and record trouble parameter and waveform etc.; wherein divide extracting, gathering in when sampling with metering signal and the guard signal of electric current, with the precision of assurance measurement parameter.Can constitute the layered distribution type complex automatic system with computer system, energy printing problem record, real-time form, history report is for administrative staff provide very big convenience.
