Abstract

The invention relates to a direct current insulation on-line monitoring device of a transformer substation, and the device comprises an on-site monitoring module, a communication module and a monitoring system; the modules are fixedly connected by circuits; the device is characterized in that the on-site monitoring module comprises a signal voltage acquisition module, a current acquisition module, a data processing restriction module, a data output module and a data display module; the communication module outputs data to a serial server and the intranet of a power system; and the monitoring system comprises a database, an alarm device, a computer monitor and a field monitoring display. The direct current insulation on-line monitoring device of the transformer substation has the beneficial effects that the module can give alarm when the ripple factor of the system is too high, alternating current flows into a direct current system or the ripple factor of output voltage exceeds the standard; and meanwhile, an alarm signal is transmitted to a remote office host via Internet, so as to provide a basis for troubleshooting. The inflow of alternating current to the direct current system can be monitored in real time.

Description

A kind of transforming plant DC insulation line monitoring device
Technical field:
The present invention relates to a kind of direct supply Intelligent monitoring device, belong to direct current (DC) monitoring device.
Background technology:
Operation plays most important effect to DC power system to substation safety, and it provides power supply for equipment such as signalling arrangement, protective device, circuit-breaker switching on-off operation, illuminations.Because the alternating current-direct current cable exists wearing and tearing or mis-wired phenomenon or manual operation careless in long-time running, can cause to exchange and scurry into direct current.Cause the flow directing device warning, can cause device damage even protection equipment malfunction when serious, operation brings and has a strong impact on to substation safety.In State Grid Corporation of China's new " 18 great anti-accident measures of electrical network " (revised edition), 5.1.18 explicitly points out and " is strictly on guard against to exchange and scurries into the DC Line Fault appearance simultaneously." simultaneously 5.1.13 require floating machine output voltage ripple coefficient to be not more than 0.5%, for satisfying this requirement, the Te Famingben device.
Summary of the invention:
The purpose of this invention is to provide a kind of transforming plant DC insulation line monitoring device, can monitor to exchange in the straight-flow system and scurry into direct current, when having interchange to scurry into straight-flow system, report to the police, and record ripple.Can monitor simultaneously the ripple factor size of floating machine output voltage.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of transforming plant DC insulation line monitoring device is made of field monitoring module, communication module, supervisory system, be connected by circuit between module and the module, it is characterized in that: the on-site supervision module comprises the signal voltage acquisition module and current acquisition module, data are processed restriction module, data outputting module, data disaply moudle; Communication module data outputting module serial server and electric system Intranet; Supervisory system comprises database, warning setting and computer monitor and field monitoring display.
Its concrete grammar is: at VD end erecting stage acquisition module, be connected to background monitoring by communication module and calculate and scurry into alternating voltage, judge, report to the police, record ripple after scurrying into direct current monitoring to exchange.According to the sampled voltage data, to the ripple collection repeatedly, average, calculate the output voltage ripple coefficient.
Effective effect of the present invention is: it is too high or have and exchange when scurrying into straight-flow system that this system can work as ripple factor, when perhaps the output voltage ripple coefficient exceeds standard, module is sent warning, by network alerting signal is reached long-range office main frame simultaneously, the direct current maintainer receives alerting signal, search alternating current source to the scene and record the DC bus-bar voltage waveform, for malfunction elimination provides foundation.System directly accesses office, can the Real-Time Monitoring straight-flow system exchange the direct current situation of scurrying into.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is module principle figure of the present invention.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
A kind of transformer station direct current system insulation line monitoring device comprises field monitoring module, communication module, supervisory system, be connected by circuit between module and the module, it is characterized in that: described on-site supervision module comprises at least the signal voltage acquisition module and current acquisition module, data are processed restriction module, data outputting module, data disaply moudle;
Described communication module is data outputting module serial server and electric system Intranet at least;
Described supervisory system comprises database, warning setting and computer monitor and field monitoring display at least.
