Abstract
The utility model relates to a DC insulation online monitoring device for a transformer substation. The DC insulation online monitoring device is composed of a field monitoring module, a communication module and a monitoring system, wherein the modules are fixedly connected with each other through a circuit. The DC insulation online monitoring device is characterized in that the field monitoring module comprises a signal voltage collection module, a signal current collection module, a data processing restriction module, a data output module and a data display module; the communication module comprises a data output module, a serial server and an electric power system intranet; and the monitoring system comprises a database, an alarm device, a computer monitor and a field monitoring display. The DC insulation online monitoring device provided by the utility model has the beneficial effects that a module of the system gives out an alarm when a ripple factor is too high or alternating current intrudes into a direct current system, or when the ripple factor of output voltage exceeds the standards, and an alarm signal is transmitted to a remote office host through a network at the same time, thereby providing a basis for troubleshooting. The condition that alternating current intrudes into direct current in the direct current system can be monitored in real time.
Description
Technical field:
The utility model relates to a kind of direct supply Intelligent monitoring device, belongs 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.Exist wearing and tearing or mis-wired phenomenon or manual operation careless due to the alternating current-direct current cable in long-time running, can cause to exchange and scurry into direct current.Cause the flow directing device warning, can cause device damage even to protect 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 meeting this requirement, the Te Famingben device.
Summary of the invention:
The purpose of this utility model is to provide a kind of transforming plant DC insulation line monitoring device, can monitor in straight-flow system and exchange and scurry into direct current, reports to the police when having interchange to scurry into straight-flow system, and records ripple.Can monitor simultaneously the ripple factor size of floating machine output voltage.
The utility model is achieved through the following technical solutions its goal of the invention.
A kind of transforming plant DC insulation line monitoring device consists of field monitoring module, communication module, supervisory system, be connected by circuit between module and 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 monitoring to exchange after scurrying into direct current.According to the sampled voltage data, to the ripple collection repeatedly, average, calculate the output voltage ripple coefficient.
Effective effect of the present utility model is: it is too high or have and exchange while scurrying into straight-flow system that this system can be worked 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 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 the utility model structural representation.
Accompanying drawing 2 is the utility model module principle figure.
Embodiment:
The utility model is described in further detail 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 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;
