Description
Technical field
The utility model relates to a kind of resistor, is specifically related to a kind of intelligent resistance device.
Background technology
When resistor damages because of aging or quality problems, not only can affect the safe operation of electric power system, and be difficult for from external inspection to, be difficult to find in the short period of time abort situation, can not change in time resistor, bring very large trouble to the maintenance of system.
At present when resistor is detected, general employing is manually carried instrument (temperature measuring device, current tester, infrared ray tester etc.) and directly at operation field, is carried out, which not only wastes time and energy, and also operating personnel's safety is produced to certain hidden danger; In order to address the above problem, when carrying out testing current, technical staff has also adopted real-time current testing equipment has directly been installed on resistor, and by modes such as liquid crystal display, carry out current value and export in real time, but which is owing to being mostly to utilize the signal of telecommunication to transmit test result, the electric radiation producing while easily being worked by resistor self is disturbed, thereby causes test result to depart from the problem of true value; Meanwhile, comparatively complexity is installed in the resistor box that existing testing current equipment and line thereof are installed at resistor or other shells, takies larger space, also improved operating cost; Therefore, be badly in need of providing a kind of simple in structure, reliability is high, functional strong real-time monitoring instrument is monitored resistor.
Summary of the invention
The utility model provides a kind of intelligent resistance device, has mainly solved in prior art, can not be out of service in time when resistor damages, and cannot carry out Real-Time Monitoring to resistor, can not the contingent fault of reliable prediction etc. problem.

This intellectuality resistance device comprises at least one resistance unit, and resistance unit is arranged in housing by fixture, also comprises fibre-optical probe, and fibre-optical probe one end is connected with resistance unit, and the other end is connected with monitoring alarm device one end by optical fiber.
Above-mentioned fixture is insulation column, and housing is metal safe or metal can; Resistance unit two ends are fixedly connected with insulation column respectively.
Above-mentioned fixture is insulating bar and holding electrode, and housing is metal can or insulating coating; Resistance unit is fixed in housing by holding electrode and insulating bar.
Above-mentioned fibre-optical probe is big or small for monitoring resistor cell temperature and/or monitoring resistor cell current, and is transmitted through the fiber to monitoring alarm device after the data that monitor are converted into light signal.
Above-mentioned monitoring alarm device is sound, the warning device such as optical, electrical.
The above-mentioned monitoring alarm device other end is connected with resistor by electric control system, can be by control switch, resistor is out of service while needing.
The utility model has the advantage of:
1. by temperature and/or current monitoring, can be promptly and accurately the running status of monitoring resistor device reliably, avoid resistor aging or cause the system failure after damaging because of quality problems.
2. by optical fiber, carry out the transmission of resistor temperature value and/or current value, avoided as much as possible the impact of resistor internal electromagnetic on stable signal transmission, meanwhile, effectively improved the transmission rate of signal.
3. fibre-optical probe is arranged on resistance unit, is easy to improve the accuracy of monitoring, guarantee that the resulting data of monitoring are substantially equal to true value.
