Technical field
The utility model belongs to technical field of power systems, especially a kind of lightning protection device leakage current measurement system.
Background technology
There is certain leakage current in the zinc paste lightning protection device that transmission line of electricity adopts because himself nonlinear resistance property can not guarantee to block contacting of circuit and the earth fully when normal operation.The existence of current in resistance property can cause the heating of zinc paste lightning protection device in this electric current, thereby accelerates the aging and inefficacy of lightning protection device, and the oxidation deactivation of lightning protection device can cause the increase of current in resistance property simultaneously.Therefore, be necessary the leakage current of lightning protection device is monitored, thereby rationally judge the duty of lightning protection device, guarantee the normal operation of lightning protection device.
At present, the structure of the system of existing monitoring leakage electric current in front end current sample and signal transmission is comparatively loaded down with trivial details, so that the link of monitoring is more, the measurement and the record that leak electricity to lightning protection device have brought inconvenience.
The utility model content
The purpose of this utility model is to overcome the weak point of original technology, and a kind of simple in structure, easy to use, with low cost, lightning protection device leakage current measurement system of having saved manpower and material resources is provided.
The technical scheme that the utility model technical solution problem adopts is:
A kind of lightning protection device leakage current measurement system, comprise that lightning protection device, leakage current gather front-end module, leakage data collection and control device, leakage current monitoring backstage, described leakage current gathers an end ground connection of front-end module, its other end is connected with lightning protection device, leakage current gathers front-end module and is connected with an end of described leakage data collection and control device, and the other end of leakage data collection and control device is connected with leakage current monitoring backstage.
And the other end that described leakage current gathers front-end module is connected by the end of optical fiber with described leakage data collection and control device.
Advantage of the present utility model and good effect are:
1, the utility model lightning protection device leakage current measurement system architecture is simple, easy to use, the leakage current that is provided with gathers the sampling that front-end module has been realized leakage current, and isolates resistive leakage current from the leakage current of sampling, and induction is sensitive, accuracy is strong, and reliability is higher; Leakage current gathers front-end module and is connected with leakage data collection and control device by optical fiber, uses Optical Fiber Transmission can effectively avoid the interference of strong electromagnetic, has improved the efficient of transmission.
2, the monitoring of the leakage current in the utility model lightning protection device leakage current measurement system backstage can be realized advanced analysis and the record of data expeditiously, has saved widely manpower and material resources, has reduced cost, can effectively increase work efficiency and work quality.
