Abstract

The utility model provides a novel fault indicator. The novel fault indicator comprises a 430 single-chip microcomputer, a direction board, a cell, a wireless communication module, an electric field/magnetic field induction device and an energy-gaining CT, wherein the energy-gaining CT is connected with the 430 single-chip microcomputer through a current signal and is connected with the cell through power source output, the cell provides power for the 430 single-chip microcomputer, the electric field/magnetic field induction device is connected with the 430 single-chip microcomputer through a voltage signal, the wireless communication module is connected with the 430 single-chip microcomputer, and the 430 single-chip microcomputer is connected with the direction board through a light emitting and board turning signal. Through the novel fault indicator, a line inspector can rapidly determine a fault segment through alarm display of the indicator to find out a fault point, the novel fault indicator has functions of short circuit identification and grounding fault identification, so blind line inspection is avoided, power failure time is shortened, a speed for searching fault points in a power transmission line is improved, work intensity of a power transmission operation maintainer for accident processing is reduced, and power supply reliability is improved.

Description

The novel fault indicator
Technical field
The utility model relates to a kind of fault detector, particularly a kind of novel fault indicator.
Background technology
The most of power distribution networks of China all adopt not solidly grounded system (NUGS) of neutral point, in recent years, along with being extensive use of from the motion tracking arc, resonance problems for the appearance of resolution system instant of failure, begin to adopt arc suppression coil to join with non-linear resistance string (or also) and the method for operation in parallel with lightning arrester, the probability that singlephase earth fault takes place NUGS is the highest, at this moment power supply still can guarantee the symmetry of line voltage, and fault current is less, do not influence the power supply continuously of loading, so needn't trip immediately, rules regulations can continue to move 1~2h, but along with the increasing of feeder line, capacitance current is also increasing, long-play just easily makes fault be expanded into or multipoint earthing short circuit at 2, arc grounding also can cause the total system superpotential, and then damage equipment, destroys system safety operation, so must in time find faulty line to be excised, this be the deficiencies in the prior art parts.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of novel fault indicator, described novel fault indicator is by 430 single-chip microcomputers, direction board, battery, wireless communication module, electric field/magnetic field induction installation and get and can CT form, get and to connect 430 single-chip microcomputers by current signal by CT, connect battery by power supply output, battery is given the power supply of 430 single-chip microcomputers, the electric field/magnetic field induction installation connects 430 single-chip microcomputers by voltage signal, wireless communication module connects 430 single-chip microcomputers, and 430 single-chip microcomputers connect direction board by luminous and board turning signal.
After the novel fault indicator circuit that the utility model provides broke down, the track walker can determine fault section rapidly, and find out the trouble spot to have the function of identification short circuit and earth fault by the alarm indication of indicator.In time reset after permanent fault restored electricity; The time delays of transient fault by user's agreement resetted, stay the enough demonstration time for trouble-shooting hidden danger, stop the malfunction phenomenon that excitation surge current causes, avoid blindly line walking, reduce power off time, improve the seek rate of failure point of power transmission line, alleviated the working strength of transmission operation maintainer accident treatment, improved power supply reliability.
