Abstract
The utility model relates to a fault indicator, in particular to a short circuit and earth fault indicator which comprises a shell, a wire clamping part, a sensing device part, a logical judgment and control circuit board and a rotating display part, wherein the sensing device part is used for measuring the changing conditions of electric fields and magnetic fields in wires, and transmitting signals to the logical judgment and control circuit board; after the logical judgment and control circuit board transmits the signals to the rotating display device part, actuating coils absorb a magnet to drive a rotating body to rotate; and by the matching of the rotating body and the shell, different contents can be displayed to recognize whether to be in a normal state or a fault state, so that the indictor can accurately and fast indicates a branch and a section where a fault point exists, thereby shortening the time for finding the fault point.
Description
Technical field
The utility model relates to a kind of fault detector, especially a kind of short circuit earth-fault indicator.
Background technology
After supply line breaks down, the backward way of taking the branch section to close a floodgate and search fault and blindly seek usually, waste of manpower and time, and because the height of pole line is higher, distance between device and the observer is far away, and for ease of observing, what this device must be done enough greatly just can see clearly.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of short circuit earth-fault indicator, not only can detect short trouble but also can detection of ground faults, be suitable for overhead transmission line, power cable circuit, when line failure, indicate line fault by modes such as luminous, board turnings, avoid blindly line walking.
The utility model is by the following technical solutions: a kind of short circuit earth-fault indicator, form by shell, thread jamming part branch, induction installation part, logic determines and control circuit board, rotary display part, wherein, shell is formed by connecting by two different cylinders of diameter.Described thread jamming part is divided into shell one end, is made up of two line ball springs, and the line ball spring is fixed on the clamping plate of both sides, and opposite side is located on the keeper.
Described induction installation is made up of the inductive coil that has iron core, and this inductive coil is fixed on the clamping plate of both sides.Logic determines and control circuit board are located in the bigger cylinder of diameter.
In the described rotary display part, be set up in the less cylinder of diameter, establish a pit on the support, the pit both sides have a cylindrical hole respectively, also be provided with the actuation coil of ribbon core on the support, the two legs of iron core is distributed in the both sides of magnet by the insertion of the cylindrical hole on the support; The axle of rotary body is to prop up to stay in the housing with pit, is interspersed in the hammer shape thimble of the interior needle-like thimble of rotary body central shaft right cylinder and its top, by the pit and middle interspersed up and down the linking up of screw thread pit of housing on support top.
Further, rotary body has three viewable portions, and the outside of rotary body is with reflective membrane; Housing has three visual windows.By cooperating of rotary body and housing, can distinguish normal condition or break down that vision is strong by the different content that shows, can obviously indicate night.
When line-to-ground or short trouble took place, the inductive coil that has iron core of induction installation part was measured the situation of change in electric field magnetic field in the lead and is carried signal to logic determines and control circuit board.Logic determines and control circuit board receive the signal that induction installation sends, and carry out logic determines, send instruction, partly carry signal to rotating display device.After rotating display device was partly received signal, the actuation coil of ribbon core magnetized, and actuation coil attracts the rotation of magnet driven rotary body, by cooperating of rotary body and housing, can distinguish normal condition or broke down by the different content of demonstration.
The beneficial effects of the utility model are: by induction installation and logic determines and control circuit, accurate, rapid indication fault point place branch of energy and section, shorten the trouble spot and search the time, reduce the loss of power failure area and electricity sales amount, avoid repeatedly dividing, closing a floodgate, prolong the operation life of power equipment.By cooperating of rotary body and housing, can distinguish normal condition or break down that vision is strong by the different content that shows, can obviously indicate night.
