Abstract

The utility model relates to a double-cable fault indicator. The double-cable fault indicator comprises a shell and optical fiber communication interfaces; the top of the shell is provided with the optical fiber communication interfaces which are upwards upright; sensors and a circuit board are arranged in the shell; the optical fiber communication interfaces are connected with the sensors through wires; the sensors are connected with the circuit board through wires; two optical fiber communication interfaces and two sensors exist and are in one-to-one correspondence connection with each other; each optical fiber communication interface includes a binding post and conductive sheets; each binding post is mounted vertically on the top of the shell; three cable core jacks are produced on each binding post; and the bottom of each cable core jack is connected with one conductive sheet. According to the double-cable fault indicator of the utility model, a second optical fiber communication interface and a related circuit are additionally arranged on a fault indicator main machine based on an original fault indicator, and therefore, the double-cable fault indicator can detect fault situations of double cables simultaneously, and when a fault occurs on one line, and as long as a fault occurs on one of the two cables, the fault indicator main machine can display fault states or perform warning.

Description

Paired cable fault detector
Technical field
The utility model belongs to distribution checkout equipment field, especially a kind of paired cable fault detector.
Background technology
Line-failure indicator is to be applied on electric line, power cable and switch cubicle line, is used to indicate the device of fault current circulation.Once line failure, track walker can be by the alarm indication of indicator, and the localization of faults rapidly, fixes a breakdown.Thoroughly change blindness line walking in the past, the backward way of segmentation combined floodgate power transmission looking up the fault.Its principle of work be the size of current collecting according to the sensor in line-failure indicator whether overrate judges whether this cable breaks down, and carry out cable work and make state and show, assist maintenance personal to carry out fault handling.
The fault detector of common model can only be arranged on the triple cable of a 10kv at present, but for paired cable and take that (two the head end of cable is overlapped on same contact, tail end rides on same contact) high voltage power distributing cabinet, if only use a set of line-failure indicator, can only carry out fault detect in paired cable, cannot detect the failure condition of another cable; If use two set of fault indicators, although can realize the function that paired cable failure condition detects simultaneously, can cause that to take switch cubicle space excessive, increase complex circuit degree, the problem such as raise the cost.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and is not changing on the basis of Whole Equipment volume, improves the paired cable fault detector of detection efficiency.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of paired cable fault detector, comprise housing and optical communication interface, in case top, optical communication interface is installed straight up, at housing, be built-in with sensor and circuit board, optical communication interface is by wire connecting sensor, sensor is by wire connecting circuit board, described optical communication interface and sensor are two and connect one to one, each light communication interface includes a binding post and conducting strip, each binding post is vertically arranged on case top, on each binding post, be shaped with three cable core jacks and a ground wire jack, each cable core jack bottom connects respectively a conducting strip downwards, each conducting strip is all positioned at housing and is connected with sensor.
And, single-chip microcomputer and control circuit are installed, detection data that single-chip microcomputer transmits by control circuit receiving sensor and send command signal on described circuit board.
And described sensor is photoelectric sensor.
And three conducting strips that install described each binding post bottom are connected on a sensor.
And all a wiring cap is installed in coaxial engagement on described each binding post, this wiring cap middle part is shaped with through hole.
And, on described housing, be arranged at intervals with a plurality of wiring holes.
Advantage of the present utility model and good effect are:
1, the utility model is on the basis of original fault detector, in fault detector main frame (processing and the state of being responsible for signal show), second optical communication interface and interlock circuit thereof have been added, can realize thus a fault detector main frame and connect two cover signal detection sensors simultaneously, thereby detect the function of paired cable failure condition simultaneously, when line failure, as long as have a cable to break down in paired cable, fault detector main frame can show malfunction or alarm.
2, the utility model is compressed to three cable core jacks and a ground wire jack on former cable optic fibre communication interface position and forms 4 hole optical communication interfaces, to save volume.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the utility model is taken the structural representation (broken section) after wiring cap;
Fig. 4 is the vertical view of Fig. 3;
Fig. 5 is that circuit of the present utility model connects block diagram.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of paired cable fault detector, comprise housing 3 and optical communication interface, in case top, optical communication interface is installed straight up, at housing, be built-in with sensor 7 and circuit board 8, optical communication interface is by wire connecting sensor, sensor is by wire connecting circuit board, single-chip microcomputer and control circuit are installed on circuit board, detection data that single-chip microcomputer transmits by control circuit receiving sensor and send command signal, single-chip microcomputer receives the information that signal transducer gathers, information is analyzed, when appearance is abnormal, alert mechanism is sent instruction, for innovative point of the present utility model is more clearly described, so the alarm lamp on housing or other are shown to electrical equipment is omitted.
Innovative point of the present utility model is:
Described optical communication interface and sensor are two and connect one to one, each light communication interface includes a binding post 2 and conducting strip 6, each binding post is vertically arranged on case top, on each binding post, be shaped with three cable core jacks 9 and a ground wire jack (not label), each cable core jack bottom connects respectively a conducting strip downwards, and each conducting strip is all positioned at housing and is connected with sensor.
The sensor is photoelectric sensor.
Three conducting strips that install each binding post bottom are connected on a sensor.
On each binding post, all a wiring cap 1 is installed in coaxial engagement, and this wiring cap middle part is shaped with through hole 4, for penetrating of triple cable, and the cable core of each cable corresponding cable core jack that inserts one by one respectively after penetrating.
