Abstract
The invention relates to a leakage source finding instrument. The leakage source finding instrument comprises an isolation transformer, and is characterized in that the input side of the isolation transformer is connected onto a low-voltage electric power circuit through a service switch; the output side of the isolation transformer is connected with a diode voltage stabilizing circuit through a first change-over switch; the diode voltage stabilizing circuit is connected with a vehicle storage battery; the output side of the isolation transformer is further connected with an ampere meter through a second change-over switch; the ampere meter is connected in series with an output indicating lamp.
Description
Technical field
The invention belongs to detection of electrical leakage technical field, relate to a kind of electric leak detecting device, instrument searched by especially a kind of rain supply.
Background technology
Along with the continuous lifting of living standards of the people, indoor power line curb wall lays the mode of trend and obtains the generally favor of vast power consumer.Although circuit laying scheme within the walls is attractive in appearance, but owing to the reasons such as the quality of housing construction (are such as leaked, rural area is excellent is universal), when the faults such as line electrical leakage occur, trouble shoot is brought bigger difficulty, the dependent failure equipment sold on market is primarily directed to enterprises and institutions' power consumer, because using the reasons such as cost height, equipment technical parameters do not mate with residential customers, so residential customers can not be served.
Find by inquiry: in most of urban residents families, the operation present situation of power circuit is: through the concentrated gas meter box outlet of power department, lay along wall face and register one's residence through wall body hole, indoor main line lays on each room ceiling, and each room branch line is slotted poling along metope, lays for hidden in pipe；Most of indoor it is not provided with branch aftercurrent action protecting equipment and chopper.Prior art is all by selective examination or the custom formula troubleshooting method of generaI investigation line facility, time-consuming the most laborious.In place of this is the deficiencies in the prior art.
Therefore, for drawbacks described above of the prior art, it is provided that instrument searched by a kind of rain supply of design, to solve above-mentioned technical problem, is necessary.
Summary of the invention
It is an object of the invention to, the defect existed for above-mentioned prior art, it is provided that a kind of rain supply of design searches instrument, to solve above-mentioned technical problem.
For achieving the above object, the present invention provides techniques below scheme:
Instrument searched by a kind of rain supply, including isolating transformer, it is characterized in that: the input side of described isolating transformer is connected to low-voltage power line by service switch, the outlet side of described isolating transformer has diode mu balanced circuit, described diode mu balanced circuit to connect vehicle accumulator by the first switching switch connection；
The outlet side of described isolating transformer connects ammeter also by the second switching switch, and ammeter is in series with output indicator.
The beneficial effects of the present invention is, make full use of isolating transformer, it is concatenated in client's house lead in circuit, earth current is isolated, disconnects all electric equipments, circuit is carried out charging operation, the branched line in client family need not be released, with the use of suitable range ammeter, quickly, accurately find leakage point of electricity, it is achieved target quick, accurately lookup leakage point of electricity；It is greatly saved human and material resources.Additionally, design principle of the present invention is reliable, simple in construction, there is application prospect widely.
As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and improves significantly, and its beneficial effect implemented also is apparent from.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams that instrument searched by a kind of rain supply that the present invention provides.
Wherein, 1-isolating transformer, 2-service switch, 3-low-voltage power line, 4-first switches switch, 5-diode mu balanced circuit, 6-vehicle accumulator, and 7-second switches switch, 8-ammeter, 9-output indicator.
Detailed description of the invention
The present invention will be described in detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are explanation of the invention, and the invention is not limited in implementation below.
As shown in Figure 1, instrument searched by a kind of rain supply that the present invention provides, including isolating transformer 1, the input side of described isolating transformer 1 is connected to low-voltage power line 3 by service switch 2, the outlet side of described isolating transformer 1 has diode mu balanced circuit 5, described diode mu balanced circuit 5 to connect vehicle accumulator 6 by the first switching switch 4 connection；
The outlet side of described isolating transformer 1 is also by the second switching switch 7 connection ammeter 8, and ammeter 8 is in series with output indicator 9.
During use, ammeter is connected to circuit to be detected, leakage current can have been detected whether.
Only the preferred embodiment of the present invention disclosed above; but the present invention is not limited to this; what any those skilled in the art can think does not has creative change, and the some improvements and modifications made without departing from the principles of the present invention, all should be within the scope of the present invention.
