Abstract
The utility model discloses a secondary circuit line checker, comprising a casing [1], indication lamps [2], pins [3], a common terminal interface [4] and an expansion interface [5]. In the secondary circuit wiring detection, the common terminal interface [4] is connected with any meter pen when a universal meter is for measuring conduction, the pins [3] are inserted in a terminal row of a to-be-tested circuit, and another branch of the universal meter pen is connected with the other end of the to-be-tested secondary circuit. If the secondary circuit is correct in wiring, the indication lamp [2] corresponding to the number of the terminal row is lighted. If the secondary circuit is wrong in wiring, and a terminal of the tested line is the terminal contacted with one pin of the secondary circuit line checker, the indication lamp [2] corresponding to the wrongly-connected terminal is lighted, and if the indication lamp [2] is not lighted, the position of the terminal row in which the secondary circuit line checker is inserted can be changed until the wrongly-connection position is found out. Thus, the secondary circuit line checker is convenient in secondary loop detection, the efficiency of finding out wrong wiring and checking a line can be improved, and the labor intensity of detectors is lowered.
Description
Technical field
The utility model relates generally to electrical equipment secondary circuit, refers in particular to a kind of secondary circuit core line device, can coordinate the convenient whether correct device of secondary circuit wiring that detects of multimeter.
Background technology
The normal operation of electrical production can be destroyed or affect to the fault of secondary circuit often.For example the secondary circuit wiring of Ruo Mou electric substation differential protection is wrong, when the load of transformer belt is large or during passing through property phase fault, mistrip will occur; When if route protection wiring is wrong, once system breaks down, may make not tripping of this tripping operation of isolating switch, that should not trip has but jumped lock, the major break down that will cause device damage, electric system to disintegrate; If measuring circuit has problem, just will affect metering, few electricity charge of receiving or receiving user more, are also difficult to judge that whether the quality of power supply is qualified simultaneously.Therefore,, though the non-main body of secondary circuit, it,, guaranteeing the safety of electrical production, provides the qualified aspects such as electric energy all to play an important role to user.
But because secondary circuit wiring is more, when construction, inevitably there is the situation of secondary line wrong terminal.If only adopt multimeter to detect, the in the situation that of secondary line wrong terminal, can only a terminal of a terminal go searched; But generally the terminal of this wrong, near its corresponding terminal number, also can spend many time even if search like this position of wrong.The secondary terminals wiring that is exactly in addition current-voltage transformer is far away apart from its wiring cabinet, like this will be at one end by secondary terminals short circuit grounding, whether correctly at the other end, with multimeter, measure its connection terminal, at this moment because shorting stub does not have indicating device, if secondary line wrong terminal now, can only go one by one to measure, will waste like this testing staff's detection time, reduce the work efficiency that secondary circuit detects.
This patent once can only detect single line road, search mis-wired position a kind of secondary circuit core line device of the Design of Problems such as having lost time for secondary detection, can a plurality of secondary terminals of short circuit and have pilot lamp to indicate the loop that will detect, improved the work efficiency that secondary circuit detects.
Summary of the invention
In order to solve the low and remote secondary circuit of secondary circuit mis-wired detection efficiency, once can only check the shortcoming of single line, the utility model is intended to design a kind of secondary circuit core line device, to improve the efficiency of secondary circuit wiring checking work, reduce staff's labour intensity.
The technical solution adopted in the utility model is:
This secondary circuit core line utensil has a plurality of pins, and a plurality of pins one end is connected with capable of bidirectional luminescence diode, and the other end is connected on and is once connected to common port.In secondary circuit wiring detects, any test pencil when the common port interface of this secondary circuit core line device is connect to multimeter measurement conducting, the pin of this secondary circuit core line device is inserted to line terminal row to be checked, the other end of the secondary circuit that another access of pen meter of universal meter will be measured, if secondary circuit wiring does not have mistake, the pilot lamp of corresponding terminal row number is bright; If the terminal that secondary circuit exists wiring error and measuring circuit to connect is the terminal that this secondary circuit core line device pin contacts, the corresponding pilot lamp of the terminal of this misconnection is bright; The terminal that measuring circuit connects if secondary circuit exists wiring error is not any one terminal that this secondary circuit core line device pin contacts, now do not have pilot lamp bright, now can change the insertion terminal row's of secondary circuit core line device institute position, until find position that false wiring connects.
Described a kind of secondary circuit core line device pin, its size is consistent with spacing with secondary circuit terminal row instrument connection size with spacing, facilitates the insertion of secondary circuit core line device.
Described a kind of secondary circuit core line utensil has common port interface and expansion interface.
The pin of described a kind of secondary circuit core line device adopts metallic conduction material, and casing adopts insulating material to make, and it is 4mm standard banana jack that common port interface and expansion interface adopt diameter, to facilitate with multimeter, is connected.
Described a kind of secondary circuit core line device pilot lamp all adopts capable of bidirectional luminescence diode.
Employing the utlity model has following advantage:
1, the pin of secondary circuit core line device and size and the spacing of terminal row instrument connection are consistent, have facilitated the insertion of core line device, also can, according to the terminal row of different model, design the core line device of different profiles for rig-site utilization simultaneously.
2, the expansion interface of the common port interface of a secondary circuit core line device and another secondary circuit core line device is coupled together and just two secondary circuit core line devices can be formed to series relationship, can once search more multiterminal.
3, common port interface is that 4mm standard banana jack is identical with general multimeter jack with expansion interface employing diameter, adopting a two to be diameter is that the wire of 4mm standard banana plug just can couple together multimeter one end and secondary circuit core line device easily, facilitates execute-in-place.
4, core line device pilot lamp adopt capable of bidirectional luminescence diode in use needn't note using in the polarity of pen meter of universal meter, facilitated the application of core line device at the scene.
In sum: secondary circuit core line device can facilitate secondary circuit to detect, and improves the efficiency of searching false wiring and core line, has reduced testing staff's labour intensity.
