The talkback type cable core instrument comprises a main core instrument and an auxiliary core instrument, the main core instrument and the auxiliary core instrument are both provided with casings, wired intercoms and testing branches, one ends of the testing branches are used as communication ends for testing, the other ends of the testing branches are used as testing ends, a warning indicator is connected in the testing branches in series, and a power supply is connected in at least one testing branch of the main core instrument and the auxiliary core instrument in series. The talkback type cable core instrument has the advantage of being simple in structure, convenient and rapid to use, high in working efficiency, convenient and fast to carry, safe and reliable in core in a protective chamber and the like.
Description
Technical field
The present invention relates to installation, the maintenance technology field of a cable or electric wire.
Background technology
The work to core before new cabling installed is the important step that the relay protection specialty is often carried out the work such as overhaul, in the past at the outdoor terminal box place to core, on one side need two people use intercom or mobile phone communication, Yi Bian use multimeter to cooperatively interact to core; And if indoor to core in protection because the protection chamber bans use of radio communication, need a people in the outdoor contact and passing on a message of making a phone call, a people is in the work of protection screen place, not only inefficiency has additionally taken manpower, and easily the situation to the core mistake occurs.If new cabling quantity is larger, and is longer to the core working time, seriously delayed the duration, and in case to the core mistake, will bring very large impact to follow-up work.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of intercommunication cable core connection testing instrument, belongs to the specific purpose tool of cable core connection testing, and it has simple in structure, convenient to use, high efficiency, it is convenient to carry, indoor to characteristics such as core are safe and reliable in protection.
The technical solution used in the present invention is: comprise main to core instrument and secondary to the core instrument; Main all have shell, wire intercommunication and test branch road to core instrument and pair to the core instrument, and it is test lead that an end of test branch road is used communication terminal, the other end for test, is serially connected with attention device in the test branch road; Main to the core instrument and secondary the core instrument is had at least in the test branch road be serially connected with power supply.
The present invention further improves and is: attention device is light emitting diode and/or hummer; The master is preferably the power supply of using wire intercommunication itself to the power supply in the core instrument, and the negative pole of power supply is connected with communication terminal with test; It is better to be serially connected with power switch in being provided with the test branch road of power supply.
Power supply in the test branch road also can set up.Main to forming current return after core instrument and the secondary two test branch road docking to the core instrument.
The beneficial effect that adopts technique scheme to produce is: conversation to the core instrument integrated to core and wired communication functions, use the loaded down with trivial details of intercom, phone when having save core, avoided the interference of wireless telecommunications to secondary device.Owing to adopted targetedly specific purpose tool, improved repair quality, shortened the repair time, made things convenient for operating process.Have simple in structure, convenient to use, high efficiency, carry convenient, indoor to characteristics such as core are safe and reliable in protection.A kind of very practical in the core instrument.

Embodiment
By embodiment shown in Figure 1 as can be known: comprise main to core instrument and secondary to the core instrument; Main all have shell, wire intercommunication and test branch road to core instrument and pair to the core instrument, one end of test branch road is the test communication terminal, two test communication terminals are two communication terminals that the intercom order circuit is corresponding, and the other end is test lead, are serially connected with attention device in the test branch road; Main to the core instrument and secondary the core instrument is had at least in the test branch road be serially connected with power supply.Conversation to the core instrument integrated to core and wired communication functions, the connection that is connected with communication terminal by main test branch road, secondary test branch road, power supply, two ends and test simultaneously, cable core to be tested consist of the core test loop.
Attention device is composed in parallel by light emitting diode and hummer.The advantages such as light emitting diode belongs to cold light source, and it is little to have energy consumption, and brightness is large, color is various, the life-span is long, it is little that hummer has energy consumption, the advantages such as sound is melodious, long service life.
Power supply is main power supply to the wire intercommunication in the core instrument itself, and the negative pole of power supply is connected with communication terminal with test.Wire intercommunication wherein has a connection to be connected with power cathode, according to these characteristics, can utilize the power supply of intercom itself as the test loop power supply, and it is simplified the structure, and saves cost.
Main to being serially connected with the testing power supply switch in the core instrument test branch road.When not carrying out core worked, with power-off, prevent short circuit.
Using method and principle of work:
Earth mat and cable core for subsequent use at the cable two ends by easy differentiation connect wire intercommunication, can carry out call function, with the testing power supply switch opens, can carry out core work, when to core correct (being the same cable core), what connection, the cable core to be tested that is connected with communication terminal by main test branch road, secondary test branch road, power supply, two ends and test consisted of forms path to the core test loop, major and minor to the hummer above the core instrument and light emitting diode get final product sound and light alarm, prompting is correct to core, that tests is the same cable core.Repeat this process and finish the checking of all cores, can be at any time when carrying out the core operation call function by intercom connect each other, co-ordination, convenient and swift.
Conversation to the core instrument integrated to core and wired communication functions, save and used the loaded down with trivial details of intercom, phone, avoided the interference of wireless telecommunications to secondary device.Owing to adopted targetedly specific purpose tool, improved repair quality, shortened the repair time, made things convenient for operating process.
