Description
Technical field
The utility model relates to installation, the maintenance technology field of a cable or electric wire.
Background technology
The work to core before new cabling is installed is that the relay protection specialty is often carried out the important step of 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 protection screen place's work, not only inefficiency, 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.
The utility model content
The technical problems to be solved in the utility model is to provide 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.
Technical solution adopted in the utility model 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; Lead the core instrument is had at least in a test branch road the core instrument with pair and be serially connected with power supply.
The utility model further improves and is: attention device is light emitting diode and/or hummer; The main power supply of using wire intercommunication itself that power supply in the core instrument is preferably, the negative pole of power supply is connected with communication terminal with test; Be serially connected with power switch better 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 secondary two test branch road docking to the core instrument.
Adopt the beneficial effect that technique scheme produces to be: 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 having adopted specific purpose tool targetedly, improved repair quality, shortened the repair time, facilitated 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.

Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, main to the core instrument; 2, secondary to the core instrument; 3, connection; 4, cable core; D1-D2, light emitting diode; HA1-HA2, hummer; SB1, testing power supply switch; E, main to wired intercom electromechanical source in the core instrument; A, main to core instrument test communication terminal; A, secondary to core instrument test communication terminal; B, main test lead to the core instrument; B, secondary test lead to 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; Lead the core instrument is had at least in a test branch road the core instrument with pair and 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, has energy consumption little, 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 core instrument test branch road.When not carrying out core is worked, with power-off, prevent short circuit.
Using method and principle of work:
Earth mat and the standby core of cable at 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 complete 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 having adopted specific purpose tool targetedly, improved repair quality, shortened the repair time, facilitated operating process.
