Abstract
The utility model discloses a general signal acquisition wire used for an SF6 density relay calibrating device, and solves the problem that the connection between a signal acquisition wire in the prior art and an electrical contact of a density relay calibrating device is unstable. The general signal acquisition wire used for the SF6 density relay calibrating device comprises a signal bus (1). Eight sets of signal acquisition wires are arranged in the signal bus. Each set of signal acquisition wires is composed of a first signal acquisition wire (2), a second signal acquisition wire (3), and a third signal acquisition wire (4). An end portion of the first signal acquisition wire is connected with a U-shaped signal acquisition wire joint (5). An end portion of the second signal acquisition wire is connected with a pan-cap type signal acquisition wire joint (6). An end portion of the third signal acquisition wire is connected with an alligator-clip-type signal acquisition wire joint (7). The general signal acquisition wire used for the SF6 density relay calibrating device of the utility model reduces the wiring workload in regular calibrating of an SF6 density relay, improves the signal acquisition quality, and prolongs the usage life of the signal acquisition wire.
Description
Technical field
The utility model relates to a kind of signals collecting line, and is particularly a kind of to SF
6When density monitor carries out verification at SF
6The signals collecting line that is connected between density monitor and the tester.
Background technology
In electric system, according to the requirement of safe operation, need carry out periodic check to the SF6 density monitor, avoid the density monitor misoperation or the phenomenon of misdirection occurs, thus the various factors of the power network safety operation of eliminating the effects of the act.When the SF6 density monitor is carried out periodic check, need to gather many activation signals of density monitor electric contact, the signals collecting line of existing detecting instrument generally is to utilize the crocodile clip that has insulating coating to be connected with each electric contact, though crocodile clip has various forms of, as pin type, butterfly, the outlet formula etc., but when it is connected with electric contact, need the careful position of adjusting crocodile clip, to guarantee that it the virtual connection phenomenon do not occur, and the gap between the electric contact of density monitor is less, when using crocodile clip, there is the problem of clamping connection difficulty, in addition, because the solder joint of signal wire and crocodile clip junction is firm inadequately, inappropriate pulling out connects action during operation, causes the contact of crocodile clip and signal wire to disconnect especially easily, had influence on carrying out of whole test job.
Summary of the invention
The universal signal that the utility model provides a kind of SF6 density monitor tester to use is gathered line, and the signals collecting line that has solved existing signals collecting line existence is connected illusive problem with the electric contact of density monitor.
The utility model is to solve above technical matters by the following technical programs;
The universal signal that a kind of SF6 density monitor tester is used is gathered line, comprise signal bus, eight groups of signals collecting lines are set in bus, every group of signals collecting line is made up of the first signals collecting line, secondary signal collection line and the 3rd signals collecting line, be connected with the wire terminal of ∪ shape signals collecting in the end of the first signals collecting line, the end of gathering line in secondary signal is connected with the wire terminal of pen cap type signals collecting, and the end of gathering line in the 3rd wire size is connected with the wire terminal of crocodile clip formula signals collecting.
The end of the first signals collecting line is that the copper of gathering the band U-shaped mouth on the line signal wire joint with ∪ shape is electrically connected in flakes, is provided with insulating sheath in copper upper end in flakes.The end that secondary signal is gathered line be with the pen cap type signal wire joint on the copper sheathing ring be electrically connected, the lateral surface of copper sheathing ring is provided with the hexagon insulation crust.
The utility model can reduce the wiring workload when the SF6 density monitor is carried out periodic check, has improved the quality of signals collecting, has prolonged the serviceable life of signals collecting line.
