A signal processing unit and a wireless transmission unit connected with the temperature signal acquisition member are arranged in the casing. A receiving unit is used for receiving output signals of the wireless transmission unit and inputting the output signals into a controlling terminal. The device can obtain continuous temperature signals of a splicing member area and can monitor multiple electric distribution equipment in real time for effectively preventing serious accidents caused by the temperature rise of the splicing member.
Description
Technical field:
The utility model relates to a kind of temperature that is used for the on-line monitoring power-supply unit, especially for the on-line monitoring complete equipment of monitoring high-tension distribution equipment plug connector temperature.
Background technology:
No matter all be connected with feeder cable by plug connector for looped network power distribution cabinet or switch cubicle, be plug connector or cable, and its structure is to be coated with insulation course on the outside surface of metallic conductor.When connecting, the conductor part of cable need be extend in the insulation course of plug connector, and the termination of two conductors is closely contacted.Since above-mentioned looped network power distribution cabinet or switch cubicle control be in or high-tension electricity, for this reason, require grafting between cable and the plug connector or connecting portion must reach closely or even hermetic cooperate and could guarantee the consumer safe operation.If there are impurity such as greasy dirt both loose contacts or contact site, can cause the contact place to produce the lighting network and generate heat; In addition, because plug component is installed in the casing, both generate heat because of loose contact, enough spaces that the heat of its generation can not be spread in time or not spread at all, in this case, the temperature of plugging position can constantly rise gradually, and when temperature is elevated to dangerous critical value, at first the problem of Chu Xianing is that the outer insulation course of cable is damaged under the erosion of high temperature, can produce leakage current then, and along with the generation of leakage current can impel the raising of temperature further and destroy insulation course more seriously.The lighter as a result of this vicious cycle can cause the high-tension distribution equipment scaling loss, and weight person can cause high-tension distribution equipment all to burn even set off an explosion.
Yet, contact between plug connector and cable and badly cause by member self and artificial two kinds of reasons.The member self reason is because plug connector and cable all are members with solid shape of making moulding in advance, whether can reach predetermined tightness degree between the two, depend primarily on the product quality of manufacturer, only can not be satisfied with matching requirements with operator's field engineering, but, even there is matching problem in product quality, its gap is also quite small, and the operator is difficult to the naked eye find; And the artificial origin mainly is because construction and installation are improper or unclean, cause both people from contact site impurity such as greasy dirt to be arranged for causing gap or delay, finally all can cause the plug connector position to produce above-mentioned fault, but, human factor is not to be that operator self is intentional, and its operating conditions and environment also are topmost odjective causes.
In the prior art, high pressure ring power distribution cabinet or switch cubicle are mainly adopted off-line monitoring, its monitoring mode has naked eyes method of direct observation and infrared temperature detection method.The naked eyes method of direct observation is to judge by the plug connector position being carried out experience, but because the plug connector of high pressure ring power distribution cabinet or switch cubicle is placed in this housing, and each parts all has relatively large induction current, so, usually under the situation of outage, carry out during observation, and the error of judging is bigger; And measure temperature with the infrared temperature detector, though can carry out under the transmission of electricity state, the temperature of its detection is an instantaneous value, can not obtain continuous monitor signal.
Summary of the invention:
Task of the present utility model provides a kind of high-tension distribution equipment plug connector on-line monitoring complete equipment that utilize Wireless transmission mode to obtain controller switching equipment plug connector continuous temperature signal.
For finishing above-mentioned task, the technical scheme that high-tension distribution equipment plug connector on-line monitoring complete equipment that the utility model proposed adopt comprises: housing and power supply unit, this housing is equipped with outward and is arranged on the high-tension distribution equipment plug connector or near temperature signal collection parts it and be installed in the housing and the signal processing unit and the wireless transmission unit that are connected with these temperature signal collection parts, and is used to receive the output signal of wireless transmission unit and is entered into the interior receiving element of control terminal.
Described temperature signal collection parts constitute by self having the digital temperature sensor that temperature signal is transformed into electric signal function.
Described power supply unit can adopt battery or manifold type self-control power supply, and this self-control power supply has and comprises pickup coil and the amplifier module and the rectifier stack that are electrically connected with the output terminal of this pickup coil.And described amplifier module and rectifier stack are installed in the shield shell.
Described signal processing unit is made of single-chip microcomputer.
The high-tension distribution equipment plug connector on-line monitoring complete equipment that the utility model proposed can obtain the continuous temperature signal in plug connector zone, and human observer utilizes the terminal real-time to monitor many station power distributions equipment, not only reduce operator's labour intensity, and can prevent the serious accident that Yin Wendu raises and taken place effectively; Temperature sensor described in this device and signal processing unit simultaneously, and parts such as wireless transmission unit all adopt existing parts, and constitute by simple operations, so this device manufacture craft is quite simple, cost is relatively low.
