Abstract
The invention discloses a switching equipment temperature rise detection system, which comprises a multi-path analog switch, an analog/digital (A/D) conversion circuit, a singlechip processing module and a liquid crystal display (LCD) module connected sequentially, and a plurality of thermocouples connected with the multi-path analog switch; and an isolated acquisition circuit is connected between the multi-path analog switch and each thermocouple. The system solves the problems of low switching equipment temperature rise detection efficiency and low measurement precision in the prior art; the temperatures of electrical connection points of switching equipment are acquired through the multi-path thermocouple acquisition circuits, processed through the related processing modules and displayed by the LCD module, so that great convenience is brought to temperature rise detection of the switching equipment before leaving a factory; and the system has stable performance and strong anti-interference capability, and can greatly improve the detection efficiency.
Description
Technical field
The present invention relates to a kind of switchgear temperature rise detection system, belonged to the switchgear technical field.
Background technology
Along with the continuous development of science and technology, society has proposed increasingly high requirement to the reliability of power system device.Switchgear is as one type of wide, the most the most used controller switching equipment of use face, and its quality especially receives publicity.
Switchgear all must advance the temperature rise test before dispatching from the factory, at present, a lot of factories commercial city is to adopt the method that detects manually to accomplish test, and not only inefficiency, and reliability is not high.The temperature rise detection system that production firm adopted that has adopts temperature sensor usually, because volume is bigger, the precision of measurement is not accurate enough.
Summary of the invention
Technical matters to be solved by this invention provides a kind of switchgear temperature rise detection system; Gather the temperature signal that is electrically connected the place in the switchgear through thermopair; Through showing related data after the correlation module processing, this detection system measuring accuracy is high, antijamming capability is strong, can improve detection efficiency greatly.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of switchgear temperature rise detection system; Comprise the multiway analog switch, A/D conversion circuit, single chip processing module, the LCD display module that connect successively; It is characterized in that: also comprise the thermopair that a plurality of and said multiway analog switch is connected, also be connected with one the tunnel between said multiway analog switch and each thermopair and isolate Acquisition Circuit.
Aforesaid switchgear temperature rise detection system is characterized in that: also comprise a host computer that is connected with said single chip processing module.
The invention has the beneficial effects as follows: the present invention gathers the temperature of each electric connecting point of switchgear through the multi-channel thermocouple Acquisition Circuit; And handle through related process module and to show by the LCD display module; The temperature rise that greatly facilitates before switchgear dispatches from the factory detects, and this device performance is stable, antijamming capability is strong, can improve detection efficiency greatly.
Description of drawings
Fig. 1 is that the module of switchgear temperature rise detection system of the present invention connects synoptic diagram.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of switchgear temperature rise detection system; Comprise the multiway analog switch, A/D conversion circuit, single chip processing module, the LCD display module that connect successively; It is characterized in that: also comprise the thermopair that a plurality of and said multiway analog switch is connected, also be connected with one the tunnel between said multiway analog switch and each thermopair and isolate Acquisition Circuit, also comprise a host computer that is connected with said single chip processing module.
Thermopair is embedded in the top layer of testee; The temperature signal that collects is amplified the line linearity processing of going forward side by side through isolating Acquisition Circuit; Through the Single-chip Controlling multiway analog switch; Realize to select different measurement passages, convert the analog quantity that collects into digital quantity through the A/D modular converter and be transferred to single-chip microcomputer and handle, the result that processing is had is through LCD display module and host computer demonstration.When test was accomplished, host computer can be produced the Excel examining report for tester's reference.
In sum; The invention provides a kind of switchgear temperature rise detection system; Gather the temperature signal that is electrically connected the place in the switchgear through thermopair; Through showing related data after the correlation module processing, this detection system measuring accuracy is high, antijamming capability is strong, can improve detection efficiency greatly.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
