Abstract
The utility model provides an ideal wireless alarm device for giving alarms on power transformer outgoing line connecting point heating, which belongs to the technical field of power equipment maintenance. The device is characterized in that a transmitting part and a receiving part are provided; the transmitting part is provided with a liquid crystal display screen on which a camera is installed; and the receiving part is provided with a liquid crystal display screen. When there is heating or other abnormal situations happening to a power transformer outgoing line connecting point, a corresponding video circuit can be started in time to send video signals back, and monitoring staff can inform maintainers of more detailed and accurate fault status according to video display, which brings convenience to the daily work of maintenance and rush repair personnel, improves the work efficiency of equipment maintenance and rush repair, and enhances power supply reliability of power equipment. Compared with the prior art, the device has the obvious advantages of easy and quick maintenance.
Description
Technical field
The utility model belongs to power equipment maintenance technology field, is specifically related to a kind of power transformer outlet tie point heating radio alarming dress.
Background technology
Existing power transformer outlet tie point heating wireless alarmer can only send to the plant maintenance personnel " the unusual alarm signal of generating heat " when the abnormal conditions of heating appear in tie point.Do not knowing in the situation of field conditions, the maintainer rushes towards fault in-situ inspection, analyzes and processes, sometimes the maintainer can delay less because not knowing site specific the process of maintenance with some professional service kit, bears the character of much blindness to scene of the accident band.Therefore prior art exists: check difficulty, maintenance speed waits not enough slowly.
The utility model content
The purpose of this utility model be design provide a kind of inspections accurately, the fireballing a kind of power transformer outlet tie point of the maintenance wireless alarmer that generates heat.
For reaching above-mentioned purpose, the main technical schemes that the utility model is taked is, this power transformer outlet tie point heating radio alarming dress, has radiating portion, receiving unit, it is characterized in that: described radiating portion comprises: temperature element, relay, LCDs, button, single-chip microcomputer, video-unit, camera, transmitter module, temperature element connects single-chip microcomputer, relay connects single-chip microcomputer, LCDs connects single-chip microcomputer, button connects single-chip microcomputer, and module is penetrated in the single-chip microcomputer sending and receiving, and camera is contained on the video-unit; Receiving unit comprises: LCDs, receiver module, alarm module, and receiver module connects LCDs, and alarm module connects receiver module.
The utility model provides a kind of desirable power transformer outlet tie point heating wireless alarmer for power equipment maintenance technology field.Its principal feature is: be provided with emission, receiving unit, radiating portion is provided with the LCDs that camera is housed, receiving unit is provided with LCDs, when the heating of power transformer outlet tie point, abnormal conditions, can in time start corresponding video circuit and pass vision signal back, the monitor staff can according to video display notification maintainer more in detail, failure condition accurately, made things convenient for maintenance, repair personnel's routine work, be conducive to improve the work efficiency of plant maintenance, repairing, be conducive to improve the power supply reliability of power equipment.Compare in prior art: have maintenance conveniently, maintenance speed waits remarkable advantage soon.
Description of drawings
Reach by reference to the accompanying drawings example and further specify specific structural features of the present utility model.
Fig. 1 is the circuit block diagram of radiating portion of the present utility model.
Fig. 2 is the circuit block diagram of receiving unit of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises: radiating portion, receiving portion; Described radiating portion comprises: temperature element 1, relay 2, LCDs 3, button 4, single-chip microcomputer 5, video-unit 6, camera 7, transmitter module 8, temperature element 1 connects single-chip microcomputer 5, relay 2 connects single-chip microcomputer 5, LCDs 3 connects single-chip microcomputer 5, button 4 connects single-chip microcomputer 5, module 8 is penetrated in single-chip microcomputer 5 sending and receiving, camera 7 is contained on the video-unit 6: described receiving unit comprises: LCDs 9, receiver module 10, alarm module 11, receiver module 10 connects LCDs 9, and alarm module 11 connects receiver module 10.
Principle of work is introduced: temperature element is installed in the tie point place that needs detection, is close to tie point metal part in order to effectively lead temperature, generally should be installed in the first of transformer, female disconnecting link contact place.Camera is installed in the point for measuring temperature next door, alignment lens point for measuring temperature position, and bushing bottom or the female disconnecting link of transformer that generally will be installed in transformer are supported the porcelain vase bottom.Set in advance the permission operation higher limit of thermometric by the button of single-chip microcomputer, when thermometric numerical value surpasses setting value, single-chip microcomputer signal output starting relay J, its normally opened contact J2 is communicated with the video-unit power supply, video circuit is started working and is carried out the video monitoring, the simultaneously closed startup of normally opened contact J1 transmitter module circuit work power, the such temperature of point for measuring temperature, vision signal all can outwards be launched by the transmitter module circuit, the monitor staff can be more detailed according to video display notification maintainer, failure condition accurately, made things convenient for maintenance, repair personnel's routine work, be conducive to improve plant maintenance, the work efficiency of repairing is conducive to improve the power supply reliability of power equipment.For safety the working power of device can be selected 12 ~ 24V DC power supply.
Occur just starting transmitter module after the situation of heating when tie point, the video circuit purpose is saves energy, can also reduce the circuit component working time, extension fixture serviceable life.
