Description
Technical field
Change colour the present invention relates to a kind of transformer breather silica gel and detects alarm device.
Background technique
Due to the variation of transformer temperature, so that air can pass in and out transformer (or tap switch) oil storage tank, transformer is exhaled
Haustorium then plays the role of adsorbing the impurity and moisture in air, in order to avoid transformer makes moist, the insulation to guarantee transformer oil is strong
Degree.The main material of respirator is silica gel particle, is provided according to the operational management of substation, and silica gel discoloration is just needed up to 2/3 or more
The maintenance work of replacement silica gel is carried out, to guarantee the filtering moisture and respiration of transformer breather.
Traditional transformer respirator lacks monitoring means, cannot achieve long-range monitoring, fully relies on operations staff preparatory
Its state and discovering device failure and defect are determined in the tour vacuum phase of arrangement, are relied on the sense of responsibility of operation maintenance personnel, are increased fortune
Cost is tieed up, if the discoloration silica gel in respirator can change colour in advance sometimes, and operations staff cannot send out early due to weather
It is existing, oily pollution and equipment fault in transformer are caused, power failure and economic loss are in turn resulted in, therefore, this problem is solved and compels
The eyebrows and eyelashes.
Summary of the invention
The purpose of the present invention is to provide a kind of a kind of structurally reasonable, the excellent transformer breather silica gel changes of working performance
Color detects alarm device.
The technical solution of the invention is as follows:
A kind of transformer breather silica gel discoloration detection alarm device, it is characterised in that: including silica gel tank, track, motor, can compile
Range controller, imaging sensor, wireless communication module and antenna, orbit ring was around silica gel tank one week, and motor is placed on track, motor
Be connected to programmable controller, imaging sensor connect by conducting wire with programmable controller, programmable controller pass through conducting wire and
Wireless communication module connection, wireless communication module are connect with antenna.
The image that programmable controller acquires imaging sensor carry out gray processing, filtering, edge detection, segmentation pre- place
Reason, so as to the extraction of feature.
Imaging sensor handles Tansducer For Color Distiguishing Cmucam, 320*240 using OpenMV2 3Cam M7 intelligent image
Maximum image processing scheme, spot detection/tracking, frame difference motion detection.
Favorable working performance of the present invention.Imaging sensor is driven to breathe in orbit around silica gel tank one week to extract by motor
The image of silica gel in device is handled compared with through programmable controller, respirator silica gel water suction discoloration is judged, in discoloration silica gel
Greater than total amount 2/3 when, sent a warning message by wireless communication module, notice operation maintenance personnel replace silica gel in time.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of transformer breather silica gel discoloration detection alarm device；
Fig. 2 is a kind of work flow diagram of transformer breather silica gel discoloration detection alarm device.
