Description
Technical field
The utility model belongs to power diagnostic field more particularly to a kind of power electronics fault diagnosis device.
Background technology
In field of power electronics, high voltage isolator is switch member important in power plant and substation's electrical system
Part mainly serves for ensuring the safety of High-Voltage Electrical Appliances and device in service work, plays the role of isolation voltage.High pressure every
It leaves in the operational process of pass, all can generate heat due to electromagnetic action so that own temperature increases, especially when keeping apart
When the contact of pass is bad or the electric current of carrying is more than upper limit value, high voltage isolator all can abnormal heating, so to keep away
Exempt to switch to burn to lead to safety accident, generally require in real time to examine the high voltage isolator being distributed in each equipment
It surveys, to find in time and positioning failure information.But at present often using manual type to each high voltage isolator one by one into
To search failure, this is not only time-consuming and laborious, but also leverages maintenance or the overhaul efficiency of disconnecting switch for row detection, and then
Reduce the safety and stability of power supply.Patent 201520819262.0 discloses a kind of power electronics fault diagnosis thus
Device realizes automatic detection, but it is needed and high voltage isolator is electrically connected, and not only installation is inconvenient but also needs profession electricity
Power personnel are installed.In addition power electronics fault diagnosis device is usually pasted on casting of electronic device, but common viscose
Easily fall, and if using silica gel, silica gel solidification is very slow, needs to install special bracket, can just be withdrawn after silica gel solidification.This
Outside, diagnostor can be caused to be difficult to remove after diagnostor is pasted, this, which causes diagnostor to go wrong, is inconvenient to repair, and is also inconvenient to back
It receives.
Utility model content
The purpose of this utility model is to provide a kind of power electronics fault diagnosis device, the diagnostor of the utility model is not required to
It to be electrically connected with high voltage isolator, and fixed simple and convenient, replacement easy to disassemble.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of power electronics fault diagnosis device, including diagnostor main body and slot；The both sides molding of the slot one side
There is guide groove, another side forms the silica gel area for pasting silica gel and the fast adhesive area for pasting fast viscose glue；Wherein silica gel area is in middle part,
Fast adhesive area is in silica gel area periphery；The diagnostor main body includes plastic casing, and plastic casing both sides evagination is formed and led
The conducting bar of slot cooperation；Microcontroller is installed, microcontroller is electrically connected with infrared temperature sensor, electromagnetic sensing in plastic casing
Device, wireless transmitter.
Further to improve, the fast viscose glue is glue or resin glue.
It is further to improve, it is adhesive with fluorescence labelling on the plastic casing.
It is further to improve, grid ventilation mouth is formed on the plastic casing, humidity sense is installed at grid ventilation mouth
Answer device, humidity sensor electrical connection microcontroller.
Further to improve, the microcontroller is also electrically connected with memory, GPS locator and voice guard.
Description of the drawings：
In order to more clearly illustrate the utility model, below in conjunction with the accompanying drawings using the form of illustrative examples to practical new
Type is further detailed, wherein：
Fig. 1 is the dimensional structure diagram of the utility model；
Fig. 2 is the structure diagram in slot viscose face；
Fig. 3 is the internal structure schematic diagram of diagnostor main body.
Specific embodiment
The present invention is further described in detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of power electronics fault diagnosis device as shown in Figs. 1-3, including diagnostor main body 1 and slot 2；The slot 2

Line transmitter 11 emits alarm signal to console, and voice guard 17 is controlled to alarm.Slot 2 is pasted into conductor during installation
On, it is tentatively pasted by fast viscose glue, so as to save the trouble of mounting and fixing bracket, is then plugged on diagnostor main body slotting
On slot 2, the Fast Installation of diagnostor main body is facilitated to dismantle.Fast viscose glue is 502 glue or resin glue.It is also pasted on plastic casing 6
There is fluorescence labelling 12.It is reminded for dark place.
Grid ventilation mouth 13 is formed on plastic casing 6, humidity sensor 14, humidity sense are installed at grid ventilation mouth 13
Device 14 is answered to be electrically connected microcontroller 8, for detecting the humidity of ambient enviroment.
As described above, the embodiment to the utility model is described in detail, but as long as essentially without disengaging
The characteristics of the utility model and effect can have many variations, this is apparent to one skilled in the art
