Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
The utility model provides a kind of integral type current-voltage transformer on-spot tester, including：Babinet 1 and case lid 2,
Babinet 1 is hinged with case lid 2.
Babinet 1 includes case ontology 11, renovates 12, drawer 13, test subject 14, lock 15.
11 1 right end of case ontology, which is recessed inwardly, is formed with the first groove 111, a lockhole 112, and test subject 14 is embedded in case
Ontology 11, and 14 terminals of test subject extend in the first groove 111；Case ontology 11 is additionally provided with and 14 wiring of test subject
The one-to-one mark in end.
It renovates 12 opposite first groove 111 opening settings and its lower end and case ontology 11 is hinged, and can be covered by rotation
First groove 111.
Drawer 13 is arranged in 11 lower part of case ontology.
Test subject 14 includes detection unit, keyboard, display screen, and detection unit is embedded in case ontology 11, and keyboard is set to
11 open end upper surface of case ontology and be electrically connected with detection unit, display screen be set on 2 inner wall of case lid and with detection unit electricity
Connection.
Lockhole 112 matches with lock 15, and lock 15 includes spring 151, push button 152, fixture block 153, spring 151, push button
152, fixture block 153 is set in turn in from left to right in lockhole 112, and push button 152 is connected with 153 left end of fixture block, and spring 151 is used for
It pushes push button 152 and fixture block 153 along 112 guiding movement of lockhole, and 153 right end of fixture block can be made to be inserted into the card slot for renovating 12 upper ends
It is interior.
Specific workflow first pushes 152 compressed spring 151 of push button, so that fixture block 153 is shunk in lockhole 112, then beats
It opens and renovates 12, take out the connecting line in drawer 13, using connecting line by tested mutual inductor and the corresponding wiring in the first groove 111
Terminal is electrically connected, and power supply is electrically connected with respective terminal in the first groove 111, is tested mutual inductor through connecting line, terminals
Son is electrically connected with detection unit, is opened case lid 2 and is powered on to integral type current-voltage transformer on-spot tester, control box ontology
Control device in 11 tests tested mutual inductor, first closes power supply after the completion of test, then take out stitches.
Detection unit includes that ARM, control circuit, pressure regulator, current lifting device and AD samplers are constituted, ARM and control circuit electricity
Connection, control circuit are electrically connected with pressure regulator and current lifting device respectively, and pressure regulator is electrically connected with current lifting device, AD samplers one end, are risen
Stream device is electrically connected with AD samplers, and the other end of AD samplers is electrically connected with ARM, and display screen, keyboard are electrically connected with ARM respectively.
