Description
Technical field
The utility model relates to frequency converter test fixture, particularly relates to a kind of frequency converter bringing onto load test fixture.
Background technology
Frequency converter is accomplished in the process of dispatching from the factory in production, need through too much arriving trace routine, the bringing onto load test connecting motor is exactly wherein one, traditional frequency converter bringing onto load test, often test frequency converter and just need again to connect input RST power lead and UVW output line in frequency converter corresponding wiring terminal, efficiency is very low, if and RST power lead and UVW output line connect instead by operating personnel by mistake, damage of product and test macro damage can be caused, cause unnecessary loss, and operating personnel need frequent dismounting, the power supply of reclosing high pressure, there is certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of frequency converter bringing onto load test fixture not needing frequent dismounting RST power lead and UVW output line.
For achieving the above object, the utility model provides following technical scheme:
A kind of frequency converter bringing onto load test fixture, comprise base plate, locating piece, pressing plate, test connection terminal and elevating mechanism, described locating piece is fixed on described base plate, described frequency converter is stuck in described locating piece, described pressing plate is positioned at above locating piece, described elevating mechanism is fixed on above pressing plate, described elevating mechanism side is provided with elevating mechanism installing plate, test thimble is also provided with below described pressing plate, described test thimble is positioned at directly over the connection terminal of the frequency converter being arranged on locating piece, described test thimble and the test connection terminal be fixed on base plate are electrically connected by wire, described test connection terminal is also electrically connected with input power and threephase asynchronous machine.
As further program of the utility model: be also provided with spring compression mechanism between described thimble and pressing plate, the lower end one connecting ejector pin of described spring compression mechanism, upper end is fixedly connected with pressing plate by spring.
As further program of the utility model: described elevating mechanism installing plate is fixedly installed two one slide rails, described pressing plate is through on described two one slide rails.
As further program of the utility model: described test connection terminal comprises the RST power lead terminals connecting power supply and the UVW output line terminals connecting threephase asynchronous machine.
As further program of the utility model: the side that described locating piece is positioned at bottom edge offers a breach, described frequency converter inserts in locating piece from described indentation, there.
The beneficial effects of the utility model are: described frequency converter bringing onto load test fixture, only frequency converter need be inserted in the locating piece on base plate, by elevating mechanism, test thimble is contacted with the connection terminal of frequency converter again, because test thimble is electrically connected with the test connection terminal be fixed on base plate, input power and threephase asynchronous machine and described test connection terminal is fixedly electrically connected, so when proceeding the test of next frequency converter, dismounting RST power lead and UVW output line is not needed yet, can directly test, improve testing efficiency, and there will not be wiring to connect anti-problem, transformer only need be put into locating piece by operating personnel in addition, at operation elevating mechanism, pressing plate is fallen, do not need to contact high-voltage power-line, handling safety.
