Brief description of the drawings
Fig. 1 is the electric elements schematic layout pattern of the utility model embodiment；
Fig. 2 is the circuit theory diagrams of the utility model embodiment.
Embodiment
The utility model is described in detail below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of device for checking electric relay, all electric elements include power module, relay base, slip electricity
Resistance, megameter, low ohmmeter, voltmeter, switching handle, terminal block and 10A are spaced apart, and are installed on an installation base plate, power supply
AC220V is converted to DC24V and provides power supply for relay by module；The quantity of low ohmmeter is 2, is connected on relay difference respectively
On contact, the contact resistance of measuring relay open and close contact；The quantity for switching handle is 2, switches handle QK1 by changing,
Measuring relay coil resistance starts voltage；Switch handle QK2 by changing, the contact electricity of measuring relay open and close contact
Resistance；Relay startup voltage and return voltage are verified by adjusting slide wire resistance；Voltage, electricity are measured by voltmeter, ohmmeter
Resistance.
Referring to Fig. 2, when verifying relay, first relay is inserted on relay base, switching handle QK1 is switched to resistance
Shelves, switching handle QK2 are switched to normally closed contact shelves, and megameter registration is exactly relay-coil resistance, and low ohmmeter registration is exactly normally closed
The contact resistance of contact；Slide wire resistance is transferred to maximum resistance, switching handle QK1 is switched to voltage gear, switching handle QK2 is cut
To normal opened contact shelves, close a switch F1（10A is spaced apart）, voltmeter registration is exactly relay both end voltage, adjustment slide wire resistance order
Voltage during relay excitation is exactly the startup voltage of relay, and now, low ohmmeter registration is exactly relay normally open contact closure
When contact resistance；Adjustment slide wire resistance makes the return voltage that voltage during relay loss of excitation is exactly relay.
It should be noted item：Relay must be inserted on relay base by switching handle QK1 before being switched to voltage gear；Verification
F1 must will be switched after a complete relay（10A is spaced apart）Pull open or slide wire resistance is turned up full blast resistance value.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is done any type of
Limitation, any content without departing from technical solutions of the utility model, according to the technical essence of the utility model to above example
Any simple modification, equivalent change and modification done, belong to the scope of technical solutions of the utility model.
