If detect that electricity, magnetic force caused by coil can control normally-closed contact type relay on the coil of normally-closed contact type relay
The contact of device disconnects.
Step S203, if the coil blackout of normally-closed contact type relay, the contact of control normally-closed contact relay is closed
Close.The contact of normally-closed contact type relay normally-closed contact type relay coil not on it is electric when be in closure state,
If the coil blackout of normally-closed contact type relay, the contact of normally-closed contact type relay is changed into closed form from off-state
State.
Further, auxiliary relay can be normally opened contact type relay, or normally-closed contact type relay
Device.Because auxiliary relay is connected with the coil of normally closed relay normally closed relay can be controlled to be remained open before experiment
State, then by control auxiliary relay coil it is upper electricity or power-off control normally closed relay contact disconnect repeatedly-
Closure.
When auxiliary relay is normally opened contact type relay, the control additional relay contacts of the embodiment of the present invention close
The method of conjunction comprises the following steps：
Step S301, detect the whether upper electricity of coil of normally opened contact type relay.The line of normally opened contact type relay
Circle can control disconnection and the closure of the contact of normally opened contact relay, therefore by detecting the line of normally opened contact type relay

Help the contact closure of relay.
Step S402, by controlling additional relay contacts closure to control electricity on the coil of normally closed relay.Aid in relay
The contact closure of device can make the coil of normally closed relay and configuration power supply form current loop, so that the coil of normally closed relay
Upper electricity.
Step S403, disconnected according to electric control normally closed relay contact on the coil of normally closed relay.Normally closed relay
On coil after electricity, producing magnetic force can control the contact of normally closed relay to disconnect.
By control auxiliary relay contact closure normally closed relay coil on electricity so that normally closed relay
The contact of device disconnects.The contact of normally closed relay before the experiments were performed is off, and can be disconnected the contact normal
Close relay and regard normally opened relay as, using existing relay electrical endurance experimental facilities can be repeatedly switched on-disconnect
Experiment, easy to use and cost are low.
Fig. 8 is the flow chart of relay contact control method according to a third embodiment of the present invention.As illustrated, this method
Comprise the following steps：
Step S501, whether detection auxiliary relay is normally-closed contact type relay.Auxiliary relay can be normally closed
Contact types relay or normally opened contact type relay.Normally-closed contact type relay in its coil blackout at
In closure state, normally opened contact type relay is in closure state when electric on its coil.In order to control auxiliary relay
Contact closure so as to control the contact of normally closed relay disconnect, it is necessary to detect auxiliary relay be normally-closed contact type relay or
Person's normally opened contact type relay.
Step S502, if auxiliary relay is normally-closed contact type relay, by controlling normally-closed contact type relay
The coil blackout control normally-closed contact type relay contact closure of device.The contact of normally-closed contact type relay is in normally-closed contact
Disconnected when electric on the coil of type relay, the contact closure in the coil blackout of normally-closed contact type relay.In order that often
The contact closure of closed contact type relay, then control the coil blackout of normally-closed contact relay.Because normally-closed contact relay
Coil be connected with power supply, power supply can be arranged to 24V dc sources, dc source can also be converted to voltage pulse
Signal, when coil receives pulse signal, the contact of control normally-closed contact type relay disconnects, so as to control normally closed relay
The contact closure of device, connect load and form current loop.When pulse signal disappears, control normally-closed contact type relay touches
Point closure, so as to control the contact of normally closed relay to open, current loop disconnects.
Step S503, if auxiliary relay is normally opened contact type relay, control normally opened contact type relay
It is electric on coil so that normally opened contact type relay contact closure.The contact of normally opened contact type relay is in normally opened contact class
Disconnected during the coil blackout of type relay, the contact closure when electric on the coil of normally-closed contact type relay.It is in order that normally opened
The contact closure of contact types relay, then control electricity on the coil of normally opened contact relay.Because normally opened contact relay
Coil is connected with power supply, and power supply can be arranged to 24V dc sources, and dc source can also be converted to voltage pulse letter
Number, when coil is not received by pulse signal, control normally opened contact type relay contact disconnect, so as to control it is normally closed after
The contact closure of electrical equipment, connect load and form current loop.When receiving pulse signal, normally opened contact type relay is controlled
Contact closure, so as to control the contact of normally closed relay to open, current loop disconnect.
