1-laboratory work. Experimental analysis with Electromagnet relays

RT - 40 type vine of relays technical indicators
Relays vine according to settings from 0.05 A to 200 A There are 9 types in progress is prepared . Relays Back to coefficients the first from 0.85 in installation the rest in installations and from 0.8 small which cannot be by doing will be done .
Do not install relatively of the relay work so that error from +5 big not _ Relay connector of contacts connection time vine of the relay work 1.2 times from current big from 0.1 s when and 3 times big from 0.03 s when big not _
Relay consumption who does power his fulfillment type depend _ For example the most big setting from 0.05 to 2 A has been relays for installation to 0.2 VA at current equal to
Relays one connector and one interruptible to contacts have _
Relay contacts immutable vine in chains power 60 W up to has been and time constant from 0.005s big didn't happen inductive load , variable vine in the chain while current up to 2A and strength coefficient from 0.5 big from 24V to 250V when at voltages up to 300 VA powerful download disconnection can _
RN-50 type tension of relays technical indicators .
Installations from 15V to 300V There are 3 types in execution is prepared .
Do not install relatively work of voltage the error is up to +10% .
Back to coefficient from 0.8 small not _
Connector of contact connection time relay given tension his work 1.2 times the voltage big from 0.1s when and 2 times big from 0.03 s when big not _
Relay consumption who does power to a minimum setting equal to from 1VA in voltage big not _
WORK PROCEDURE

1. 
   Current relay to try for relay shown in Fig. 1 on the stand scheme collect _
   

Current of the relay from 30A per circuit more than vine to be given if from 36 and 37 sleeves benefit need _

2. 
   Current of the relay spring consecutively connect
   
3. 
   Relay on the scale each installation (charter) up to 1 _place for vine little by little increasing of the relay to work drop off until Big and relay from working after vine slowly reducing of the relay Back to until I _rk the define _ Received the results in Table
