Q:Time control switch for a shortest time to add time relay to reduce the time to a few seconds how to increase
Plus a ST3P power delay time relay, the time relay coil and relay two groups of public point connection, often close to you want to control the equipment such as bell, the control switch output power supply relay coil, so you can
Q:What is the difference between the total switching time and the excessive time in the transformer on-load tap-changer test data?
The total number of a few, that also called what the same period! There are ah! I tell you ha! The nature of the on-load tap-changer and the circuit breaker is almost a switch itself, but there is an over-resistance or an over-device in the same period, the same period refers to the synchronization between the three phases, three different numbers Normal, the key is whether the deviation in line with national norms or industry standards.
Q:Refrigerator outside the regulator how to adjust the shutdown time in summer
Refrigerator using external temperature control is generally adjusted to start 20 minutes, stop 40 minutes for the best, but also according to the actual situation of refrigeration may be, if the cooling is not ideal, it is recommended to increase the start of the appropriate time to not exceed the time As a reference value.
