According to relevant data shows: in 2010, an increase of 29% Chinese contactor market. The main reason for this market are: The lOEM industry market demand pull. In 2010 OEM industry growth on the contactor demand up to 33%. Because the real estate market heating up, 2010 construction machinery and the HVAC industry grows very fast, these industries on the low-voltage contactor application growth in more than 50%. L project market recovery has increased demand for low voltage contactor. Operation in 2010 the chemical industry is good, especially coal chemical industry and fine chemical industry grow larger. With the environmental protection requirements increase, the demand for low-voltage contactor products related to environmental protection has also been a big increase in.
Wiring problems about CJ20-63 of AC contactorMon, 10 Nov 2014 10:44:33 GMT
How to access the CJ20-63 AC contactor, can switch on the line do not anyway? 2According to the coil (380V) voltage to a head coil 1 terminals received. A live wire, and then from the other a live wire leads to a line connected to the normally closed contact button switch, a normally closed contact is connected with one end of the push-button switch to another normally open terminal, from this terminal and then leads to a wire connected to the AC contactor normally open contact, button switch normally open contact another head with a wire connected to the AC contactor coil 2 terminal, an AC contactor normally open contact of the other end is connected to the AC contactor coil is OK 2
Connection time controlled AC contactor switch and cj20Mon, 10 Nov 2014 10:44:16 GMT
What you said is used when the control switch control contactor, the contactor control object you want to control, coil that your time switch control contactor on the line, is actually very simple, I give you talk about the general idea of your own to try to link, you want to know the best, you will be the zero line is connected cj20 A1, the phase from the time switch delay break contacts string to A2, but your time control switch is a mechanical general or time relay that, you try it for yourself, all right.
What is the AC contactor, DC contactor and the biggest difference?Mon, 10 Nov 2014 10:44:01 GMT
1 AC contactor in an emergency can substitute DC contactor, pick-up time cannot exceed 2 hours (because the AC coil heat dissipation than DC difference, this is decided by their different structure), really want to use for a long time the best series resistance in AC coil, in turn, but turns in the coil can not substitute for DC AC contactor 2 AC contactor less, DC contactor coil turn number, from the size of the coil can distinguish the condition of too large for the main circuit current (Ie>250A) under the condition of using the double winding coil contactor coil in series 3 DC relay the reactance is large, small current. If the AC adapter is not damaged, when the right time to put. But the coil of AC relay reactance is small, current is big, if connected to DC will damage the coil. 4 AC contactor has the short circuit ring on the core, DC contactor shall be free from the principle of
Maintenance of cjX electromagnetic coil of AC contactorMon, 10 Nov 2014 10:43:41 GMT
The following will introduce is the maintenance of AC contactor electromagnetic coil: 1 check the coil lead wire connection, such as open welding, burning should be repaired in a timely manner. 2 measuring the insulation resistance of the coil. The 3 coil insulation discoloration, aging, coil surface temperature should not exceed 65 degrees C.
