The domestic mature product model CJ20 JNSFC1 NSFC2NSFC3NSFC4NSFC5NSFC12NSFC19CJ40JNSFMR is installed on the contactor linkage mechanism with a permanent magnet with fixed polarity and interacts with the variable polarity soft magnet cured on the contactor base, thereby achieving the purpose of attracting, retaining and releasing. The variable polarity of the soft magnet is generated for more than ten to twenty milliseconds through the electronic module cured with it.

From the perspective of operating mechanism, contactors are subdivided into electromagnetic and permanent magnet types. Among them, permanent magnet AC contactors are an innovative design. They use the principle of same-sex repulsion of magnetic poles to replace the traditional electromagnet drive mechanism with a permanent magnet drive mechanism to achieve micro power consumption. The purpose of control is domestic mature product models include the working principle of CJ20JNSFC 1NSFC2NSFC3NSFC4NSFC5NSFC12NSFC19 CJ40 JNSFMR contactors.

The working principle of the contactor is that when the contactor coil is electrified, the coil current will generate a magnetic field. The generated magnetic field will cause the stationary iron core to generate electromagnetic attraction to attract the moving iron core, and drive the AC contactor to act. The normally closed contact is opened and the normally open contact is closed. The two are linked. When the coil is cut off, the electromagnetic attraction disappears. The armature is released under the action of the release spring, making the contact recover, the normally open contact is disconnected, and the normally closed contact is closed. The working principle of DC contactor follows the temperature.

Common specifications of steel-framed light roof panels include large roof panels, grid panels and gutter panels. Among them, the large-span roof panels are code-named GWB. The core material thickness is usually 100mm, the plate length is 4480mm to 7480mm, and the width is 1180 to 2380 mm. The main ribs can be adjusted according to specific needs to use cold-formed thin-walled C-section steel C160×70×20×30, the end ribs are cold-formed thin-walled C-section steel C100×50×20×25, and the plate surface is made of lightweight composite core.

The structure of the 2JR20 thermal relay adopts a three-dimensional arrangement, also known as the "two-layer" structure, with a tension spring type jumping action mechanism, and the series of action mechanisms are universal. The action indicator can clearly show whether the thermal relay is in action or not, fully considering19cj20The phase-to-phase distance, wiring height and overall size of each current level of the CJ20 AC contactor are described. Therefore, it can be easily installed on the CJ20. It is suitable for the rated insulation voltage of the main circuit from 50Hz to the current of 660V to 01A.

The catalog of 19CJ 2019 CG12 Steel Frame Light Plate Atlas mainly includes the following general board selection table, including the selection table of various specifications and models of steel frame light plate general board. The selection table of large roof panels is divided into one and two parts. It lists the selection information of large roof panels in detail. Grid board selection table provides selection information of grid boards and gutter boards template drawings and connection structures General roof board Large roof board grid boards.

1. In 2012, and in recent years, engineering application feedback has been systematically sorted out and revised, adding trestle floors, evacuation platforms, floors and other contents to meet market demand.

2. The working principle of the contactor is that when the contactor coil is electrified, the coil current will generate a magnetic field. The generated magnetic field will cause the stationary iron core to generate electromagnetic attraction to attract the moving iron core, thereby driving the AC contactor to move. The normally closed contact opens and the normally open contact closes. The two are linked. When the coil is cut off, the electromagnetic attraction disappears, the armature is released under the action of the release spring, making the contact recover, the normally open contact opens, and the normally closed contact closes. The working principle of DC contactor is a little bit.

3. The difference series between CZT1 and CZ20 type contactors is different. One is large and the other is small. Both are a pair of normally coming and a pair of normally closed contactors are divided into AC contactor voltage AC and DC contactor voltage DC. It is used in power distribution and electrical contactors broadly refer to the use of current flowing through coils to generate magnetic fields in industrial electricity to close the contacts to control the load. The working principle of electrical contactors is that they act as contactor coils.

4. 1 The following figure shows the wiring diagram of the AC contactor button. 2 The wiring diagram of the AC contactor button. 21 When starting, the start button is pressed, and the control current from the power supply passes through the circuit breaker power line stop button self-locking line start button starting line coil A2 to coil A1. The contactor coil is electrically attracted, and the main contact is connected to the load, assisting the normally open point to close and self-retaining and self-locking. At this time, the start button is released. Due to the aid of the contactor.

5. The domestic mature product model CJ20JNSFC1NSFC2NSFC3NSFC4NSFC5NSFC12NSFC19CJ40JNSFMR#160 permanent magnet contactor Songfeng is installed on the contactor linkage mechanism with a permanent magnet with fixed polarity and interacts with the variable polarity soft magnet solidified on the contactor base, thereby achieving the purpose of attracting, retaining and releasing. The variable polarity of the soft magnet is through the electrons solidified with it.
