LK4Series master controller

1. use

1, LK4series Master controller Applicable to communication 50HZ Voltage to 380Volt and DC voltage to 220The master controller can be connected directly or via a gear unit to the operating mechanism and the master controller contacts are closed or disconnected in a certain order depending on the travel or rotation of the operating mechanism. (Also by auxiliary motor to drive).
1. 1, The master controller of the basic components of a cam assembly and contact assembly.Cam assembly by the combination of the shaft and the wheel.Cam disc from the same two semi-circular blocks formed on each block has ten holes and a circle Slot, two holes interval 18 °The cam plate is provided with a slot which can be moved to the right and left of the fixing bolt 10 ° 30 ', So by the cam control of the contact opening and closing position can also be adjusted due to the master controller contact breaking ability and part of the anti-wear mechanism of the restrictions, the cam disk rotation speed shall not exceed 60turn /Minute.
1. 2. Each cam disc acts as a circuit, and the number of cam discs corresponds to the number of circuits of the controller.When the master controller has more circuits, there are two groups of cams, The cam assembly of the master controller can be rotated in parallel, that is, the two sets of cams can rotate at the same time or in series, that is, the first set of cam assemblies and the second set of cam assemblies turn in turn.
1. 3Press LK4Series master controller shell device can be divided into
1. 3. 1Protected master controller LK4-0LK-1
1. 3. 2Waterproof master controller LK4-6
1. 4Press LK4series Master controller Whether the deceleration can be divided into two types:
1. 4. 1. LK4-024LK4-044LK4-055Is the master controller without deceleration.
1. 4. 2In addition to 1.4.1Listed LK4Master controller ,other LK4The master controller is equipped with a gear unit.
1. 5. LK4-148 / 3LK4-148 / 4LK4-168 / 3LK4-168 / 4LK4-188 / 4The master controller has two sets of cam assemblies, which are connected to the operating mechanism via the gear unit. The deceleration can cause the two sets of cam assemblies to rotate in parallel or in series.
1. 6. LK4-658Type master controller is a waterproof type with a set of cam assemblies that are connected to the drive shaft by a worm gear reducer mounted on the master controller housing The contact series of the master controller is slightly different from the other main Make the controller, its 5In the circuit 2The circuit can be equipped with arc extinguishing device, so the top of the static contact sleeve to the arc cover, the magnetic field generated by the arc coil to produce magnetic blow to achieve the role of arc suppression.

2. Technical data
2. 1Master controller model, the number of circuits, placement, reduction ratio see table 1, Table2

1. 2.3 Master controller Of the operating frequency 1200turn /hour ,but 1The number of minutes connected to no more than 60Times.
2.4 Press the master controller 1200turn /hour ,Communication can afford 20Million times connected and 20Million times breaking ,DC can withstand 10Million times connected 10Million times breaking .(Where the turn-on time 0.2~0.5second ).After the test, the master controller can continue to work.
2.5 Master controller in the absence of current through ,Can afford 100Million times closed and disconnected ,The contact and spring can withstand 30Million times closed off .After the test can continue to use.

2. Principle of action
3. 1Contact disconnected, shaft 1& Lt; / RTI & gt; 3Clockwise rotation.
3. 2Closed cam 2Move to roller 9Where it is pressed against it while the twisted contact is supported 8Touch bridge 6, Across the static contact 4with 5The circuit is switched on 12By the spring 13The role of the top in the contact support 8Of the gap 3Fixed to the closed position.
3. 3Cam disk 3Continue to rotate.
3. 4Disconnect the cam 7Touch the roller 11Press on it to secure the catch 12So that the contacts are supported 8Release, the latter due to springs 10The role of the rapid rotation around its axis, the circuit breaking.

3. Use of the environment
4. 1, LK4The master controller is suitable for the following operating conditions:
4. 1. 1Altitude not exceeding 1000Meter;
4. 1. 2The ambient air temperature is not higher than +40Lt; 0 & gt; CAnd not less than -25Lt; 0 & gt; C (When the temperature is below -15Lt; 0 & gt; CUse a non-frozen lubricant when the temperature is below -25Lt; 0 & gt; Cto -40Lt; 0 & gt; C, The order should be specified).
4. 1. 3Air relative humidity is not greater than80%;
4. 1. 4In the absence of explosion hazard medium, and the medium is not enough to corrode the metal and damage the insulation of gases and dust (including conductive dust);
4. 1. 5No significant vibration and shock vibration of the place.
