Electrical power is then available from lug 21 to the incoming heat sink In some embodiments the contact surface of the stationary contact could be bonded to the surface of the heat sink or be the actual heat sink itself.

When solenoid 27 is energized it pulls the armature to the right which in turn moves the contact frame 28 towards the solenoid While the stationary contact shown in the figures have been mounted on the upper surface of the heat sink, it is equally feasible in applications, where desirable, to mount the stationary contacts upon the lower surface or other areas of the heat sinks.
Similar limit switches could be installed on the movable frame 28 to sense the position of the incoming line contacts. Search Expert Search Quick Search.

When desired, solenoid 19b is actuated, shunting bar 15c engages stationary contacts 14e and 14f which are respectively mounted on heat sinks 12e and 12f srate a shunting current path between the heat sinks which is parallel to the control gated current flow via semiconductors 13e and 13f. A SumoBrain Solutions Company.
Because frame 35 is made of a non-conducting material, physical contact with the heat sink inner surfaces can act as a means to guide the frame 35 between its extremes of travel which also thereby controls the alignment between the movable contact piece 37 and the stationary contacts 38 and The starter control assembly of claim 26 wherein said solenoid is mounted on at least one of said line heat sinks.
In the case of the bypass current path, the heat sinks may have a stationary contact on both the incoming and outgoing heat sinks such as to provide a shunting starterr path between adjacent heat sinks and around the semiconductor. The complete assembly is isolated from electrical contact via mounting insulating feet 46a, 46b, 46c and 46d.

The starter control assembly of claim 1 wherein said stationary contact includes a renewable starteer surface of electrically conducting material rigidly attached to said heat sinks. The starter control assembly of claim 38 wherein said surface is coated with a wear resistance material. Incoming heat sink 22 is generally parallel spaced from outgoing heat sink The incoming solenoids such as 18a, 18b can be coordinated with the thyristor gating circuit to first phase off the thyristor, reducing the load current to a minimum or trickle value before opening contacts 16, To sense operation and coordinate the operation of the shunting contact, a switch element, such as limit switch 40, can be mounted to slid the position of the movable contact.
Benshaw’s experience in the design, production and installation of mission stafe motor controls and drives for continuous industries is reflected in every product they build.
Such statte can be carried away from the semiconductor devices through the use of heat sinks. When solenoid 9 is activated such as to connect stationary shunting bar 5 with contacts 4a and 4b, the load current passes from line heat sink 2a to load heat sink 2b via contact 4a, movable contact bar 5, and stationary contact 4b.

Also a single solenoid actuates a single shorting bar 15a which in turn contacts stationary contacts 14a and 14b. When the solenoid 34 is deenergized, return spring 34 pushes frame 35 upward causing the movable contact 37 to disengage physical and electrical contact with the stationary contacts 38 and Mounting assembly for semiconductive controlled rectifiers.
Soft Starter Panels in Faridabad. Simply adjust the “acceleration” ramp and when the motor is asked to start It’s the grandfather of the heap.

Due to the very slight resistive nature of the metallic conducting surfaces of contacts 4a, 4b, 5 the sub-assembly 1 would generate very little of the undesirable heat that is normally associated with solid state control devices.
Through the use of known gating circuits, such semiconductor devices can be used to control the power applied to a load, such as an AC motor circuit.
Brand Benshaw Fiber optic firing, and programmable MX3 controllers, deliver unprecedented functionality and performance. As shown in assemblies 11b and 11c, multiple assemblies may be ganged together and have their respective incoming movable contacts 17b and 17b’ actuated from a single electric solenoid 18b. Other embodiments would include the solenoid acting through mechanical linkage to drive a plurality of movable contacts.
Fiber optic firing, and programmable MX3 controllers, deliver unprecedented functionality and performance. When the semiconductors 30a and 30b are gated “off”, the load current is reduced to a very low leakage current level. Similarly the opening of shunting contacts 14, 15 can be coordinated with the gate circuit to occur only in the full-on state to minimize the voltage and arcing during current interruption at contacts 14, SSRVS is the thing of today!
