Definitions
- Temporary elastic connection means are used between the movable resistance contact and its support element so that the movable resistance contact can take two defined positions.
- These temporary elastic connection means are composed of several balls 19, placed in holes and each pushed by a spring 18 towards the inner wall of the movable resistance contact 12, which comprises two series of notches 20 and 21 corresponding to the two positions of the means of temporary elastic connection.
- a first object of the invention is a medium or high voltage electrical switch, equipped with a mechanical device comprising:
- a contact carrier of the movable resistance insertion contact capable of passing the current flowing in the resistor
- At least one return spring constituting the energy storage system, which allows to return to its initial position the movable resistance insertion contact and which is placed between the contact carrier which is tubular, and the contact movable resistance insertion which is also tubular and integral with the control rod, the at least one return spring which can serve as a conductor vis-à-vis the resistance;
- the elastic connecting element between the movable resistance insertion contact and the control rod consists of the spring of the flexible toroidal helical type placed in a notch of the control rod (or the movable contact of insertion of resistance) and a groove of the control rod (or movable contact), and the device comprises one or more return springs.
- it comprises an intermediate contact for effecting the passage of the insertion current of the resistor between one end of the movable resistance insertion contact and the contact carrier.
- At least a portion of the insertion resistor is placed around the control rod.
- the first intended use of the switch according to the invention is provided for a resistance insertion device according to the invention can be used in parallel with the switch-off chamber of the switch on which the assembly is installed. It is recalled that the goal is to insert resistors for a time varying from four milliseconds to fifteen milliseconds in order to dissipate some of the energy that can cause overvoltages during closing operations under long power lines.
- the resistance insertion device makes it possible, in the resistance insertion contact, to return to the open position before the main contacts of the switch or circuit breaker have the time to close and reopen during the first time. a closing / opening operation. This is intended not to interfere with the switch or circuit breaker, during the opening operation, in particular so as to maintain the recovery voltage during the break. For this reason, the contacts of the resistor insertion device must be at a sufficient distance to allow to obtain certain recovery voltage, when opening the main contacts of the switch. or circuit breaker on which is installed the device according to the invention.
- the insertion device has a control rod 1, or a movement input link, which is directly linked to the travel of the main switch chamber of the switch or the circuit breaker, the races of which may be different.
- This control rod 1 is temporarily secured to a movable resistance insertion contact 2 whose end 2A is provided to come into contact with the end 6A of a fixed contact insertion resistance 6.
- All these elements are, in the embodiment described here, a shape of revolution about a common axis 10, which may preferably be parallel to the axis of the direction of movement of the main contacts of the switch or circuit breaker, to which the insertion device according to the invention.
- a contact carrier 3 makes it possible to maintain the assembly and to make the current flow, if necessary, for example if the control rod 1 is made of insulating material and the resistor itself, which is not not shown in this figure is placed around it.
- an intermediate contact 5 placed between the end of a contact carrier 3 and the movable contact for resistance insertion 2 is used.
- the contact carrier 3 serves as a guide for the moving contact of resistance insertion 2.
- the movable resistance insertion contact 2 comprises a shoulder 9 itself carrying a band 7 to guide its movements in the contact carrier 3.
- This contact carrier 3 is integral with the movable resistance insertion contact 2 and the control rod 1.
- One or more return springs 4 are placed in the cylindrical space formed between the inner face of the contact carrier 3 and the outer face of the movable resistance insertion contact 2.
- the return springs 4 can serve as drivers for -vis resistance to insert.
- the movable resistance insertion contact 2 as well as the control rod 1 have moved to the right until the end 2A of the movable insertion contact 2 penetrates inside. the end 6A and the fixed resistance insertion contact to establish the electrical contact between them and make the resistance operational. As a result, the springs 4 have been compressed.
- the temporary connection means between the control rod 1 and the movable resistance insertion contact 2 consist of a groove 1A, made on the outer surface of the control rod 1, of a helical coil spring 8 which is flexible and a notch 2B, made on the inner surface of the movable resistance insertion contact 2.
- the latter offers a resistance such that it pushes, via a shoulder 9, the movable resistance insertion contact 2 towards its position.
- the flexible toric coil spring 8 deforming under the pressure of the force. As a result, it leaves the notch 2B of the movable resistance insertion contact 2 and allows the latter to move back to its initial position.
- FIG. 4 shows this retracted position of the movable resistance contact 2.
- the control rod has slightly continued its translational movement along the axis 10, keeping the flexible coil spring 8 in its notch 1A.
- the interrupting chamber drives the control rod 1 in the opposite direction, that is to say it returns to the position of Figure 1, the coil spring 8 flexible found the notch 2B of the resistance insertion mobile contact 2.
- Another shock can be deliberately provoked in another way.
- a second type of spring may be added to the return springs 4, but having a different stiffness to cause a sudden increase in end-of-stroke forces. It can be seen that this system is relatively simple, while making it possible to achieve the going and the return of the movable resistance insertion contact.
- the flexible toroidal coil spring 8 used in the switch according to the invention is a known spring.
- This type of spring is of the type of the one marketed, inter alia, by the company BAL SEAL ENGINEERING.
