Definitions
- the invention relates to the operation in electric power distribution lines, in particular with mechanical devices that allow safety during maintenance or repair work on said distribution lines.
- circuit breakers are required to protect the equipment connected to the network from overloads. During maintenance or repair processes, said circuit breakers must be opened to interrupt the flow of electrical energy and allow safe intervention of the equipment. Said opening requires, as a rule, the use of an arc extinguishing tool (load disconnector) to certify the safety of both the operator and the network equipment:
- the most commonly used arc extinguisher or load disconnector is the Loadbuster ® which provides arc extinction for a large number of devices such as disconnectors, circuit breakers, power fuses or limiting fuses.
- the device must be mechanically coordinated with the operating sequence of the Loadbuster in such a way! that (a) The hitching of the Loadbuster does not cause or allow the sectioning knife or the fuse tube to open prematurely and (b) The holding hook keeps the Loadbuster effectively anchored until the trip occurs at the same time ( c) Allowing the rapid removal of the Loadbuster whether the
- the present invention provides a novel adapter device that allows the safe and efficient use of! Loadbuster even in circuit breakers that do not have fastening hooks.
- the invention provides a mechanical device that serves as an adapter for e! Loadbuster and allows the opening of circuit breakers that do not count with opening support, which provides a hitch of the Loadbuster to! circuit breaker disconnection mechanism.
- Said device of the invention allows the conduction of the electric energy discharged through the Loadbuster, which results in an efficient arc extinction and therefore safe operation is guaranteed.
- the power line is contacted by means of a conductive bar that allows the passage of electricity, and once positioned, the Loadbuster is normally attached to the ring of the pipe and the whole system can be pulled to disconnect the electrical circuit,
- Figure 1 corresponds to the Loadbuster @ commercial arc extinguisher.
- Figure 2 shows a circuit breaker that has fastening hooks to hook the arc extinguisher.
- Figure 3 corresponds to the coupling of the Loadbuster arc extinguisher to said circuit breaker and the operation with the pole for opening the circuit breaker.
- Figure 4 shows a circuit breaker that lacks fastening hooks for the attachment of the arc extinguisher.
- Figure 5 corresponds to the adapter device of the invention.
- Figure 6 shows a side view of said adapter device.
- Figure 7 is a top view of the adapter device of the invention.
- Figure 8 shows e! adapter device of the invention coupled to the Loadbuster arc extinguisher.
- Figure 9 corresponds to the arrangement of the adapter device of the invention fitted to the Loadbuster in use on a pole,
- Said equipment has circuit breakers that protect against overload and allow said power flow cut-off for operation on the network, the most commonly used circuit breakers being the so-called pole-type circuit breakers.
- Said Loadbuster is coupled to a pole and maneuvered to perform the opening of!
- the circuit breaker however, said circuit breaker must comply with a series of technical characteristics, mainly it must have a fastening hook that allows the Loadbuster to be attached.
- the present invention provides a novel solution to this problem, providing an adapter device that it serves as a bridge between the circuit breaker and the Loadbuster arc extinguisher, and that allows the safe operation in the distribution networks regardless of whether the circuit breakers do not have hooks for the coupling of! Loadbuster
- Figure 1 shows the Loadbuster ® commercial arc extinguisher that is commonly used within the opening of circuit breakers, which has an articulated hitch at its top that attaches to the fastening hooks of the circuit breakers.
- Figure 2 shows a circuit breaker suitable for coupling with the Loadbuster arc extinguisher.
- FIG. 2 illustrates that the suitable short circuit for the coupling with the Loadbuster has two hooks on the top of the fuse tube, which, as evidenced in Figure 3, allow the coupling of! Loadbuster and, as a result of the force on the pole, the safe opening of the circuit breaker is achieved.
- Figure 5 shows an adapter device of the invention, which is designed to be firmly and securely coupled to the Loadbuster arc extinguisher and to allow hitching and opening of the rod.
- Said adapter device of the invention is constituted by fastening means that allow the coupling of Loadbuster, a mobile arm that allows the mechanical movement of the adapter and two rods attached to said arm, the first of them of contact (10) and the second of they guide (11).
- the fastening means include a press (1) inserted into a jaw (2) which has a threading system (3) that allows its adjustment.
- a fastener ⁇ 8. is fixed by means of a clamping screw (9), said strap allows the electrical contact between the adapter device and the arc extinguishing equipment "Load uster ".
- the movable arm (7) is L-shaped with a degree of inclination between 0 or 120 °, arm that is attached to the press (1) by means of a pin (6 ) and is adjusted by means of two retaining rings (5).
- Said mobile arm (7) has two holes in which the guide rod (11) is inserted first and then the contact rod (10), rods that are attached to the mobile arm (7) by means of knobs (12) as shown in Figure 7.
- the guide rod (11) ensures the location of! system to the electrical point, so that precision is made when performing the operation with the Loadbuster pole coupled to the device of the invention,
- the contact rod (10) is located in the power line, allowing the passage of current and thus ensuring the proper functioning of the Loadbuster arc extinguisher,
- the contact rod (10) has a rounded end, more particularly it has a semi-sphere coupled at its outer end that allows to reach eS end point of displacement of the contact rod when opening the circuit breaker. Also, this end facilitates the adjustment of the contact rod to the guide rod,
- the contact rod (10) is made of an electrically conductive material, for example steel.
- the movable arm (7), the press (1) and the clamp (2) are made of electrically conductive materials, preferably the movable arm (7) is made of steel and the press (1) and ia Jaw (2) are made of aluminum.
- Figure 8 shows e! attach the adapter device of the invention to the Loadbuster arc extinguisher.
- the press and the jaw imprison the articulated hook of the Loadbuster, and this hook is secured with the threading system (3).
- Figure 9 shows the adapter device of the invention already coupled to the Loadbuster on a pole, and the use of said coupled device for opening Sa of a circuit breaker that does not have grip hooks.
- said adapter device of the invention allows the opening of the rod safely, similar to how it would occur if these circuit breakers had the grab hooks, also ensuring e! proper operation of the Loadbuster arc extinguisher, since once the coupling between the adapter device of the invention and the Loadbuster is positioned, the latter normally joins the ring of the shaft and can be pulled out of the system to disconnect the electrical circuit .
