Description

ELECTRIC CIRCUIT OPENING AND CLOSING OPERATION DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric circuit open / close control device, and more particularly, to an electric circuit open / close control device suitable for opening and closing of a circuit breaker.

JEM-1195 (JEM: Japan Electrical Manufacturers' Association) defines the functional unit of a control center as a unit of one circuit of a motor control center equipped with equipment for main circuits and auxiliary circuits necessary to perform a predetermined function. . In this functional unit, an MCCB (wiring circuit breaker) is usually mounted in order to safely cut off a current during a short circuit. In order to simplify the operation of the circuit breaker and to have an interlock function that prevents the function unit from being drawn out when the wiring breaker is in the ON state, there is an electric circuit switching and operating device.

Patent Document 1 discloses that in order to mount a handle control device to a wiring breaker, a mounting seat is provided, the screw is fastened to the half panel together with the wiring breaker, and then the handle control device is screwed to the mounting seat. It is.

The electric circuit switchgear control device (hereinafter sometimes abbreviated as 'opening and closing control device') installed in the function unit of the control center has the function of ON, OFF, RESET operation of the circuit breaker, and ON, TRIP, OFF, RESET. It also functions to display status. In addition, the open / close operation device is connected to a knob of the circuit breaker and an operation knob through a link mechanism, so that the operation of the circuit breaker can be operated by operation of the operation knob. Is displayed on the design surface of the switching device.

The operating stroke of the operation knob of the switchgear is designed in accordance with the operation stroke of the knob of the circuit breaker, but the ON, TRIP, OFF and RESET positions of the circuit breaker have tolerances. There is a problem of shifting depending on the size of the tolerance of the circuit breaker. In addition, since the tolerances of the individual wiring breakers are not constant, even when the operating state of the wiring breakers is the same, when a plurality of functional units are lined up, the position of instruction of the operating state in the open / close control device is different, thereby providing a sense of uniformity. In this case, not only is it a problem, but it is also unclear whether or not the ON / OFF display device is ON.

9 and 10 illustrate in detail the problems of the prior art. The example where the instruction | indication position of the operation knob 2b shifted | deviated by the operation stroke (C of the following description) of the knob which turns a contact of a wiring breaker from OFF to ON is shown. When the stroke tolerance of the knob that turns the contact of the wiring breaker from ON to negative is negative tolerance, as shown in Fig. 9, the operation knob 2b instructs the front immediately at the ON display position in the design. In the case where the stroke tolerance is a positive tolerance, as shown in Fig. 10, the operation knob 2b is instructed past the ON display position in the design. For this reason, in a control center in which a plurality of functional units are stored, the tolerances of the wiring breakers are different from each other. As shown in Fig. 9, if the instruction of the operation knob 2b is immediately before the ON display position, there is a problem that the reliability of the ON display itself is suspected.

Embodiment 1

The circuit breaker causes an accident due to an arc or the like at an internal contact when its knob (knob) is operated very slowly. Therefore, regardless of the operating speed, when the knob moves from the OFF position of the contact to a certain position (hereafter, this position is called dead point), the feeding mechanism can be used quickly even if the knob does not move to the ON operation completion position. If the knob is moved to a certain position (hereinafter called a dead point) from ON to OFF on the contrary, the contact is closed quickly by the pulling mechanism even if the knob is not moved to the OFF operation completion position. It is well-known that there is a thing which carries the mechanism to make it open. As what mounts such a thing, the Mitsubishi Denki Corporation breaker model name NF250-SW, NF250-HW, patent document 2, etc. are commercially available, for example.

The circuit breaker equipped with this mechanism moves the internal contact to the ON and OFF normal position even when no external force is applied to the knob at the position beyond the dead point. In addition, even if the driving force by the external force is not applied at the position beyond the dead point, the knob of the wiring breaker is driven to the operation completion position by the operation force of the closing and pulling mechanism.

In Embodiment 1, as shown in FIG. 6, the tolerance of the knob 2k which makes the operation stroke A of the operation knob 2b which operates a contact from OFF to ON anticipate the contact of a circuit breaker from OFF to ON is estimated. By designing a stroke smaller than the minimum operating stroke (C) and exceeding the dead point of the feeding mechanism, when the operation knob 2b is in the ON position (6), the wiring breaker is turned to the ON completion position (7) by the knob (2k). ) Does not move, the driving force by the feeding mechanism of the wiring breaker is applied to the operation knob 2b. Since the driving force of the closing mechanism of the wiring breaker is continuously applied to the operation knob 2b, by providing a stopper (described later) on the operation knob 2b so that the operation knob 2b does not rotate beyond the ON display position (described later), The instruction position of the operation knob 2b is held at the position (display position) determined by the stopper without being influenced by the operating stroke tolerance of the wiring breaker.

6 is a view for explaining the relationship between the operation knob of the first embodiment and the operation stroke of the knob of the circuit breaker. C is the operating stroke (angle) of the knob 2k which turns the contact of the circuit breaker from OFF to ON. A is the operation stroke (angle) of the operation knob 2b for operating the contact from OFF to ON, and is indicated by the stroke (angle) of the knob 2k of the circuit breaker caused by the operation knob 2b. B is the operating stroke (angle) when the operation knob 2b is rotated in the opposite ON direction from the OFF position to reset. D is the operating range of the knob 2k. A + B is the operation range of the operation knob 2b.

When the circuit breaker opens the contact (TRIP) due to abnormality such as a short circuit, it can be reused by returning the contact to OFF again by performing RESET operation. This RESET operation requires a stroke larger than the OFF position of the knob (that is, it needs to rotate in the half ON direction from the OFF position of the knob). As such a thing is mounted, the said Mitsubishi Denki Corporation breaker etc. are mentioned, for example. In this case, in order to perform the RESET operation with the operation knob, a stroke that can be operated beyond the OFF position (that is, rotating the operation knob in the half ON direction from the OFF position) is required. The stopper is not provided, and the OFF display position indicated by the operation knob is shifted due to the operating stroke tolerance of the wiring breaker.

In Embodiment 1, the ON display uses the mechanism related to the operation handle as described above, while in the OFF display, a backlash (slack) is provided in the link mechanism between the knob and the operation handle when the circuit breaker is OFF. The driving force by the pull mechanism when the circuit breaker is OFF is not applied to the operation knob, and the operation handle when the circuit breaker is OFF is provided by slightly engaging the mechanism part of the operation knob at the OFF position of the operation knob. By providing an OFF position stop mechanism for stopping the operation handle at the OFF position or its vicinity, the shift of the OFF position of the operation handle is prevented.

1 to 5 illustrate Embodiment 1 of the present invention, FIG. 1 is a front view of a functional unit of a control center, FIG. 2 is a side view of FIG. 1, FIG. 3 is a partially enlarged view of FIG. 1, and FIG. 4 is FIG. 3 is a partially enlarged rear view of the state in which the link mechanism of the operation handle of FIG. 3 is removed. In each drawing of the specification, the same code | symbol may be attached | subjected to the same or equivalent part, and description may be abbreviate | omitted partly.

In FIG. 1 and FIG. 2, the functional unit 1a of the control center has a connector 1b connected to a power supply, and includes an electrical circuit open / close operation device including a circuit breaker 1c and a circuit breaker 1c as an example of a circuit breaker. Realizing the operating device 1d, the current sensor image current transformer 1e, the electromagnetic switch 1f, the control circuit protection fuse 1g, the control circuit terminal block 1h, and various sequences. And a connector 1k for transmitting electric power from the functional unit to the load.

In Figs. 3 to 5, the opening and closing operation device 1d is a design panel 2c for displaying the operation state (ON, OFF state, etc.) of the wiring breaker 1c, the operation handle 2b, and the wiring breaker 1c. Cam 2g, which drives the knob 2k of the circuit breaker 1c by rotating the mounting lug 2d and the operation knob 2b for assembling and fixing the panel 2c in the function unit 1a of the control center. (2e) and the link mechanism (2f) and the link mechanism (2f) for driving the knob (2k) of the circuit breaker (1c) in conjunction with the cam (2e) in conjunction with the cam (2e) to hold the mechanism portion wiring breaker ( It consists of the mounting bracket 2g attached by 1c), the stopper 4d provided in the design panel (fixing side), and the interlock mechanism 2h of a functional unit.

The operation knob 2b is connected via the knob 2k of the circuit breaker 1c and the link mechanism 2f, and the operation knob 2b is rotated to drive the knob 2k to open and close the wiring breaker 1c. do. The cam 2e is integrally coupled to the operation knob 2b by a shaft, connected to the link mechanism 2f by an eccentric shaft 2n coupled to the cam 2e, and linked by rotation of the cam 2e. The mechanism 2f moves in a substantially straight line shape, and the knob 2k connected to the link mechanism 2f can be driven in a substantially straight line shape.

The stopper 4d stops the operation knob 2b at the ON display position. That is, the position where the operation knob 2b is stopped by the stopper 4d is the position on the design panel 2c instructed by the operation knob 2b at the stopped position and coincides with the ON display position of the design panel 2c. (See Figure 5). The cam 2e is pressurized (arrow) through the knob 2k and the link mechanism 2f by the driving force of the feeding mechanism of the wiring breaker 1c at the ON display position of the operation knob 2b, and the stopper 4d is pressed. (Arrow), the position on the design panel 2c indicated by the operation knob 2b is held at the ON display position of the design panel 2c. In addition, the wiring breaker 1c includes a contact portion, and is composed of a closing mechanism, a pulling mechanism, and a knob 2k for performing ON, OFF, and RESET operations.

In Embodiment 1, in order to prevent the shift | offset | difference of the position indicated by the operation knob 2b and the ON display position on a design panel, as mentioned above, the operation stroke of the operation knob 2b which operates a contact from OFF to ON is performed. The contact of the circuit breaker 1c is shorter than the operating stroke of the knob 2k which turns the switch from OFF to ON and exceeds the dead point of the feeding mechanism of the circuit breaker 1c. In short, as a result, the operation knob 2b is rotated from the OFF position to the ON direction, and the knob 2k is driven through the cam 2e, the eccentric shaft 2n, and the link mechanism 2f, thereby disconnecting the wiring breaker 1c. When the dead point of the closing mechanism of the circuit breaker is exceeded, the contact of the wiring breaker 1c is closed, and the knob 2k, the link mechanism 2f, and the eccentric shaft 2n are driven by the driving force of the closing mechanism of the wiring breaker 1c. , The operation knob 2b is driven and pressurized through the cam 2e, and the operation knob 2b is turned ON by pushing the cam 2e of the operation knob 2b with the stopper 4d. It is held in position to indicate status.

Therefore, although the cam 2e cannot rotate beyond the ON position 7 (FIG. 6) of a contact, since the driving force of the feeding mechanism of the wiring breaker 1c is continuously applied to the cam 2e, operation handle ( 2b) is held at the ON display position on the design panel, and the operation knob 2b can display the ON display position of the design panel 2c with high accuracy.

Embodiment 2 Fig.

7 and 8 illustrate Embodiment 2, where FIG. 7 is another partially enlarged view corresponding to FIG. 3 installed in the functional unit of the control center, and FIG. 8 is a sectional view taken along the arrow line of FIG. It is removed. 7 and 8, the OFF position stopper is composed of a small projection 5c provided in the operation handle 2b and an elongated groove hole 5d provided in the design panel 2c.

To turn off the circuit breaker 1c when the wiring breaker 1c is in the ON state, the operation knob 2b is operated from the ON side of the contact to the OFF direction, and is operated through the operation knob 2b and the link mechanism 2f. If the connected knob 2k is driven to a certain position (hereinafter referred to as a dead point) from the ON of the contact to the OFF direction, the wiring breaker 1c does not move even if the knob 2k does not move to the OFF operation completion position. ), The contact is opened quickly by the pulling mechanism. At this time, even if no external force is applied to the knob 2k at the position beyond the dead point, the internal contact moves to the OFF normal position. Moreover, even if the driving force by the external force is not applied at the position beyond the dead point, the knob 2k of the circuit breaker 1c is driven to the operation completed position by the driving force of the pulling mechanism.

When the knob 2k of the circuit breaker 1c is driven to the operation completed position, the operation knob 2b connected through the knob 2k and the link mechanism 2f is also rotated, but in the second embodiment, the contact of the circuit breaker is closed. A backlash (gap) is provided in the link mechanism between the knob 2k and the operation knob 2b when the wiring breaker 1c is OFF so as not to be affected by the tolerance of the operating stroke of the knob from ON to OFF. The driving force by the pulling mechanism at the time of OFF of (1c) is not applied to the operation knob 2b until the end, and the mechanism part of the operation knob 2b is slightly in the OFF position of or near the operation knob 2b. Make a jam.

That is, if the small protrusion 5c is provided in the operation handle 2b at the OFF position of the operation handle 2b, or the groove hole 5d is provided in the design panel 2c, the operation handle 2b will be provided. When operating to the place where the designation panel 2c indicates the OFF display position, the small projection 5c is fitted into the groove hole 5d, and as a result, the operation handle 2b is stopped at the OFF display position. As the small projection and the groove hole are in the opposite relationship, the small projection may be provided on the design panel 2c side with the groove hole on the operation handle 2b side.

Thus, the breaker is designed so that the driving force by the pulling mechanism at the time of turning off the contact of the wiring breaker 1c is not applied to the operation handle 2b from the knob 2k to the end via the link mechanism 2f. The operation knob 2b is stopped by the OFF position stop mechanism at or near the position where the operation knob 2b indicates the OFF state of the design panel 2c, without being influenced by the tolerance of the operating stroke of the knob from ON to OFF. The shift of the OFF display position of the design panel 2c instructed by the operation knob 2b can be prevented. In addition, Embodiment 2 can be implemented in addition to Embodiment 1.

As mentioned above, although this invention was demonstrated in detail by Embodiment 1, 2, this invention is not limited to these embodiment, Comprising: Various deformation | transformation form based on the spirit of the subject which this invention is trying to solve, and the solution means is also included. do. For example, the wiring breaker may be a wiring breaker mounted at a place other than the functional unit of the control center, or may be a shape other than the shape shown in Figs.
