Description

Technical Field

[0001] This invention relates to pole-mounted reclosing disconnect switches and reclosing devices, particularly commercial and residential disconnect switches, and more specifically, single-phase disconnect switches and the use of reclosing devices to form a stable power supply when the disconnect switches are open, the function of which relates to commercial and residential disconnect switches. Background Technology

[0002] Electricity generated by a power plant is transmitted through transmission lines and then supplied to the transmission line via a nearby distribution system. This distribution system is equipped with various protective and switching devices to ensure a stable power supply. As a protective device for the distribution lines, a disconnect switch is a switch that opens the power supply channel when a fuse trips in the event of an overcurrent or other event.

[0003] The primary side of the transformer is equipped with a switch to cut off the fault current (current flowing in when a power system fault occurs). If a transformer fault occurs, the fault current flows through the fuse inside the switch. The fuse is single-wire, and the circuit breaker is already open. To prevent power from flowing back into the transformer, the operator can use the switch to cut off any current supply to the transformer. The switch's function is also affected by the current flow. When the current flows, the fuse's energy is affected, and the tension of the fuse's lower fixing part is relieved, thus allowing the fuse hole to open freely under gravity.

[0004] Techniques for resolving situations where a cutting switch opens due to overcurrent or other reasons, techniques for having staff reset (or discard) fuses, and techniques for remotely monitoring fuse opening.

[0005] This technology always involves cutting off the switch to measure the lungs for a long time until a power outage occurs, resulting in huge economic losses. Using manual methods, on-site restoration takes a long time, and the power supply is disrupted before restoration, causing huge economic losses. In the case of remote monitoring and adjustment, the effective distance of remote adjustment is limited, so there is the problem of incurring high costs to build stable facilities.

[0011] The problem that the invention aims to solve

[0012] The present invention addresses the common problem of the current situation, and provides a device for solving the problem of the amount of power supply channel rapidly formed by the disconnect switch and the organic combination of the disconnect switch and the lung when the power is turned on.

[0013] Methods for solving problems

[0014] The present invention features a power supply cut-off switch, a power selection and extraction via a wire and connection port connected to or shielded by a closed loop, and a connection port that is shut off by the closed loop when the fuse of all the aforementioned selection and extraction and connected cut-off switches is discarded.

[0015] The aforementioned closed-circuit television system is characterized by being connected to the power supply lead via the aforementioned disconnect switch to form a load ATM line and a closed-circuit television system. Simultaneously, the fuse trips during operation, opening the closed-circuit television system.

[0016] Invention Effects

[0017] The present invention relates to a drought-resistant, lung-function-controlled power cut-off switch and a lung-controlled power cut-off switch. According to the device, the flow of time, etc., causes the power cut-off switch to be cut off, and the power supply to the lung is normal when the power cut-off switch is installed around the power cut-off switch. Especially on site, there is no need for operation by personnel or remote adjustment work. Instead, it is linked to the release action of the fuse of the cut-off switch and connected to the lung. It has the effect of preventing long-term power outages and safety accidents of personnel and long-term power outages caused by remote adjustment errors.

[0018] Furthermore, the cut-off switch and the same material used for the lungs make it easy to apply without visual repulsion or insecurity. Moreover, the lungs, with gray cut-off switches and these connecting (or blocking) switches, can be applied easily at a low price. Attached Figure Description

[0034] In describing this invention, detailed descriptions of the functions or components of the invention will be omitted if it is believed that such descriptions might unnecessarily obscure the essence of the invention. Furthermore, the terms used below are defined for their functionality according to the invention and may vary depending on the intent or convention of the user or operator. Therefore, their definitions should be based on the entire contents of this listing.

[0035] like Figure 1 As shown, the commercial and residential dual-use switch with the reclosing function of the present invention has its first and second reclosing switches (20, 30) connected in parallel with the power input line (1) and the load output line (2). The switch (20) used for disconnecting the switch (10) and the first reclosing switch (20) used for reclosing, as well as the switch (20) used for reclosing the switch (20) and the second reclosing switch (20) or the second reclosing switch (20, the second reclosing switch (20), or the second reclosing switch (20) used for disconnecting the switch (30). 50).

[0036] The first and second re-closing cut-off switches (20, 30) and the first and second switching means (40, 50), and their associated configurations, constitute the re-closing device of the main cut-off switch.

[0037] The cut-off switch (10) is a finished product widely used in the power distribution field, and the specific description is omitted.

[0038] The first and second reshutdown furnace cut-out switches (20, 30) use the same finished product as the cut-out switch (10). Although the reshutdown furnace device can be configured in various ways by using a commercial and residential cut-out switch, it is easy to use by using the finished product, which reduces visual aversion.

[0039] Because the main disconnect switch is closed again, the device remains in the open (closed) state. When the disconnect switch (10) is open, all configurations of the power supply lead (1) and load lead (2) can be made. This function can also be achieved by other means (e.g., connecting or disconnecting with the power supply lead (1) and load lead (2). However, in the event of an overcurrent or other event, the fuse will blow and the power circuit will be opened (the function of the existing disconnect switch). This will be beneficial to the stability of the power distribution system. Therefore, since the main phase disconnect switch is closed again, the device is best equipped with a disconnect switch.

[0040] For the purposes of this invention, the power supply lead (1) is connected only to the input side of the cut-off switch (10), and the load lead (2) is connected to the output side of the cut-off switch (10) and the first and second recirculation cut-off switches (20, 30).

[0041] The first and second recirculation disconnect switches (20, 30) are configured the same as the disconnect switch (10), and are interlocked with the power supply wiring (1) through the first and second switches (40, 50), respectively. That is, the first recirculation disconnect switch (20) is connected to the power supply wiring (1) through the first switch means (40), and the second recirculation disconnect switch (30) is connected to the power supply wiring (40)(1) through the second switch (50)(1).

[0042] The unspecified symbol 21 in the figure is the fuse of the first recombining furnace cut-off switch (20), 22 is the starting electrode, 23 is the electrode side elastic element, and 24 is the support element.

[0043] The first and second switches (40) have the same configuration. The specific configuration is explained using the first switch (40) as an example.

[0044] The first switching means (40) remains in the open state. If the fuse (11) of the cut-off switch (10) is opened (falls out), it is switched to the closed state. The power supply lead (1) and the first reshutdown furnace cut-off switch (20) are connected. A branch line from the power supply lead (1) is directly connected to this branch line. The power input side of the cut-off switch (10) (starting electrode (12) or electrode (12) is indirectly connected to the fuse (11)) is elastically connected (13), as shown in the figure. For example, the components connected to the first switching means (40) are conductors. For example, the switch-side elastic element (44) is connected to the starting electrode (12) through an electrical wire (44a), and the terminal (42) is connected to the starting electrode of the next position through an electrical wire (42a).

[0045] The first switching means (40) is configured to switch off when the fuse (11) of the cut-off switch (10) is opened (rotated) due to the opening action. That is, without using a separate sensor, it is linked with the rotation of the fuse (11), which can reduce the misoperation of the switching point.

[0046] like Figure 2 As shown, the first switching means (40) includes an electrical connection to the power input side of the cut-off switch (10), an electrical connection to a movable start switch (41), and an electrical connection to the power input side of the first reshutdown furnace cut-off switch (20). When the cut-off switch (41) is closed, it constrains the electrical connection to the terminal (42), and the start switch (41) to be separated from the terminal (42). Then, when the fuse (11) of the cut-off switch (10) is activated, it provides protection on the cut-off switch (41).

[0047] The outer casing (43) is a tubular structure with an internal space, open at both ends facing the cut-out switch (10) and the first re-closing furnace cut-out switch (20). Both ends are fixed to the fixed sides of the cut-out switch (10) and the first re-closing furnace cut-out switch (20) (e.g., a sheath or support (14) or a light fastener fixed to an insulator). The inner casing is equipped with a start switch (41), a terminal (42), and the aforementioned triggering means to prevent the start switch (41) from being malfunctioning due to external factors.

[0048] The housing (43) may include a guide that forms a curved shape toward the end of the start switch (41) to allow the start switch (41) to move smoothly. Alternatively, the guide may be a pocket shape for fixing the inner wall terminal (42).

[0049] The housing (43) consists of a hole through which the movable electrode (12) and the electrode-side elastic element (13) are not interfered with.

[0050] The start switch (41) is in the form of a rod. In order to reduce interference (friction) when moving toward the terminal (42), a semi-circular head is formed at the head that moves toward the terminal (42), which is composed of a size that can move back and forth inside the housing (43).

[0051] Terminal (42) is located inside the housing (43) and installed on the other side of the start switch (41). It can be fixed or elastically movable using a flexible member and is the input side of the first reshutdown furnace cut-off switch (20).

[0052] The triggering means includes a combination of a switch-side elastic element (44) and a trigger (45) for removing the start switch (41) from the terminal (42) when the cut-off switch (10) is closed, and connecting the start switch (41) to the terminal (42) when the cut-off switch (10) is open.

[0053] The switch-side elastic member (44) uses elastic force to move the start switch (41) onto the terminal (42). It is preferably a coil spring. A device that can contract and expand is installed inside the housing (43). One side is fixed to one end of the housing (43), and the other side is connected to the start switch (41).

[0054] If the start switch (41) is only connected to the switch-side elastic element (44), then the switch-side elastic element (44) is a conductor connected to one or more of the start electrode (12) and elastic element (13) of the cut-off switch (10).

[0055] The trigger (45) constrains the switch-side elastic member (44) to a compressed state, separating the start switch (41) from the terminal (42). The constraint of the displacement difference of the start electrode (12) or the displacement difference of the electrode-side elastic member (13) can be released by various methods. For example, a plate is formed, one side is fixed on the start electrode (12), and the other side is inserted into the housing (43) through a hole formed on the housing (43) to form an elastic member (44).

[0056] For example, the trigger (45) is generally rotatably mounted on the housing (43) via a central pivot pin, with one side connected to the movable electrode (12) and the other side acting as a latch to constrain the switch-side elastic member (44) into a compressed state. According to this configuration, when the fuse falls off and causes the movable electrode (12) to displace, the free pivot on one side of the trigger (45) rotates through the displacement (44), causing the switch-side elastic member (44) to disengage from the elastic member (44). Alternatively, the trigger (45) is fixed on one side to the starting electrode (12) and moves linearly away from the switch-side elastic member (44) when the starting electrode (12) is displaced.

[0057] In addition, the trigger (45) can also prevent the movement of the start switch (41) and its connection with the terminal (42) from the front of the start switch (41) (facing the terminal (42)) and then move outward from the front of the start switch (41).

[0058] In addition, the trigger (45) can also be located between the fuse (11) and the starting electrode (12) and fall freely when the fuse (11) falls off.

[0059] The outer casing (43) can form an open portion to avoid interfering with the operation of the trigger (45).

[0060] The trigger (45) is configured to return to its original position only by operator operation.

[0061] The second switch (50) is configured the same as the first switch means (40), including a start switch (51), a terminal (52), a housing (53), a switch-side elastic element (54), and a trigger (55).

[0062] The first and second shut-off switches (20, 30) can be installed together with the shut-off switch (10) on a guard plate.

[0063] According to the present invention, the main switch with reclosing function functions as follows:

[0064] 1. Turn off the cut-off switch (see [link]). Figure 1 ).

[0065] When the cut-off switch (10) is in the closed state, the power input line (1) and the cut-off switch (10) and the load output line (2) are electrically connected and power is supplied through this path.

[0066] At this time, the trigger (45) of the first switching means (40) fixes the elastic element (44) on the switch side in a compressed state, thereby moving the start switch (41) away from the terminal (42), that is, the first switching means (40) is in an open state, so the first switching means (40) cannot be energized. The first switching means (50) is in an open state, so the second switching means (50) cannot be energized. Of course, the second switching means (50) and the first switching means (40) maintain the same open state.

[0067] 2. Open the cut-off switch and connect the cut-off switch for the first reshutdown furnace (see [link]). Figure 3 ).

[0068] In the state of degree 1, if an event such as overcurrent occurs, the fuse (11) of the cut-off switch (10) will fall off and detach from the starting electrode (12). At this time, the electrode-side elastic element (13) compressed by the fuse (11) expands, and a displacement difference is generated between the electrode-side elastic element (13) and the starting electrode (12).

[0069] Thus, due to the displacement difference between the electrode-side elastic element (13) and the starting electrode (13), the trigger (45) releases the constraint of the switch-side elastic element (44), thereby causing the switch-side elastic element (44) to expand, causing the starting switch (41) to move toward the terminal (42), and the starting switch (41) to connect to the terminal (42).

[0070] Therefore, the power input line (1), the first switching means (40), the first re-closing disconnect switch (20), and the load output line (2) form a power supply path, so that the load is powered normally.

[0071] 3. Open the first reshutdown furnace shut-off switch and connect the second reshutdown furnace shut-off switch (see...). Figure 4 ).

[0072] In the state of degree 3, if an event such as overcurrent occurs, the fuse (21) of the first reshutdown furnace cutoff switch (20) will fall off, and the first reshutdown furnace cutoff switch (20) will, as described in the cutoff switch (10), generate a displacement difference between the electrode side elastic element and the starting electrode, and the starting switch (51) of the second switching means (50) will move and connect to the terminal (52).

[0073] At this time, the first switching means (40) is a trigger (45) that keeps the elastic element (13) on the non-constrained electrode side, so the switch (41) is connected to the closed state of the terminal (42).

[0074] Therefore, the power supply line (1), the first switching means (40), the second re-closing disconnect switch (30), and the load lead (2) form a power supply path, so that the load is powered normally.

[0075] In addition, the present invention can be configured as follows:

[0076] This includes a configuration that restores the start switch (41) and the switch-side resilient element (44) to the open position for reuse of the first and second circuit cut-off switches (20, 30), such as Figure 5 As shown, the start switch (41) (or the switch-side elastic element (44) includes a lever (46).

[0077] A lever (46) is formed around the start switch (41), and an elongated hole (43a) is formed in the housing (43) to prevent the start switch (41) from moving to the terminal (42), thereby causing the lever (46) to protrude outward. Since the start switch (41) and the lever (46) are inside and outside the housing (43), there are methods for assembling them, such as opening one side of the elongated hole (43a) to the outside, or assembling the lever (46) to the start switch (41) from the outside after inserting the start switch (41) inside the housing (43).

[0078] The diagram shows that the lever (46) is located only on one side of the start switch (41), but it can also be formed symmetrically on both sides.

[0079] In order to confirm the closed-circuit operation of the first and second switching means (40, 50) on-site or remotely, the housing (43) may include lights that illuminate when the start switches of the first and second switching means (40, 50) are connected to the terminals respectively, and a communication module that transmits their connection signals to the control room server.

[0080] In addition, to prevent the trigger (45) from malfunctioning, a safety device can be added by connecting the start switch (41) to the terminal (42).

[0081] like Figure 6 As shown, the safety device is described using the first reclosing circuit cut-off switch (20) and the first switching means (40) as examples. It includes a shielding plate (47) connected to the housing (43) to prevent the terminal (42) and the start switch (41) from being connected. The shielding plate (47) is connected to the fuse (11) of the cut-off switch (10) by wires (47a) and the like.

[0082] The shield (47) is not connected to the trigger (45), but to the fuse (11). Therefore, even if the start switch (41) moves toward the terminal (42) due to damage to the trigger (45), the fuse (11) will not fall off. The connection of the start switch (41) is blocked forward at the terminal (42). If the fuse (11) falls off, it will fall out of the housing (43). The start switch (41) will not interfere with the connection of the terminal (42).
