Description

Operator for circuit breaker

[0001] The present invention relates to an actuator for a circuit breaker, and more particularly, to an actuator for a circuit breaker configured with different coils so as to shorten the energization time when diagnosing a fault in a system.

[0002] The material described in this section merely provides background information for the present invention and does not constitute prior art.

[0003] When a power outage occurs on a distribution line, such as due to tree contact, reclosers installed in the system prevent the outage from spreading by interrupting the fault current. When a fault occurs, the recloser diagnoses and eliminates the fault by connecting and disconnecting (reclosing) the power source and load sides according to preset operational responsibilities.

[0004] However, when a fault occurs, the recloser first cuts off the power supply side and the load side and then re-energizes the power supply side and the load side to determine whether the fault has been resolved. This causes a problem in that the fault current flows into the system, damaging the devices that make up the system.

[0005] Therefore, in order to solve the problem caused by the reclosing operation of the existing recloser, the current flow time and magnitude for fault diagnosis after the initial blocking of the recloser when a fault occurs in the line must be minimized.

[0006] As a method for minimizing the current flow time and magnitude during fault diagnosis, a "pulse operation duty" has been proposed that diagnoses the fault status of the system based on a short-term pulse test of 3 to 8 ms, unlike the existing operation duty. In order to implement this pulse operation duty, the moving direction of the movable rod of the recloser actuator that connects or disconnects the power side and the load side (corresponding to the movable rod part of the present invention) must be able to quickly switch.

[0007] The present invention is intended to solve the above-described problem, and its purpose is to provide an actuator for a circuit breaker capable of minimizing the energization time between the power side and the load side for fault diagnosis.

[0008] In order to solve the above-described problem, the present invention provides an actuator for a circuit breaker that performs a high-speed cycle breaking operation, comprising: a frame portion made of a magnetic material, the frame portion having an upper plate having a front through hole and a rear through hole formed through the center of the front and rear sides thereof, the upper through hole being formed in the upper center, and a lower plate having a lower through hole formed in the lower center; a plunger portion having a plunger spaced apart from an outer lower direction of the lower plate and having a first through hole formed through the center; a first coil portion having a first coil inserted through the front through hole or the rear through hole, penetrating the frame portion, and having a second through hole formed through the center, the first coil portion applying a magnetic force in a direction corresponding to a current flowing in the first coil to the plunger portion; And a second coil part having a third through-hole formed through the center thereof, and spaced apart from the outer lower direction of the lower plate, spaced apart from the upper direction of the plunger part, and applying a magnetic force in a direction corresponding to a current flowing in the second coil to the plunger part, wherein the second coil part further includes a first coil member in the shape of a disk formed around the third through-hole so as to accommodate the second coil, and a second coil member in the shape of a cylinder that extends vertically in the direction of the first coil part by a predetermined length with a circumference shorter than the circumference of the first coil member, and from which the third through-hole extends simultaneously, wherein the second coil is a Thomson coil in the shape of a spiral and is disposed on the first coil member, the second coil is a solenoid coil in the shape of a spiral and is disposed on the second coil member, and the Thomson coil and the solenoid coil are integral.

[0014] The second coil portion may include a spaced arrangement portion installed so that the frame portion and the second coil are spaced apart from each other in the outer lower direction of the frame portion.

[0015] The control of at least one of the operations performing the high-speed cycle blocking operation can be selectively performed, and sequentially, (a) the current of the first coil part and the second coil part can be adjusted so that the plunger moves forward and backward, (b) the current of the first coil part can be adjusted so that the plunger moves forward, (c) the current of the second coil part can be adjusted so that the plunger moves backward, and (d) the current of the first coil part can be adjusted in the forward and reverse directions so that the plunger moves forward and backward.

This is a diagram showing the status.

[0050]

[0051] Referring to FIGS. 1 to 12ab, the circuit breaker actuator (10) of the present invention is an actuator for a circuit breaker that performs a high-speed cycle blocking operation, and includes a frame portion (100), a plunger portion (200), a first coil portion (300), a second coil portion (400), and a control portion (not shown).

[0052] Next, the circuit breaker actuator has a first coil portion (300) positioned at the center of the inside of the frame portion (100), a second coil portion (400) positioned at the lower outer side of the frame portion (100), and a plunger portion (200) positioned at the lower part of the second coil portion (400).

[0053] The frame (100) is made of a magnetic material, and the center of the front and rear sides are perforated to form a front through hole and a rear through hole.

[0054] And the frame part (100) has an upper plate (110) in which an upper through hole (111) is formed in the upper center, and a lower plate (120) in which a lower through hole (121) is formed in the lower center.

[0055] And the frame part (100) may include a first magnetic block (130), a permanent magnet (140), a second magnetic block (150), and a third magnetic block (160).

[0056] The first magnetic block (130) is placed at the lower portion of the upper plate (110), but is placed at the center of the upper plate (110), and a fourth through hole (131) corresponding to the upper through hole (111) can be formed at the center.

[0057] Permanent magnets (140) can be placed on the left and right sides of the first magnetic block (130).

[0058] The second magnetic block (150) can be placed on the left and right sides of the permanent magnet (140).

[0059] The third magnetic block (160) is placed on the left and right sides of the second magnetic block (150), respectively, and can be coupled to the lower part of the second magnetic block (150).

[0060] And the first magnetic block (130) and the second magnetic block (150) can be bolted and connected to the upper plate (110). Next, the third magnetic block (160) can be bolted and connected to the second magnetic block (150) at the upper part, and bolted and connected to the lower plate (120) at the lower part.

[0061] In addition, the second magnetic block (150), the permanent magnet (140), and the third magnetic block (160) can be arranged in both directions based on the first magnetic block (130).

[0062] In this way, the frame part (100) can be configured as a rectangular frame by the first magnetic block (130), the permanent magnet (140), the second magnetic block (150), the third magnetic block (160), the upper plate (110), and the lower plate (120).

[0063] The plunger portion (200) may be arranged to be spaced apart from the outer lower direction of the lower plate (120), but may be arranged to be spaced apart from the lower portion of the second coil portion (400). In addition, the plunger portion (200) has a plunger (210) in which a first through hole (211) is formed through the center. Here, a recessed groove (213) lower than the height of the plunger (210) may be formed on both sides centered on a plunger receiving groove (212) to be described later.

[0064] And the plunger part (200) may include a driving shaft (220), a driving plunger (230), a non-magnetic spacer (240), and a spring (250).

[0065] The driving shaft (220) can sequentially pass through the third through hole (411), the lower through hole (121), and the upper through hole (111). In addition, a plunger (210) can be placed on the upper portion of the driving shaft (220). At this time, the driving shaft (220) is coupled to the first through hole (211).

[0066] And the drive shaft (220) can be formed as a two-stage shaft so that the length can be adjusted in the upper and lower directions. However, this is only an example, and it can also be formed as a three-stage shaft so that the length can be adjusted in various ways.

[0067] The drive plunger (230) may be coupled to the lower side of the drive shaft (220). That is, the drive plunger (230) may be spaced apart from the lower side of the plunger (210). At this time, the drive plunger (230) may have a larger diameter than the plunger (210) and the third through hole (411). This may prevent the drive plunger (230) from flowing into the third through hole (411). In addition, the drive plunger (230) may have a through hole formed in the center so that the drive shaft (220) may pass through it.

[0068] The non-magnetic spacer (240) has the same area as the lower surface of the plunger (210) and can be bolted.

[0069] The spring (250) may be partially accommodated in the plunger receiving groove (212) formed by being inserted into the inside of the plunger (210). That is, a part (lower part) of the spring (250) may be accommodated in the plunger receiving groove (212), and the other part (upper part) may protrude upward from the plunger (210).

[0070] The first coil portion (300) is inserted through the front through hole (101) or the rear through hole (102), is positioned penetrating the frame portion (100), and has a first coil (310) having a second through hole (311) formed through the center, and applies a magnetic force in a direction corresponding to the current flowing in the first coil (310) to the plunger portion.

[0071] At this time, the first coil (310) may be a solenoid coil.

[0072] And the first coil portion (300) may include a mounting portion (320) in which the first coil (310) can be inserted and mounted through the interior of the frame portion (100).

[0073] This anchoring portion (320) may be in the shape of an 'I'. In the 'I' shape, the first coil (310) may be surrounded by a vertical bar, and the first coil (310) may be anchored to a horizontal bar in the shape of an 'I'. At this time, the anchoring portion (320) may also have a through hole formed therein.

[0074] The second coil portion (400) has a second coil (410) having a third through hole (411) formed through the center thereof. The second coil portion (400) is positioned spaced apart from the outer lower direction of the lower plate (120), but spaced apart from the upper direction of the plunger portion (200), and applies a magnetic force in a direction corresponding to the current flowing in the second coil (410) to the plunger portion (200).

[0075] And the second coil part (400) may further include a first coil member (430) in the shape of a disk formed around a third through hole (411) so that the second coil (410) can be accommodated, and a second coil member (440) in the shape of a cylinder that extends vertically in the direction of the first coil (310) to a predetermined length with a circumference shorter than the circumference of the first coil member (430), but from which the third through hole (411) extends simultaneously.

[0076] And the second coil (410) is a helical Thomson coil and is placed on the first coil member (430), and the second coil (410) is a helical solenoid coil and is placed on the second coil member (440). At this time, the Thomson coil and the solenoid coil may be integrated.

[0077] And the second coil portion (400) may include a spaced arrangement portion (420) installed in the outer lower direction of the frame portion (100) so that the frame portion (100) and the second coil (410) are spaced apart from each other.

[0078] The separation arrangement (420) has a square shape corresponding to the lower plate (120), and may include a pillar member (421) that is coupled to a placement hole (412) formed at each corner of the second coil (410) and is arranged in the upper direction of the second coil (410), and a coupling member (422) that is coupled in the direction of the pillar member (421), that is, from the lower to the upper direction of the second coil (410).

[0079] At this time, the second coil (410) may be a Thomson coil.

[0080] The control unit controls the current flowing in the first coil (310) and the second coil (410). The control unit can selectively control any one of at least one of the operations performing a high-speed cycle blocking operation.

[0081] And the control unit selectively controls one of at least one operation that performs a high-speed cycle blocking operation, and sequentially, (a) adjusts the current of the first coil part (300) and the second coil part (400) so that the plunger (210) moves forward and the driving plunger (230) moves backward. (b) adjusts the current of the first coil part (300) so that the plunger (210) moves forward. (c) adjusts the current of the second coil part (400) so that the driving plunger (230) moves backward. (d) The current of the first coil part (300) can be adjusted in the forward and reverse directions so that the plunger (210) moves forward and backward.

[0082] At this time, in Fig. 12a, the first coil section (300) may be used for the injection operation, and the second coil section (400) may be used for the high-speed opening operation. That is, the injection operation may be performed by driving the first coil section (300), and the opening operation may be performed by driving the second coil section (400). In this case, the opening operation may mean blocking.

[0083] At this time, the insertion and opening operations can be performed with the first coil section (300) in Fig. 12b. At this time, the opening can be a 2-3 cycle blocking.

[0084] Moreover, in Fig. 12, adjusting the current direction of the first coil part (300) so that the magnetism of the plunger part (200) applies the forward magnetic force to the plunger (210) is referred to as 'first open coil forward ON', and adjusting the current direction of the second coil part (400) so that the magnetism of the plunger part (200) applies the backward magnetic force to the drive plunger (230) is referred to as 'second coil ON'.

[0085] However, this is only an example, and both input and output can be driven by the first coil section (300).

[0086] The current direction of the first coil part (300) is adjusted so that the magnetism of the plunger part (200) applies a magnetic force acting backward to the plunger (210), which is referred to as 'first coil reverse ON'. That is, input and opening can be performed with the first coil part (300).
