Description

Technical Field

[0001] This utility model relates to the field of mechanical maintenance technology, and in particular to an offline debugging instrument for electric actuators. Background Technology

[0002] Electric actuators are widely used in critical systems of nuclear power units, and their availability is directly related to nuclear safety, serving as a crucial guarantee for nuclear safety. Traditional electric actuators operate on two main principles: the first is that a three-phase motor, when energized, rotates in both directions, driving an internal transmission gear, which in turn moves the valve stem up and down at a constant speed; this is the most common method in process systems. The second type is used for dampers that require rapid closing or opening under special operating conditions. In this type of electric actuator, after the motor reaches its designated position, an internal spring stores energy, and a brake device is energized to maintain the current position. When power is lost, the brake releases, the spring quickly releases, and the damper opens or closes rapidly.

[0003] Existing offline debugging instruments do not include the control principle of the brake device, and therefore cannot meet the offline debugging requirements of the second type of electric actuator. Online debugging is the only option, which is not only cumbersome and wastes human resources, but also carries the risk of human error in information transmission. Utility Model Content

[0068] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0069] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features. "Multiple" means two or more, unless otherwise explicitly defined.

[0070] The terms used above are for ease of description only and should not be construed as limitations on this technical solution.

[0071] The offline debugging instrument for electric actuators provided in this embodiment of the invention is used for offline debugging of electric actuators. The electric actuator includes a control terminal, a brake device, and a power terminal.

[0072] like Figure 1 As shown, the offline debugging instrument includes: control terminal interface module 01, brake trigger module 02, and mechanism action module 03.

[0073] The control terminal interface module 01 is electrically connected to the brake trigger module 02 and the mechanism action module 03.

[0074] The control terminal interface module 01 is used to connect to the control terminal of the electric actuator and control the energization and de-energization of the brake trigger module 02 and the mechanism action module 03; the mechanism action module 03 is used to drive the power end; the brake trigger module 02 is used to drive the brake device.

[0075] Specifically, using an offline debugging instrument, the brake trigger module 02 is connected to the brake device of the electric actuator. When the brake trigger module 02 is powered on, the brake device is triggered. The control terminal interface module 01 is connected to the control terminal of the electric actuator to receive the electrical signal from the control terminal. At the same time, the control terminal interface module (01) controls the energization and de-energization of the brake trigger module 02 and the mechanism action module 03 through its internal circuit.

[0076] This utility model enables offline debugging of electric actuators through control terminal interface module 01, brake trigger module 02, and mechanism action module 03, reducing the risks and time of on-site debugging.

[0077] In some executable embodiments, such as Figure 2 As shown, the control terminal interface module 01 includes: a control terminal interface circuit 101 and a motor brake control circuit 102.

[0078] Specifically, the control terminal interface circuit 101 and the motor brake control circuit 102 can be separated into two independent circuits, each powered separately by a rectifier or rectifier circuit. Separating them reduces interference and increases the reliability of the control terminal interface module 01. The motor brake control circuit controls the energization and de-energization of the brake trigger module 02 and the mechanism action module 03. The control terminal interface circuit 101 and the motor brake control circuit 102 are electrically connected.

[0079] Furthermore, the power supply and de-energization of the motor brake control circuit 102 can be controlled through the control terminal interface circuit 101.

[0080] The control terminal interface circuit 101 includes: a power-on circuit and a power-off reset circuit.

[0081] Understandably, independent power-off reset and power-on circuits can independently test the operating status of the electric actuator under energized conditions and during power-off reset. This invention, through separate power-on and power-off reset circuits, can test the operating status of the brake device under three conditions: energized, de-energized, and reset after power-off.

[0082] In some scenarios, the operating status of the power end in the electric actuator can be tested simultaneously under three conditions: power-on, power-off, and reset after power-off.

[0083] The motor brake control circuit 102 includes a brake control loop.

[0084] Specifically, the brake control circuit controls the energization and de-energization of the brake trigger module 02 through an electrical connection with the brake trigger module 02.

[0085] The power failure reset circuit is connected in parallel with the power-on circuit.

[0086] Understandably, connecting the power-off reset circuit and the power-on circuit in parallel ensures that they do not interfere with each other during operation. For example, when the power-on circuit is disconnected, it does not affect whether the power-off reset circuit is disconnected.

[0087] There is an electrical connection between the power failure reset circuit, the power-on circuit, and the brake control circuit.

[0088] Specifically, both the power-off reset circuit and the power-on circuit can control the power-on and power-off of the brake control circuit.

[0089] The power failure reset circuit and the power gain circuit jointly control the on / off state of the brake control circuit.

[0090] When the power failure reset circuit is active, the brake control circuit will be disconnected regardless of whether the energized circuit is active. When the power failure reset circuit is disconnected, the brake control circuit will also be active when the energized circuit is active. When the power failure reset circuit is disconnected, the energized circuit switches from active to disconnected, and the brake control circuit remains active.

[0091] In some executable embodiments, such as Figure 3 As shown, the energized circuit includes a control terminal interface 1102 for connecting the control terminal of the electric actuator and the coil 1101 of the first relay.

[0092] Specifically, the control terminal interface 1102 can receive electrical signal information from the control terminal of the electric actuator and can control the opening and closing of the power supply circuit according to the opening and closing of the control terminal of the electric actuator.

[0093] The control terminal interface 1102 is connected to the coil 1101 of the first relay.

[0094] Understandably, connecting the control terminal interface 1102 to the coil 1101 of the first relay ensures that the on / off states of the control terminal interface 1102 and the coil 1101 of the first relay are consistent.

[0095] like Figure 4 As shown, the brake control circuit includes the coil 1201 of the first contactor, the first auxiliary contact 1202 of the first contactor, and the first auxiliary contact 1203 of the first relay.

[0096] It should be noted that when the coil 1101 of the first relay is energized or de-energized, it controls the closing of the first auxiliary contact 1203 of the first relay. The relay provides isolation between the energized circuit and the brake control circuit, ensuring that the currents in different circuits do not interfere with each other, thus enhancing the safety of the system.

[0097] The first auxiliary contact 1202 of the first contactor and the first auxiliary contact 1203 of the first relay are connected in parallel.

[0098] Understandably, if either the first auxiliary contact 1202 of the first contactor or the first auxiliary contact 1203 of the first relay is connected, the brake control circuit will be energized. After the brake control circuit is energized, the brake trigger module 02 will be turned on, thereby providing power to the brake device of the electric actuator and driving the brake device.

[0099] The first auxiliary contact 1202 of the first contactor and the first auxiliary contact 1203 of the first relay are connected in series with the coil 1201 of the first contactor.

[0100] When the first auxiliary contact 1203 of the first relay closes, activating the brake control circuit, the coil 1201 of the first contactor is energized, and the first auxiliary contact 1202 of the first contactor closes, energizing the motor brake control circuit. When the first auxiliary contact 1203 of the first relay opens again, the first auxiliary contact 1202 of the first contactor remains closed. Therefore, the brake control circuit remains active, and the brake trigger module 02 remains active, keeping the brake device running.

[0101] The control terminal interface circuit 101 and the motor brake control circuit 102 are electrically connected through the coil 1101 of the first relay and the first auxiliary contact 1202 of the first contactor.

[0102] When the control terminal interface circuit is energized, the motor brake control circuit is energized, thereby driving the brake device and power end of the electric actuator to operate.

[0103] Furthermore, when the control terminal interface circuit is energized, the coil 1101 of the first relay is energized, thereby closing the first auxiliary contact 1203 of the first relay and energizing the motor brake control circuit.

[0104] In some executable embodiments, such as Figure 5 As shown, the power failure reset circuit includes a coil 1103 of the second relay and a power failure reset hold button 1104.

[0105] The coil 1103 of the second relay and the power failure reset button 1104 are connected in series.

[0106] Specifically, when the power failure reset hold button 1104 is energized, the power failure reset circuit is activated, and the coil 1103 of the second relay is energized.

[0107] like Figure 6 As shown, the brake control circuit also includes: the first auxiliary contact 1204 of the second relay.

[0108] Specifically, when the coil 1103 of the second relay is energized, the first auxiliary contact 1204 of the second relay is disconnected.

[0109] The first auxiliary contact 1204 of the second relay is connected in series with the coil 1201 of the first contactor, the first auxiliary contact 1202 of the first contactor, and the first auxiliary contact 1203 of the first relay.

[0110] Specifically, when the first auxiliary contact 1204 of the second relay is disconnected, the brake control circuit is disconnected.

[0111] When the power failure reset retain button 1104 is open, the coil 1103 of the second relay is de-energized, and the first auxiliary contact 1204 of the second relay is closed.

[0112] When the power failure reset retain button 1104 is closed, the coil 1103 of the second relay is energized, and the first auxiliary contact 1204 of the second relay disconnects the brake control circuit.

[0113] The power-off reset circuit can hold the coil 1103 of the second relay and the button 1104 in place. The power-off reset circuit can control the motor brake control circuit to disconnect immediately, thereby controlling the brake trigger module 02 to be de-energized. When the brake trigger module 02 is de-energized, the brake device is also de-energized and stops operating.

[0114] The power failure reset circuit can immediately cut off the motor brake control circuit through the power failure reset hold button 1104, and ensure that the brake trigger module 02 is quickly powered off to ensure test safety and improve the test efficiency of the brake device.

[0115] In some executable embodiments, the motor brake control circuit 102 further includes a motor control loop.

[0116] The motor control circuit and the brake control circuit are connected in parallel.

[0117] Specifically, the parallel connection of the motor control circuit and the brake control circuit can control the mechanism action module 03 and the brake trigger module 02 respectively, so that the brake trigger module 02 controls the brake device and the mechanism action module 03 controls the power end independently.

[0118] like Figure 7 As shown, the motor control circuit includes the second auxiliary contact 1205 of the first relay and the coil 1206 of the second contactor.

[0119] like Figure 8 As shown, the mechanism action module 03 includes an action interface 302 for connecting the power end and a first auxiliary contact 301 of the second contactor.

[0120] Effective communication and control are achieved between the motor control circuit and the mechanism action module 03 to ensure that the power end can accurately execute actions according to the control signal.

[0121] The action interface 302 is connected to the first auxiliary contact 301 of the second contactor.

[0122] When the second auxiliary contact 1205 of the first relay is closed, the coil 1206 of the second contactor is energized, the first auxiliary contact 301 of the second contactor is closed, and the operating interface 302 is energized.

[0123] Specifically, when the first relay is energized, the second auxiliary contact 1205 of the first relay controls the energization state of the second contactor coil, thereby controlling the start and stop of the power end.

[0124] In some executable embodiments, the mechanism action module 03 further includes an action switch group 303 for controlling the direction of motion of the electric actuator.

[0125] The actuating switch group 303 is connected in series with the first auxiliary contact 301 of the second contactor.

[0126] The first auxiliary contact 301 of the second contactor is used to control the connection and disconnection between the action switch group 303 and the electric actuator.

[0127] In the early stage of commissioning of the electric actuator, the direction of action of the power end of the electric actuator is selected according to the action switch group 303, such as clockwise or counterclockwise rotation.

[0128] In some feasible embodiments, the energized circuit further includes: an energized hold button and a limit selector switch; the energized hold button and the limit selector switch are connected in series.

[0129] The limit selector switch includes a limit selector coil 1105, an open limit contact 1106, and a closed limit contact 1107.

[0130] The limit selection coil 1105 is connected to the control terminal interface 1102; the control terminal interface 1102 is electrically connected to the open limit contact 1106 and the close limit contact 1107 of the control terminal connected to the electric actuator.

[0131] The energized hold button is used to control the energization and de-energization of the energized circuit; the limit selector switch is used to limit the movement or position of the power end.

[0132] The open limit contact 1106 and the closed limit contact 1107 are part of a limit selector switch, corresponding to the open and closed positions of the power end, respectively. When the power end reaches these positions, the corresponding contacts are triggered, sending signals to the control interface 1102. The limit selection coil is connected to the control interface 1102 to receive control signals and control the action of the power end when it reaches the open or closed limit.

[0133] The limit selector switch selects the corresponding open or closed limit position based on whether the power end is energized to open or energized to close. Its normally closed contact is connected to the circuit. After the electric head reaches its position, the power supply to the energized circuit is disconnected, thereby disconnecting the power supply to the mechanism action module 03 and de-energizing the power end. The energized action and de-energized reset are handled by two hold-type push-button switches.

[0134] In some executable embodiments, the brake triggering module 02 includes a brake interface 201 for connecting the brake of the electric actuator and a second auxiliary contact 202 of the first contactor.

[0135] The brake interface 201 is connected in series with the second auxiliary contact 202 of the first contactor.

[0136] The brake trigger module 02 and the control terminal interface module 01 are electrically connected through the first contactor.

[0137] After the coil 1201 of the first contactor is energized, it controls the second auxiliary contact 202 of the first contactor to close, and the brake trigger module 02 is energized.

[0138] The control terminal interface module 01 sends a signal to energize the coil 1201 of the first contactor.

[0139] Specifically, after the first contactor coil 1201 is energized, the second auxiliary contact 202 also closes. The closure of the second auxiliary contact 202 allows current to flow from the brake trigger module 02 through the brake interface 201 to the brake device, thus energizing the brake device. After the brake device is energized, the opening and closing of the brake can be controlled, thereby controlling the stopping and starting of the power end.

[0140] In some executable embodiments, an external power supply module 04 is also included.

[0141] External power module 04 includes: main switch 401.

[0142] The control terminal interface module 01 includes: a first rectifier circuit 103.

[0143] The brake trigger module 02 includes a second rectifier circuit 203.

[0144] The second rectifier circuit 203 is located between the main switch 401 and the brake trigger module 02; the main switch 401 is electrically connected to the brake trigger module 02 through the second rectifier circuit 203.

[0145] The first rectifier circuit 103 is connected to the main switch 401; the main switch 401 is electrically connected to the control terminal interface module 01 through the first rectifier circuit 103.

[0146] External power module 04 is used to connect to an external power source to provide power support for the offline debugging instrument. Main switch 401 is used to control the power supply of the offline debugging instrument; first rectifier circuit 103 is used to replace the power provided by external power module 04 with the voltage power required by control terminal interface module 01; second rectifier circuit 203 is used to replace the power provided by external power module 04 with the voltage power required by brake trigger module 02.

[0147] Specifically, the second rectifier circuit 203 is located between the main switch 401 and the brake trigger module 02. This means that the current first passes through the main switch 401 and then powers the brake trigger module 02 through the second rectifier circuit 203. The first rectifier circuit 103 is directly connected to the main switch 401, and the current powers the control terminal interface module 01 through the main switch 401 and the first rectifier circuit 103.

[0148] The main switch 401 allows the operator to quickly disconnect the power supply when needed, improving system safety. Two independent rectifier circuits provide the required voltages to the control interface module 01 and the brake trigger module 02, respectively, increasing testing flexibility. A single power input terminal can meet the different voltage requirements of multiple modules.

[0149] In some executable embodiments, the external power module 04 further includes an external power interface 402. One end of the external power interface 402 is connected to an external power source; the other end is connected to one end of the main switch 401. The external power interface 402 connects the power from the external power source to the main switch 401.

[0150] Specifically, the external power interface 402 obtains power from an external power source and then connects to one end of the main switch 401, ensuring that the power from the external power source can be further distributed to other parts of the electric actuator offline debugging instrument through the main switch 401, and providing power to the brake device and power end of the electric actuator.

[0151] In one executable embodiment, such as Figure 9 As shown, the offline debugging instrument for electric actuators includes a control terminal interface module 01, a brake trigger module 02, a mechanism action module 03, and an external power supply module 04.

[0152] The control terminal interface module 01 includes a control terminal interface circuit 101, a motor brake control circuit 102, and a first rectifier circuit 103.

[0153] The control terminal interface circuit 101 includes a coil 1101 of a first relay, a control terminal interface 1102, a coil 1103 of a second relay, a power-off reset button 1104, a limit selection coil 1105, an open limit contact 1106, a closed limit contact 1107, and an energized action hold button switch 1108.

[0154] The coil 1103 of the second relay and the power-off reset hold button 1104 belong to the power-off reset circuit, and the two are connected in series. The coil 1101 of the first relay, the control terminal interface 1102, the limit selection coil 1105, the open limit contact 1106, the closed limit contact 1107, and the energized action hold button switch 1108 belong to the energized circuit.

[0155] The limit selection coil 1105, the open limit contact 1106, and the close limit contact 1107 constitute a limit selection switch. The limit selection switch also includes a control board T01 for controlling the limit selection coil 1105.

[0156] The motor brake control circuit 102 includes a coil 1201 of a first contactor, a first auxiliary contact 1202 of the first contactor, a first auxiliary contact 1203 of the first relay, a first auxiliary contact 1204 of the second relay, a second auxiliary contact 1205 of the first relay, and a coil 1206 of the second contactor.

[0157] The coil 1201 of the first contactor, the first auxiliary contact 1202 of the first contactor, the first auxiliary contact 1203 of the first relay, and the first auxiliary contact 1204 of the second relay belong to the brake control circuit. The second auxiliary contact 1205 of the first relay and the coil 1206 of the second contactor belong to the motor control circuit.

[0158] The coil 1101 of the first relay is electrically connected to the first auxiliary contact 1203 and the second auxiliary contact 1205 of the first relay. When the coil 1101 of the first relay is energized, the first auxiliary contact 1203 and the second auxiliary contact 1205 of the first relay are closed.

[0159] The coil 1103 of the second relay is electrically connected to the first auxiliary contact 1204 of the second relay. When the coil 1103 of the second relay is energized, the first auxiliary contact 1204 of the second relay is open. Specifically, the first auxiliary contact 1204 of the second relay is a normally closed auxiliary contact.

[0160] The brake triggering module 02 includes a brake interface 201, a second auxiliary contact 202 of the first contactor, and a second rectifier circuit 203.

[0161] The coil 1201 of the first contactor is electrically connected to the second auxiliary contact 202 of the first contactor and the first auxiliary contact 1202 of the first contactor.

[0162] When the coil 1201 of the first contactor is energized, the second auxiliary contact 202 and the first auxiliary contact 1202 of the first contactor are closed.

[0163] The mechanism action module 03 includes the first auxiliary contact 301 of the second contactor, the action interface 302, and the action switch group 303.

[0164] The coil 1206 of the second contactor is electrically connected to the first auxiliary contact 301 of the second contactor. When the coil 1206 of the second contactor is energized, the first auxiliary contact 301 of the second contactor closes.

[0165] The action switch group 303 also includes a switch control circuit T02 and an action contact 3301.

[0166] Switch control circuit T02, such as Figure 10 and Figure 11 As shown.

[0167] like Figure 10 As shown, the switch control circuit T02 includes a slide switch, a coil K1 of the first steering relay, and a coil K2 of the second steering relay.

[0168] like Figure 11 As shown, T02 also includes a normally open contact NO1 of the first steering relay, a normally closed contact NC2 of the first steering relay, a normally open contact NO2 of the second steering relay, a normally closed contact NC1 of the second steering relay, a coil 1 of the first steering control relay, and a coil 2 of the second steering control relay.

[0169] The normally open contact NO1 of the first steering relay, the normally closed contact NC1 of the second steering relay, and the coil 1 of the first steering control relay are connected in series to form the first steering circuit; the normally open contact NO2 of the second steering relay, the normally closed contact NC2 of the first steering relay, and the coil 2 of the second steering control relay are connected in series to form the second steering circuit; the first steering circuit and the second steering circuit are connected in parallel. The normally open contact NO1 of the first steering relay and the normally open contact NO2 of the second steering relay are connected to an external power supply or an internal power supply.

[0170] When the coil 1 of the first steering control relay is energized, contact 1 in the action contact 3301 closes, which means that the power end runs in a clockwise direction; when the coil 2 of the second steering control relay is energized, contact 2 in the action contact 3301 closes, which means that the power end runs in a counterclockwise direction.

[0171] The external power module 04 includes a main switch 401 and an external power interface 402.

[0172] This utility model also includes a first closed external switch 001JS, a second closed external switch 002JS, and a third closed external switch 003JS. The first closed external switch 001JS, the second closed external switch 002JS, and the third closed external switch 003JS are used to quickly cut off the power supply in case of emergency stop or overload protection during testing, so as to prevent equipment damage or ensure personnel safety.

[0173] Specifically, the first closed external switch 001JS is located between the main switch 401 and the first rectifier circuit 103. The second closed external switch 002JS is located between the main switch 401 and the second rectifier circuit 203. The third closed external switch 003JS is located between the second rectifier circuit 203 and the brake interface 201.

[0174] In one embodiment, the fully open and fully closed adjustment of the electric actuator is achieved by closing the energized retainable push-button switch 1108. Specifically, when the energized retainable push-button switch 1108 is closed, the coil 1101 of the first relay is energized, thereby closing the first auxiliary contact 1203 and the second auxiliary contact 1205 of the first relay. After the first auxiliary contact 1203 and the second auxiliary contact 1205 of the first relay are closed, the circuit containing the coils 1201 and 1206 of the first contactor is completed, and the coils 1201 and 1206 of the first contactor are energized.

[0175] After the coils 1201 and 1206 of the first contactor are energized, the first auxiliary contact 301 of the second contactor and the second auxiliary contact 202 of the first contactor close. When the second closed external switch 002JS and the third closed external switch 003JS are closed, the brake trigger module 02 is turned on, and current flows into the brake device through the brake interface 201. When the first auxiliary contact 301 of the second contactor is closed, the mechanism action module 03 is turned on, and current flows into the power end through the action interface 302.

[0176] Two AC power supplies are drawn from the external power module 04 through the first rectifier circuit 103 and the second rectifier circuit 203 to the brake trigger module 02 and the control terminal interface module 01, so that the input voltage of the brake device is 205VDC.

[0177] The system enables the adjustment of the energized and de-energized switches under both forward-opening and reverse-closing conditions, as well as forward-closing and reverse-opening conditions, through the energized circuit, the de-energized reset circuit, and the operating switch group 303.

[0178] Specifically, when T02 selects option 1 (clockwise), the positive sequence power is connected to the power circuit, and the actuator rotates clockwise; when T02 selects option 2 (reverse), the reverse sequence power is connected to the power circuit, and the actuator rotates counterclockwise.

[0179] Select T01 1 to connect the internal opening limit switch of the electric head to the circuit; select T01 2 to connect the internal closing limit switch of the electric head to the circuit.

[0180] Forward Open, Reverse Close: T02 selects 1, T01 selects 1; when button 1108 is closed, the normally closed contact of 1106 closes, relay 1101 is energized, normally open contacts 1202 and 1205 of relay 1101 close, contactors 1201 and 1206 are energized, normally open contact 1203 of contactor 1201 closes to self-lock the 1201 circuit, normally open contact 202 of contactor 1201 closes to connect the power supply to the holding brake device, normally open contact 301 of contactor 1206 closes to send power to the motor. Because TO2 has been selected for forward rotation, positive sequence power is connected to the motor, and the actuator rotates clockwise. Because T01 has been selected for the open limit, when the actuator rotates clockwise to the open position, normally closed contact 1106 opens, and relay 1101 loses its function. When the actuator is powered on, the normally open contacts 1202 and 1205 of relay 1101 open, contactor 1206 is de-energized, and the normally open contact 301 of contactor 1206 opens, causing the actuator to stop operating, indicating that it has reached the open position. Since contactor 1201 is self-locked, the brake device remains energized, and the actuator remains in the open position, realizing the forward opening function. When it is necessary to close the actuator, button 1104 is closed, relay 1103 is energized, the normally closed contact 1204 of relay 1103 opens, contactor 1201 is de-energized, the normally open contact 202 of contactor 1201 opens, and the brake device is de-energized. Since the actuator compresses the internal spring to store energy during the electric forward opening, the internal spring is released when the brake device is de-energized, and the actuator moves in the opposite direction of opening under the action of the spring, thus realizing the reverse closing function.

[0181] Forward-closed, reverse-open: Select 1 for T02 and 2 for T01, and the rest are the same as forward-open, reverse-closed.

[0182] The third closed external switch 003JS can simulate the effect of the actuator's action on the mechanism's operation during the switching process when the brake is energized or de-energized.
