Description
Technical Field
The invention relates to the field of intelligent devices of power equipment, in particular to a switch cabinet handcart one-key sequential control switching operation device.
Background
The one-key sequential control mode of the switching operation of the transformer substation can effectively improve operation efficiency, realize remodelling and automation of the switching operation of the transformer substation, and automatically complete state conversion of the transformer equipment. The one-key sequential control improves the response speed, improves the working efficiency of power transformation operation and maintenance, reduces the operation and maintenance cost and reduces the risk accident time of weak power grid operation. However, many substation devices are manually operated and do not have one-key sequential control automation conditions, which requires modification of the devices in the substation. The automatic transformation of the switch cabinet handcart can be divided into two types, one is that a driving operation motor is added in the switch cabinet to drive the switch cabinet handcart to move, and the other is that an automatic operation device is added outside the switch cabinet to drive the switch cabinet handcart to move.
The intelligent substation or the intelligent substation switch cabinet handcart is provided with a driving operation motor inside during factory manufacturing, so that automatic control is realized. However, if the driving operation motor is added in the switch cabinet, the conventional transformer substation switch cabinet handcart is transformed, whether the problems of the type, the size, the structure, the space, the position, the wiring and the like of the operation motor are satisfied or not needs to be considered. During transformation, the transformed line is required to be subjected to power failure treatment, one transformer substation is usually provided with more than ten or more than ten switch cabinets, and power failure of different degrees causes less power supply quantity and reduced economic benefit. When the driving circuit or the operation motor fails, the circuit can only be processed by power failure, and the problems of inconvenient maintenance, reduced power supply and the like are caused.
The automatic operation device is additionally arranged outside the switch cabinet, and the automatic operation device can be divided into two types, namely, a simple driving operation motor module device is additionally arranged outside the switch cabinet, and a switch cabinet handcart with a driving device correspondingly fixed is realized. However, this method requires more than ten or more than ten automation module devices, which results in waste of resources. The other type is to realize that one automatic operation device corresponds to all switch cabinet handcarts in a transformer substation through a universal automatic operation device. For example, chinese patent CN208015455U discloses a switching operation robot for operating all switch cabinet trolleys in a station. Although it can realize automatic switching operation, the most difficult problem of one-key sequential control transformation is how to realize double confirmation of the equipment position, namely, it cannot identify the position state of the equipment before and after operation. The problems of safety, misoperation prevention and the like of one-key sequential control of equipment are not solved, and the automatic operation function is simply realized. For example, the switching operation robot cannot identify the actual position of the switch, and if abnormal conditions such as switch closing or non-pulling are encountered, the problems of risk accidents of the loaded hand-shake switch handcart and the like are caused.

The switch cabinet handcart one-key sequential control switching operation device is used for shaking in or out the switch cabinet handcart to enable the switch cabinet handcart to move from a starting position to a target position, and the adopted operation method is that the intelligent measurement and control device 3 sends out a shaking in and out control signal to control the handcart shaking in and out mechanism to drive the switch cabinet handcart to move from the starting position to the target position, and the method is as follows:
the switch cabinet handcart one-key sequential control switching operation device is charged in real time at the position of the fixed charging pile, and the intelligent measurement and control device 3 is connected with the background machine in real time through the data transmission interface 15. The five-prevention logic of switching operation is loaded to the intelligent measurement and control device 3, and the switching operation device can perform the shaking-in or shaking-out operation on the switch cabinet handcart only when the switch position and the grounding disconnecting link position are in the separated positions, namely, the condition that the switch cabinet handcart is shifted is that the switch and the grounding disconnecting link in the switch cabinet are in the separated positions, as shown in an attached drawing 4. The switch split corresponds to the background machine switch position K1, the switch telemetry value K2, the switch cabinet primary graph switch position K3 and the switch actual position K4, and the grounding switch split corresponds to the background machine grounding switch position K5, the switch cabinet primary graph grounding switch position K6 and the auxiliary sensor grounding switch position K7.
The switch position judgment realizes double confirmation by utilizing the switch remote signaling deflection and the remote measurement value which are transmitted to the intelligent measurement and control device 3 by the background machine in real time and the actual position of the switch shot by the camera 12, and the remote signaling indication position of the switch of the last wiring diagram of the secondary cabinet shot by the camera 12 can be added for further safety consideration for judgment. The ground disconnecting link position judgment is transmitted to the ground disconnecting link remote signaling position of the intelligent measurement and control device 3 in real time through a background machine, and the detected ground disconnecting link state information transmitted by the newly added auxiliary sensor is subjected to double confirmation of the ground disconnecting link position, so that the remote signaling indication position of the ground disconnecting link of the last wiring diagram of the camera 12 shooting switch secondary cabinet can be additionally considered for further safety.
The station information of each switch cabinet switching operation device is loaded to the intelligent measurement and control device 3, after the switching operation device receives a one-key sequential control operation instruction issued by a background machine, the switch cabinet is walked from a fixed charging pile position to a switch cabinet designated station position ready for operation under the control of the intelligent measurement and control device 3, the brake fixing device 10 is controlled by the intelligent measurement and control device 3 to fix the switching operation device firmly, then the camera 12 shoots the double-name number of the ready operation switch cabinet, and the accuracy of the operated equipment is confirmed again.
The switching operation device can display the current issued instruction on the background machine in the process of executing the instruction issued by the background machine, and when the instruction related to the operation process is issued, the system can not execute the instruction, and the corresponding prompt slogan is provided, so that the switching of the remote control and the near control of the switch can be omitted, and a soft switch can be added for further safety consideration to perform the switching of the remote control and the near control of the switch.
When the switching operation device is normally operated, the intelligent measurement and control device 3 sends out a first type of shaking-in and shaking-out control signal capable of controlling the handcart shaking-in and shaking-out mechanism to drive the switch cabinet handcart to move by first power, if the switch cabinet handcart cannot be driven to move by the first power in the process that the handcart shaking-in and shaking-out mechanism drives the switch cabinet handcart to move by the first power, the intelligent measurement and control device 3 sends out a second type of shaking-in and shaking-out control signal capable of controlling the handcart shaking-in and shaking-out mechanism to drive the switch cabinet handcart to move by second power (the second power is larger than the first power), and the handcart shaking-in and shaking-out mechanism drives the switch cabinet handcart to move by the second power. If the condition that the switch cabinet handcart moves in place is satisfied: the camera 12 shoots that the handcart deflection information displayed by the last wiring diagram of the switch secondary cabinet is changed to the target state position, and the first power or the second power can not drive the switch cabinet handcart to move, and then the intelligent measurement and control device 3 judges that the switch cabinet handcart has moved to the target position and controls the handcart to shake into and out of the mechanism to cut off. The initial position of the switch cabinet handcart is the working position, the target position is the test position, or the initial position of the switch cabinet handcart is the test position, and the target position is the working position.
For further safety, the intelligent measurement and control device 3 is provided with a number of turns n required for the handcart to swing into and out of the mechanism during the process of moving the handcart of the switch cabinet from the initial position to the target position. After the handcart is shifted to the target state position by the last wiring diagram of the switch secondary cabinet, the intelligent measurement and control device 3 detects whether the rotation number of the handcart shaking-in and shaking-out mechanism is within n-1 to n+1 circles and judges whether the handcart of the switch cabinet moves in place. And after the operation of the switching operation device is finished, automatically returning to the fixed charging pile position for charging, and transmitting data to the background machine and checking the data of the background machine.
When an abnormal event is encountered in the operation process, the switching operation device automatically returns to the fixed charging pile position for charging after returning the switch cabinet handcart to the initial position, and then sends out alarm information to prompt operation and maintenance personnel to go to the site to be changed into manual operation. The rollback manner of a specific exception event is as follows, but is not limited to the exception events listed below.
The switching operation device is driven by first power to swing the switching handcart from an initial position to any position in a stroke of a target position, when remote signaling does not reach the target state position and the handcart cannot swing, the intelligent measurement and control device 3 controls the operation motor 2 to output second power, and if the switching handcart swings normally, the switching handcart is continuously operated to the target position; if the switch handcart cannot be rocked by operating the operating motor 2 under the drive of the second power, the intelligent measurement and control device 3 controls the operating motor 2 to output a third power (the third power is larger than the second power) to execute a backspacing instruction, and the switch handcart is rolled back to the initial position, namely if the handcart shift information displayed by the last wiring diagram of the switch secondary handcart is not changed to the target state position and neither the first power nor the second power can drive the switch handcart to move, the intelligent measurement and control device 3 sends a third type of shaking-in shaking-out control signal capable of controlling the handcart shaking-in shaking-out mechanism to drive the switch handcart to move by the third power, and the handcart shaking-in shaking-out mechanism drives the switch handcart to move reversely by the third power and returns to the initial position. And after the operation is finished, the switching operation device automatically returns to the fixed charging pile position for charging.
