Description
Technical Field
The invention relates to the field of intelligent devices of power equipment, in particular to a one-key sequential control switching operation device for a handcart of a switch cabinet.
Background
The one-key sequential control mode of the transformer substation switching operation can effectively improve the operation efficiency, realize the remote and automatic operation of the transformer substation switching operation, and automatically complete the state conversion of the transformer equipment. One-key sequential control improves the response speed, improves the operation and maintenance work efficiency of the power transformer, reduces the operation and maintenance cost and reduces the time of risk accidents caused by weak operation of the power grid. However, many substation devices are manually operated and do not have an automation condition of one-key sequential control, so that the devices in the substation need to be modified. The automatic transformation of the switch cabinet handcart can be divided into two types, one type is that a driving operation motor is added in the switch cabinet to drive the switch cabinet handcart to move, and the other type is that an automatic operation device is added outside the switch cabinet to drive the switch cabinet handcart to move.
The intelligent transformer substation or the intelligent transformer substation switch cabinet handcart is internally provided with a driving operation motor when being manufactured in a factory, so that automatic control is realized. However, if a driving operation motor is added in the switch cabinet in the conventional transformer substation switch cabinet handcart transformation, the problems of the model, the size, the structure, the space, the position, the wiring and the like of the operation motor need to be considered to meet the conditions. The transformed line needs to be subjected to power failure treatment during transformation, one transformer substation usually has dozens or dozens of switch cabinets, and power failure in different degrees causes less power supply and reduction of economic benefits. When a driving loop or an operating motor has faults, the line can be processed only by power failure, and the problems of inconvenience in maintenance, reduction in power supply and the like are caused.
The automatic operation device added outside the switch cabinet can be divided into two types, one type is that a simple driving operation motor module device is added outside the switch cabinet, and one driving device is correspondingly fixed to one switch cabinet handcart. However, this method requires tens or hundreds of additional automated module devices, resulting in waste of resources. The other type is that one automation operation device is corresponding to all switch cabinet hand trucks in one transformer substation through a universal automation operation device. For example, in chinese patent CN208015455U, a switching operation robot is used to operate all switch cabinet hand trucks in a station. Although it can realize automatic switching operation, the most difficult problem of one-key sequence control modification is how to realize the double confirmation of the equipment position, namely that it can not recognize the position state before and after the equipment operation. The problems of safety, misoperation prevention and the like of one-key sequential control of equipment are not solved, and only the automatic operation function is simply realized. For example, the switching operation robot cannot identify the actual position of the switch, and if the switch is stolen or not pulled, the risk accidents of the handcart with the load rocker switch can be caused.

The switch cabinet handcart one-key sequential control switching operation device is used for shaking in or out a switch cabinet handcart to enable the switch cabinet handcart to move from an initial 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 shaking out control signal to control the handcart shaking in and shaking out mechanism to drive the switch cabinet handcart to move from the initial position to the target position 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 switching operation five-prevention logic is loaded to the intelligent measurement and control device 3, and the switching operation device can only carry out the shaking-in or shaking-out operation on the switch cabinet handcart when the switch position and the grounding knife switch position are both in the separated position, namely the switch and the grounding knife switch in the switch cabinet are both in the separated position under the condition that the switch cabinet handcart is displaced, as shown in the attached figure 4. The switch separation position corresponds to a background machine switch position K1, a switch remote-measuring value K2, a switch cabinet primary graph switch position K3 and a switch actual position K4 separation position, and the grounding switch separation position corresponds to a background machine grounding switch position K5, a switch cabinet primary graph grounding switch position K6 and an auxiliary sensor grounding switch position K7 separation position.
Switch position is judged by utilizing the switch remote signaling deflection and remote measurement value 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 to realize double confirmation, and for further safety consideration, the remote signaling indicating position of the switch secondary cabinet last wiring diagram switch shot by the camera 12 can be judged. The grounding switch position judgment is transmitted to the grounding switch remote signaling position of the intelligent measurement and control device 3 in real time through the background machine, and the grounding switch state information detected by the newly-added auxiliary sensor is transmitted to carry out double confirmation of the grounding switch position, so that the remote signaling indicating position of the grounding switch of the last wiring diagram of the switch secondary cabinet can be shot by the camera 12 for further safety consideration to judge.
Station position 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 key sequential control operation instruction issued by a background machine, the switching operation device walks to a switch cabinet appointed station position to be operated from a fixed charging pile position under the control of the intelligent measurement and control device 3, the switching operation device is fixed and firm by controlling the brake fixing device 10 through the intelligent measurement and control device 3, then the camera 12 shoots double name numbers of the prepared operation switch cabinet, and the accuracy of the operated equipment is confirmed again.
The switching operation device can display the currently issued instruction on the background machine in the process of executing the instruction issued by the background machine, and the system can not execute when the instruction related to the operation process is issued, and has a corresponding prompt slogan, so that the switching of the switch between far and near control is not needed, and a soft switch can be added for the switching between far and near control of the switch for further safety consideration.
When the switching operation device normally operates, the intelligent measurement and control device 3 sends 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 with first power, and in the process that the handcart shaking-in and shaking-out mechanism drives the switch cabinet handcart to move with first power, if the switch cabinet handcart cannot be driven to move with first power, the intelligent measurement and control device 3 sends 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 with second power (the second power is greater than the first power), and the handcart shaking-in and shaking-out mechanism drives the switch cabinet handcart to move with the second power. If the conditions that the handcart of the switch cabinet is moved in place are met: the camera 12 shoots that the handcart displacement information displayed by the previous wiring diagram of the switch secondary cabinet is changed into a target state position, and the handcart of the switch cabinet cannot be driven to move by the first power or the second power, so that the intelligent measurement and control device 3 judges that the handcart of the switch cabinet has moved to the target position and controls the handcart to be shaken in and out of the mechanism to be powered off. The initial position of the switch cabinet handcart is the working position of the switch cabinet handcart, the target position of the switch cabinet handcart is the test position of the switch cabinet handcart, or the initial position of the switch cabinet handcart is the test position of the switch cabinet handcart, and the target position of the switch cabinet handcart is the working position of the switch cabinet handcart.
For further safety consideration, the intelligent measurement and control device 3 is internally loaded with the number n of turns of rotation required by the handcart shaking-in and shaking-out mechanism in the process of moving the handcart of the switch cabinet from the initial position to the target position. When the handcart is shifted to a target state position in a primary wiring diagram of a switch secondary cabinet, the intelligent measurement and control device 3 detects whether the number of turns of the handcart rolling-in and rolling-out mechanism is within n-1 to n +1 turns and judges whether the handcart of the switch cabinet is moved in place. And after the operation of the switching operation device is finished, the switching operation device automatically returns to the position of the fixed charging pile for charging, and transmits data to the background machine for checking with the data of the background machine.
When an abnormal event occurs in the operation process, the switching operation device automatically returns the handcart of the switch cabinet to the initial position to charge the handcart, and then sends out alarm information to prompt operation and maintenance personnel to change the handcart to the fixed charging pile position to manual operation. The specific exception events are rolled back as follows, but are not limited to the exception events listed below.
When the switching handcart is driven by the first power to shake from an initial position to any position in the stroke of a target position and the handcart is not remotely signaled to the target state position and cannot shake, the intelligent measurement and control device 3 controls the operation motor 2 to output second power, and if the switching handcart normally shakes, the handcart is continuously operated to the target position; if the operation motor 2 still cannot shake the switch handcart under the drive of the second power, the intelligent measurement and control device 3 controls the operation motor 2 to output a third power (the third power is larger than the second power) to execute a backspacing instruction, and backspacing the switch cabinet handcart to an initial position, namely if the handcart displacement information displayed on a previous wiring diagram of a switch secondary cabinet is not changed to a target state position and the switch cabinet handcart cannot be driven to move by the first power or the second power, the intelligent measurement and control device 3 sends a third 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 the third power, and the handcart shaking-in and shaking-out mechanism drives the switch cabinet handcart to reversely move 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.
