Description
Technical Field
The invention belongs to the technical field of high-temperature gas cooled reactors, and particularly relates to a device and a method for a baffle plate test of a helium circulator of a high-temperature gas cooled reactor.
Background
Helium is used as a coolant of a primary loop of the high-temperature gas cooled reactor, and is driven to circularly flow in the reactor and the steam generator through the helium circulator, so that heat of the primary loop is carried out. The primary helium fan is provided with a fan baffle, so that the inlet baffle of the primary helium fan needs to be closed when the reactor is in an emergency shutdown, the natural circulation of a primary loop medium is blocked, and the phenomenon that the overheat helium of the reactor core is in contact with the pressure container for heat exchange to cause overtemperature damage to the primary loop pressure container is avoided.
Compared with a common valve, the function and the structure of the inlet baffle of the helium circulator of the demonstration project of the high-temperature gas cooled reactor have a plurality of unique parts, and the inlet baffle is positioned in a primary loop, so that a mechanical limit switch cannot be installed, and the on-off state of the baffle can be fed back only through an electric limit switch of an electric device. The inlet baffle of the main helium fan is safety related equipment, and in order to ensure that the baffle of the main helium fan is reliably closed after shutdown, the baffle of the main helium fan is provided with two active and passive redundant closing means with different principles. The passive closing function of the fan baffle plate must be fully verified during the debugging period of the main helium fan, but the fan baffle plate is installed in a loop, so that the problem that the fan baffle plate cannot be visually monitored in opening degree due to the fact that the fan baffle plate cannot stably work for a long time under the environmental condition of the loop of the high-temperature gas cooled reactor due to the fact that reliable mechanical limiting is not available at present. During the passive function test, the electric device of the fan baffle does not act, and the auxiliary judgment of indirectly judging the opening degree of the fan baffle through the limit switch of the electric device cannot be realized.
Because the baffle of the main helium fan is positioned in a loop, a power cable and a control signal cable of an electric device of the main helium fan all need to pass through an electric penetration piece of the loop. Therefore, if the blower baffle is installed or the wiring is wrong after the primary circuit electrical penetration piece and the top cover of the helium circulator are installed, the pressure boundary of the primary circuit needs to be opened again, the end connection of the primary circuit electrical penetration piece is damaged, the blower baffle can be subjected to fault treatment, and the workload is very large. In order to ensure the accuracy of the cable termination of the fan baffle on site, the fan baffle needs to be tested and verified before a loop electric penetrating piece is installed. However, because the primary circuit electrical penetration piece is not installed, a temporary device needs to be developed to perform a fan baffle test before installing the cylinder and the primary circuit electrical penetration piece, and a set of test method needs to be designed by matching with the test device.

Furthermore, a connecting interface electrically connected with the helium circulator baffle is arranged on the control device. That is to say, accessible connection interface is experimental device access main helium fan baffle for the action to the baffle is experimental, can realize the effective control to main helium fan baffle, and can satisfy the experimental multi-functional demand of main helium fan baffle.

Furthermore, an aviation plug matched with the cable of the main helium fan is arranged at the tail end of a control cable of the test device, the test device is connected with the control cable of the baffle of the main helium fan, and a test of the baffle at the inlet of the main helium fan is carried out, wherein the internal circuit structure of the test device is shown in fig. 2, a control loop of the baffle test device of the main helium fan comprises a local switch valve, a remote switch valve and a valve switch indication loop, and the control loop has the functions of power indication, current indication, remote and local switching, active and passive switching, fan baffle opening, fan baffle stopping, fan baffle closing and fan baffle operating to a passive position, and is provided with a control panel shown in fig. 1 according to the control loop.
Based on the structure of the device, the working principle is as follows:
after the temporary testing device of the baffle of the helium circulator is connected with the baffle electric device and the field power supply end, the temporary testing device gets power from one phase supplied by the baffle electric device. When the test device is in the on-site control mode, the opening, stopping and closing operations of the helium circulator baffle can be realized through a valve opening button, an emergency stop piece (a middle stop button) and a valve closing button on the test device; if the active and passive switching piece is arranged at the active position, the main helium fan baffle cannot be stopped in the valve opening or closing process until the valve opening limit switch or the valve closing limit switch of the baffle electric device acts; if the passive and active components are arranged at the passive position, the valve opening or closing process of the baffle is started and then delayed for 7 seconds to stop. When the temporary testing device is arranged in a remote control mode, the opening and closing operation of the baffle of the helium circulator can be realized through the DCS, and the action mode of active and passive positions is the same as the local control mode. In the opening or closing process of the baffle of the helium circulator, the auxiliary judgment of the action of the baffle can be carried out through the current indication change on the temporary device.

And S230, switching the baffle switch piece between the opening position and the closing position to enable the baffle of the helium circulator to be in different positions, namely, when the baffle is switched to the active position or the passive position, switching the baffle switch piece to the opening position or the closing position.
S240, indicating the current value of the action process when the helium circulator baffle is at different positions by using the current indicating piece, enabling the fan baffle to be at different positions based on the different switching processes, enabling the fan baffle to correspondingly act when the helium circulator baffle reaches different positions, correspondingly generating the current value, and judging the action of the fan baffle by displaying the current value through the current indicating piece.

And fourthly, when the local and remote switching piece 110 is switched to the local position or the remote position, the active and passive switching piece 120 is switched to the passive position, the baffle switching piece is switched to the closed position, and after a preset time period is delayed, the baffle of the helium circulator stops at the passive position.
It should be noted that the active and passive switching elements and the shutter opening/closing element perform the same operation when the active and passive positions are in the same remote position as the local control mode, that is, when the local position is in the local position or the remote position as the remote switching element.
Further, the test method further comprises: in the working process of the baffle of the main helium fan, when the current value indicated by the current indicator is greater than the preset current value, the action of the baffle of the main helium fan is stopped.
