Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0029] A maintenance tool for a Hall-type reversing switch instrument, which is designed in an integrated manner and mainly includes the following components: magnetic pole detection sensor device, control panel, speed-regulating motor, magnet, reversing switch, relay and output instruct.

[0030] The control panel includes speed controller, automatic controller, adjustable power supply and manual controller.

[0031] In the control panel, the automatic controller can control the speed regulating motor by controlling the speed controller, and control the reverse switch by controlling the adjustable power supply;

[0032] The manual controller can control the speed regulating motor by controlling the speed controller, and control the reversing switch by controlling the adjustable power supply.

[0033] The speed-regulating motor can control the magn...

Abstract

The invention belongs to the technical field of operation monitoring of nuclear power plants, and particularly relates to an overhauling tool of a Hall-type reversing switch instrument. The overhauling tool is designed in an integrated manner, and comprises a magnetic pole detection sensing device, a control panel, a speed regulating motor, magnetic steel, a reverse switch, a relay and an output indication; the control panel comprises a rotating speed controller, an automatic controller, an adjustable power supply and a manual controller; in the control panel, the automatic controller can control the speed regulating motor by controlling the rotating speed controller, and can control the reversing switch by controlling the adjustable power supply; and the manual controller can control therotating speed controller by controlling the rotating speed controller, and can control the reversing switch by controlling the adjustable power supply. The magnetic pole detection sensing device integrated in in the tool can perform magnetic pole identification, verification and polarity judgment on the magnetic steel of the instrument, so as to judge the magnetic properties and polarity of the magnetic steel of the instrument, quickly locate the installation direction of the magnetic steel, and to prevent the wrong installation direction of the magnetic steel onsite from leading to abnormalworking of the instrument.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant operation monitoring, and in particular relates to a maintenance tool for a Hall type reversing switch instrument. Background technique [0002] At present, the nuclear power plant widely adopts the reversing switch instrument of Hall principle. During the overhaul or mediation period of the nuclear power unit, the functional inspection of this type of instrument will be carried out, and the problems existing in the instrument will be found in time and corrective maintenance will be carried out to ensure that the instrument can meet the function of monitoring the rotating state of large rotating equipment such as circulating water pumps, so as to ensure that the unit is in the next stage. Safe and stable operation during a nuclear fuel cycle. [0003] In the actual maintenance process, the instrument has problems such as lack of guiding installation method, immature debugging method, ...
