Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The invention provides a sequentially controllable energy storage device for shutdown circuit breakers, which includes at least two circuit breakers, all of which can be connected in parallel and simultaneously receive control signals sent remotely. Each circuit breaker is equipped with a control circuit for time-controlled opening and energy storage of the circuit breaker. The control circuits of these circuit breakers receive control signals from the remote end, and then control the opening, Energy storage and closing are used to control the energy storage sequence of different circuit breakers, which is used to realize the purpose of controlling multiple circuit breakers when the power of the control power supply is limited. Taking a group of 4 circuit breakers as an example, the time relay is used to control the energy stor...

Abstract

A sequence-controllable energy storage device and method are provided. For each circuit breaker, a second time relay II, a third time relay III and a fourth time relay IV are switched on through an action of a first time relay I after a remote opening pulse signal is received by the first time relay I; a second control loop is connected to the second time relay II, the third time relay III and the fourth time relay IV which are in parallel connection; the inside of the third time relay III is provided with opening time; a normally open contact of the third time relay III is closed to perform opening in the opening time, and is disconnected in other time; the inside of the fourth time relay IV is provided with energy storage time; the inside of the second time relay II is provided with closing time; and the closing time and the energy storage time do not overlap. Opening and energy storage signals of shutdown circuit breakers are separated, and different pulse contacts of the time relays are utilized to control opening and energy storage respectively, thus reducing power consumption of a power supply and ensuring system safety.

Description

technical field [0001] The invention relates to the control of a nuclear power reactor shutdown circuit breaker, in particular to a sequential energy storage control device and an energy storage method for a shutdown circuit breaker. Background technique [0002] Nuclear power plant and nuclear submarine protection subsystems constantly monitor important process parameters that are directly related to the mechanical limits of the equipment, as well as parameters that directly affect the heat transfer capability of the reactor. A reactor scram is a protective function performed when a parameter is expected to exceed a safe value. When the coil of the control rod drive mechanism is de-energized, the control rods fall to the core by gravity to shut down the reactor. [0003] The reactor shutdown circuit breaker is used to trigger a reactor shutdown. The reactor shutdown circuit breaker is connected to the power supplied by the motor-generator set and the rod control system, w...
