Summary of the invention
The purpose of this utility model provides a kind of control rod drive mechanisms (CRD) power-supply system with quick startup and fan-out capability.
In order to achieve the above object, the technical solution of the utility model has provided a kind of control rod drive mechanisms (CRD) power-supply system of quick startup, comprise at least two units, be connected with synchronous device between every adjacent two units, the structure of each unit is identical, it is characterized in that: each unit comprises power source bus, power source bus connects closing by hand input circuit breaker, closing by hand input circuit breaker connects motor, motor connects flywheel, generator operation under flywheel drives, engine connects automatic closing output circuit breaker, is connected with automatic voltage regulator on generator.
The control rod drive mechanisms (CRD) power-supply system of a kind of quick startup that the utility model provides has the ability of quick startup and output, adopt this device after, can reach desired purpose in conjunction with corresponding software again.
Description of drawings
Fig. 1 is the electrical schematic diagram of control rod drive mechanisms (CRD) power-supply system.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the control rod drive mechanisms (CRD) power-supply system of quick startup has in the present embodiment comprised two units, i.e. a unit 2 and No. two unit 2 ＇.Between two units, be connected with a synchronous device 9.The structure of two units is identical, wherein, unit 2 comprises that unit input circuit breaker 3, unit input circuit breaker 3 one ends connect a unit power source bus 1, the other end connects a unit motor 4, a unit motor 4 drags a unit flywheel 5 and drives set generator 6 operations, No. one set generator 6 connects unit output circuit breaker 7 No. one, is connected with a unit automatic voltage regulator 8 on a set generator 6.
No. two unit 2 ＇ comprise that No. two unit input circuit breaker 3 ＇, No. two unit input circuit breaker 3 ＇ one ends connect No. two unit power source bus 1 ＇, the other end connects No. two unit motor 4 ＇, No. two unit motor 4 ＇ drag No. two unit flywheel 5 ＇ and drive No. two set generator 6 ＇ operations, No. two set generator 6 ＇ connect unit output circuit breaker 7 ＇ No. two, are connected with No. two unit automatic voltage regulator 8 ＇ on No. two set generator 6 ＇.
The course of work of the present utility model is:
Step 1, a unit motor start-up
After the unit 2 of control rod drive mechanisms (CRD) power-supply system is ready, manually a unit input circuit breaker 3 is closed a floodgate, a unit motor 4 gets electric back rotating speed from a unit power source bus 1 and rises, and drags 6 operations of set generator of unit flywheel 5 drives.
After a unit motor 4 operated in rated condition, No. one unit automatic voltage regulator 8 put into operation automatically, and exciting current is started from scratch and grown steadily, and set generator 6 is built steadily and pressed and set end voltage is started from scratch and grown steadily.
Step 3, a set generator are incorporated into the power networks
When stable and unit satisfies rated condition when set generator 6 terminal voltage, unit output circuit breaker 7 automatic closings of a set generator 6, a unit 2 starts to be finished.
Step 4, No. two unit motor start-ups
After No. two unit 2 ＇ of control rod drive mechanisms (CRD) power-supply system are ready, manually No. two unit input circuit breaker 3 ＇ are closed a floodgate, No. two unit motor 4 ＇ get electric back rotating speed from No. two unit power source bus 1 ＇ and rise, and drag No. two set generator 6 ＇ operations of No. two unit flywheel 5 ＇ drives.
Step 5, No. two set generator excitations drop into
In the startup accelerator of No. two unit motor 4 ＇ rotating speeds risings, No. two unit automatic voltage regulator 8 ＇ put into operation in good time automatically, and exciting current is started from scratch and grown steadily, and No. two set generator 6 ＇ build pressure steadily.
Step 6, the same period
In the process of No. two set generator 6 ＇ end frequencies rising, synchronous device 9 detects the relations such as output voltage, frequency and phase place of units 2 and No. two unit 2 ＇ automatically, whether allows the same period at the appointed time, if not, then execution in step 7, if then execution in step 8.
The automatic disjunction of No. two unit input circuit breaker 3 ＇, this moment, the inertia of No. two unit flywheel 5 ＇ still can keep No. two set generator 6 ＇ output in allowing range of operation, the back No. two units input of of short duration time-delay circuit breaker 3 ＇ close a floodgate automatically again, and execution in step 6 then.
After the same period, instruction was sent, No. two unit output circuit breaker 7 ＇ automatic closings, No. two unit starting is finished, and the control rod drive mechanisms (CRD) power-supply system successfully puts into operation.
