Abstract
A magnetic-resonance starting up and shutdown system is disclosed. An external alternating current power supply is successively connected with an isolation transformer and a stabilized voltage supply through a first alternating current contactor. The stabilized voltage supply is successively connected with a first time delay relay and a second alternating current contactor and then is connected with a spectrometer cabinet. The stabilized voltage supply is successively connected with a second time delay relay and a third alternating current contactor and then is connected with a gradient cabinet. The external alternating current power supply is connected with the transformer. The transformer, an emergency button, a startup button switch, a shutdown button switch and the relays form a loop. The relays control on and off of the first alternating current contactor. Through ingenious cooperation of the relays and the alternating current contactors, the switch of an operation panel can be used to start and close the whole system and many tedious steps and maloperation which can be brought by the steps are omitted so that the whole system is simple and humanized.
Description
Technical field
The utility model relates to nuclear magnetic resonance image instrument field, especially switching system.
Background technology
After three stabilized voltage power supply voltage stabilizings, feed distribution box and carry out operations such as step-down isolation shunting, the supply power voltage of spectrometer cabinet and gradient cabinet is provided by distribution box again.The spectrometer cabinet is made up of industrial computer, spectrometer, control box, radio-frequency (RF) power amplification, is controlled the power supply supply of each device by the rack battery main switch.The gradient cabinet is made up of three tunnel gradient modules, gradient power supply, by the power supply of rack battery main switch control gradient modules.The power supply of three cabinets has separately independently switch control, and open and close has order requirement successively mutually, and opens when closing switch and need open the rack shutter, and the start step process is loaded down with trivial details.
Above-mentioned magnetic resonance distribution system is unit combination, and is separate and influence each other.This makes the start step must open the power switch of each rack respectively, and switch is opened according to a definite sequence.This brings great inconvenience to the operator, is easy to generate faulty operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of magnetic resonance power on/off system, controlled energising or the outage of each rack by a switch, successively in order, the energising of each rack has a time difference for the power supply of each rack, avoids moment total road electric current excessive.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of magnetic resonance power on/off system, and external ac power source is connected with described isolating transformer, stabilized voltage power supply successively by first A.C. contactor; Described stabilized voltage power supply is successively by being connected with the spectrometer cabinet behind first time-delay relay, second A.C. contactor; Described stabilized voltage power supply is successively by being connected with the gradient cabinet behind second time-delay relay, the 3rd A.C. contactor; Described external communication is connected with transformer, and described transformer and danger button, start key switch, shutdown key switch and relay form the loop, and described relay is controlled the described first A.C. contactor break-make.After the switch start of pushing button, the external communication electricity through the transformer step-down after, the transformer secondary output coil is powered to control relay, the power on/off by control relay and then control the break-make of first A.C. contactor is powered to subsequent conditioning circuit; And the scram button of control panel, key switch be installed on the loop of control relay, comes the break-make of break-make first A.C. contactor with break-make control relay voltage; Isolating transformer and stabilized voltage power supply internal circuit have possessed delay circuit, need not to add time-delay and connect, and electric current was given the power supply of spectrometer cabinet through after the stabilized voltage power supply in 3 seconds by the time-delay of first time-delay relay; Gave the power supply of gradient cabinet in 5 seconds by the time-delay of second time-delay relay simultaneously, between two unit 2 seconds time difference power supply is arranged, this has just finished use console switch control whole system order opening process.The shutdown switch that only need push button just can be finished the outage of whole system, and is easy and simple to handle.
As improvement, described danger button and key switch are located on the same control box, make operation with simple and convenient.
The beneficial effect that the utility model compared with prior art brings is:
Cooperate with the ingenious of A.C. contactor by relay, can use the switch of guidance panel to the open and close of whole system, omitted quite a lot of trivial step and the misoperation that may bring, make whole system simpler, more humane.
Description of drawings
Fig. 1 is the utility model electrical schematic.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of magnetic resonance power on/off system, external ac power source is connected with described isolating transformer 8, stabilized voltage power supply 9 successively by first A.C. contactor 6.Described stabilized voltage power supply 9 is connected with spectrometer cabinet 10 by first time-delay relay 7, second A.C. contactor, 12 backs successively; Described stabilized voltage power supply 9 is connected with gradient cabinet 11 by second time-delay relay 13, the 3rd A.C. contactor 14 backs successively.Described external communication electricity is connected with relay 1 by transformer 5, shutdown key switch 4, danger button 3, start key switch 2 backs successively, described danger button 3, start key switch 2 and shutdown key switch 4 are located on the same control panel, make operation with simple and convenient.Described first A.C. contactor, 6 break-makes of described relay 1 control.
The utility model operation principle: after pressing 2 starts of start key switch, after 5 step-downs of external communication electricity process transformer, transformer 5 secondary coils give control relay 1 power supply, and the power on/off by control relay 1 and then control the break-make of first A.C. contactor 6 is powered to subsequent conditioning circuit; And the scram button on the control box 15, key switch be installed on the loop of control relay 1, comes the break-make of break-make first A.C. contactor 6 with break-make control relay 1 voltage; Isolating transformer 8 and stabilized voltage power supply 9 internal circuits have possessed delay circuit, need not to add time-delay and connect, and electric current gave the spectrometer cabinet 10 power supplies through after the stabilized voltage power supply 9 in 3 seconds by 7 time-delays of first time-delay relay; Gave the gradient cabinet 11 power supplies in 5 seconds by 13 time-delays of second time-delay relay simultaneously, between two unit 2 seconds time difference power supply is arranged, this has just finished use console switch control whole system order opening process.Shutdown only need be pressed shutdown key switch 4, just can finish the outage of whole system, and is easy and simple to handle.
The utility model cooperates with the ingenious of A.C. contactor by relay 1, can use the switch of guidance panel to the open and close of whole system, has omitted quite a lot of trivial step and the misoperation that may bring, and makes whole system simpler, and is more humane.
