Description
Technical field
The utility model relates to medical instruments field, is mainly the medical isolating transformer of a kind of tape jam warning and localization of fault.
Background technology
General power supply grid adopts TN wiring system, is to using the earth as with reference to current potential, and the electric current in phase line can form loop over the ground by any uninsulated passage, and this is the basic reason of electric shock.Hospitals at Present is generally used TN-S wiring system; medical electrical equipment adopts neutral earthing (N) and the earthing of casing (PE) pattern; if but electric equipment electric leakage still carrys out work by fuse, air switch, earth leakage protective device in equipment; but their residual action current minimum current is 6-30mA, cannot meets special medical place (as operating room, conduit room, the chamber of reviving, DengⅡLei place, intensive care unit) and use.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of tape jam warning for the configuration of special medical place and the medical isolating transformer of localization of fault are provided, and safe and reliable power supply guarantee is provided.
The purpose of this utility model completes by following technical solution, it comprises medical isolating transformer, current transformer, medical insulating monitor, assessment of failure instrument, fault locating instrument, remote alarms guidance panel, described current transformer is connected with load circuit with isolating switch, between this current transformer and current transformer, adopt parallel way interconnection, current transformer is connected with medical insulating monitor, medical insulating monitor is connected with remote alarms guidance panel, medical insulating monitor is connected with assessment of failure instrument, assessment of failure instrument is connected with fault locating instrument, this medical insulating monitor and remote alarms guidance panel are powered by power source special.
As preferably, between described current transformer and electric power incoming line, be provided with medical isolating transformer.
The beneficial effects of the utility model are: in power supply unit inlet wire, accessed medical isolating transformer, any output phase line and ground all can not produce loop, link circuit can not produce because of equipment leakage the needs that the disconnection faults such as tripping operation affect operation and rescue, the security that has greatly improved current supply circuit; While having leaky in loop, remote alarms guidance panel can send sound and light alarm signal, and can on remote alarms guidance panel, indicate the position of fault loop according to the fault-signal that assessment of failure instrument and fault locating instrument detect, now need only the isolating switch on disengagement failure loop or the equipment plug breaking on loop and just can work, thereby operation and rescue work are normally carried out.
Accompanying drawing explanation
Fig. 1 is schematic block diagram of the present utility model.
Label in accompanying drawing is respectively: 1, medical isolating transformer; 2, current transformer; 3, medical insulating monitor; 4, remote alarms guidance panel; 5, assessment of failure instrument; 6, fault locating instrument; 7, power source special; 8, electric power incoming line; 21, isolating switch; 22, load circuit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in Figure 1, the utility model comprises medical isolating transformer 1, current transformer 2, medical insulating monitor 3, remote alarms guidance panel 4, described current transformer 2 is connected with load circuit 22 with isolating switch 21, 2 of this current transformer 2 and current transformers adopt parallel way interconnection, current transformer 2 is connected with medical insulating monitor 3, medical insulating monitor 3 is connected with remote alarms guidance panel 4, medical insulating monitor 3 is connected with assessment of failure instrument 5, assessment of failure instrument 5 is connected with fault locating instrument 6, this medical insulating monitor 3 and remote alarms guidance panel 4 are powered by power source special 7.8 of described current transformer 2 and electric power incoming lines are provided with medical isolating transformer 1.
The loop that the utility model is less than 10KVA by an operating room or single-phase power is as a power supply unit, electric power incoming line 8 ground in former electrical network after medical isolating transformer 1 isolation is no longer reference potential, any output line of medical isolating transformer 1 all can not directly form loop with ground, and this just provides the security of power supply.By the medical insulating monitor 3 and the remote alarms guidance panel 4 that send to after current transformer 2 collection signals on each loop in power supply unit after power source special 7 power supplies, and after fault-signal being detected, by assessment of failure instrument 5, sent the current transformer 2 in each loop of pulse signal detection, after the signal of fault locating instrument 6 collected current mutual inductors 2, show corresponding fault loop.
The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
