The silencing high voltage switch comprises a pair of switch electric poles [1] and a ring switch piece [2]. The two switch electric poles [1] are arranged face to face. An insulating air gap is arranged between the two switch electric poles [1]. The ring switch piece [2] is arranged in the air gap. The switch electric poles [1] and the ring switch piece [2] are fixedly connected as an integral body through an insulator. The silencing high voltage switch is characterized in that the insulator is an insulating casing [3]. The air gap is coated as an enclosed space [4] by the insulating casing [3]. The utility model improves the existing high voltage switch. The switch electric poles and the ring switch piece are sealed in the insulating casing. Thus, the noise is decreased when switching the switch. The good silencing effect can be obtained. The silencing high voltage switch is more suitable for medical appliances.
Description
Technical field
The utility model relates to a kind of high-voltage switch gear, is specifically related to the noise reduction high-voltage switch gear that uses on a kind of Medical Devices, such as the high-voltage switch gear that uses on the extra chock wave lithotriptor.
Background technology
In recent years, medicine equipment and Medical Devices development are rapid, and various therapy apparatuses emerge in an endless stream, and ultrasonic therapy apparatus, shock wave stone crusher or the like have occurred.Shock wave stone crusher is that the shock wave that utilizes electrion to produce focuses on the calculus of smashing afterwards in the patient body by the reflection basin, thereby reaches therapeutic purposes.Because the employed voltage of this equipment is about 12000 volts, and need frequent switch in the work, so one of this Medical Devices vitals is exactly a high-voltage switch gear.Existing high-voltage switch gear be on the insulating support with screw fit on a pair of high-voltage switch gear electrode, between this is to switch electrode, be provided with certain air gap, play insulating effect with this air gap, a ring switch tongue is set at the middle part of this air gap.Its operation principle is: when logical when going up high pressure on two switch electrodes, isolated because of the air of two interpolars, this two switch electrode is not conducting, when leading to high-tension electricity on the ring switch tongue, the air breakdown of two interpolars can be made two switch electrode conductings.Find that in actual use existing high-voltage switch gear has following deficiency: 1, use in hospital owing to this equipment, because of the air gap of switch is an open type, noise is bigger during break-make work, can destroy the quiet environment of hospital, has influence on patient's rest and doctor's operate as normal; 2, the axial concentricity between existing high-voltage switch gear two electrodes guarantees by screw thread, because the error of screw thread can cause the concentric locating of two switch electrodes accurate inadequately, thereby has influence on the performance of high-voltage switch gear; 3, installation, maintenance inconvenience, the staff who needs certain experience just can be seated.4, volume is bigger.
For overcoming above deficiency, the utility model improves existing high-voltage switch gear, designs the high-voltage switch gear that a kind of noiselessness, switch electrode location is accurate, volume is little.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of noise reduction high-voltage switch gear, comprise a pair of switches electrode and a ring switch tongue, pair of switches electrode surface opposite is provided with, be provided with insulative air gap between two switch electrodes, the ring switch tongue is arranged in this air gap, and switch electrode and ring switch tongue all are fixedly connected into integral body by an insulator, this insulator is an insulation crust, and insulation crust is surrounded as confined space with the air gap.
The related content and the change interpretation of technique scheme are as follows:
1, in the technique scheme, shape and relative distance by switch electrode and ring switch tongue on the inner chamber of described insulation crust are provided with location notch, and switch electrode and ring switch tongue all adopt the location notch location.Insulation crust can form with the nylon one.
2, in the technique scheme, described insulation crust is made of last cover and following cover, and last cover and following the cover among both have at least one inboard to be provided with cavity, after upper and lower cover is involutory, become integral body by bolt, its inner formation confined space.
3, in the technique scheme, more accurate in order to locate, can concavo-convex location structure be set at last cover and following cover apposition position.
The utility model operation principle is: leading to high-tension electricity on two switch electrodes, because of having insulative air gap between two switch electrodes, can not form current path between two switch electrodes, therefore at this moment high-voltage switch gear is obstructed; When leading to high-voltage pulse on the ring switch tongue, high-tension electricity can make the air breakdown between two switch electrodes between two switch electrodes and form path, high-voltage switch gear conducting at this moment.Therefore, only need to control the high electric field pulse that is added on the ring switch tongue, the i.e. break-make of may command high-voltage switch gear.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, since air gap of the present utility model be enclosed in the insulation crust, thereby the noise that produces when having reduced discharge in the air gap has greatly reached good erasure effect, is applicable to Medical Devices more.
2, because the utility model comes position-sensing switch electrode and ring switch tongue with location notch, guaranteed the concentricity and the relative distance of two switch electrodes, locate more accurately, be difficult for the generation error, made the high-voltage switch gear performance better.
3, same because the utility model comes position-sensing switch electrode and ring switch tongue with location notch, install and keep in repair convenient, general personnel also can assemble, and locating accuracy is guaranteed.
4, owing to one packaged type of the present utility model, more compact structure, volume is littler.
