Abstract
The utility model relates to a field distortion spark switch for an external knapper, which is composed of a main electrode, a trigger electrode, an insulator, an air extracting pump, wherein, an upper and a lower main electrodes are arranged on an insulating bush, the trigger electrode passes through central spaces of the main electrodes, and is fixed with a screw thread by a collet, a discharging tip of the trigger electrode is positioned between the upper and the lower main electrodes, a vent hole is arranged on the upper electrode, the air enters from the vent hole of the upper electrode when the air extracting pump pumps gas out from the lower collet, which causes the gas of the discharging gap of the upper and the lower electrodes to move continuously in order to ensure an insulativity and lengthen an operating life of the switch. The operating life of the field distortion spark switch can reach to 10 < 6 > times.
Description
The utility model relates to electric switch, particularly utilizes the strong distortion of gap electrical field under the trigger impulse and the spark switch of rapid conducting.
The core of extra chock wave lithotriptor is surge generator (an abbreviation shock wave source), main switch is its critical component, its effect is that charged pulse capacitor was discharged energy in the microsecond magnitude time to load (water space), to obtain the strong shock wave of submicrosecond pulsewidth.Main switch commonly used has three electrode switch, discharge tube, field distortion spark gap etc.Chinese patent CN85201717 utility model patent has disclosed a kind of field distortion spark gap, is made up of two main electrodes, a trigger electrode and three insulating sleeves, and this switch can make the discharge time delay less than 80 nanoseconds, and discharge time delay dispersiveness is less than 20 nanoseconds.This patent adopts the gases at high pressure that charge in the periodic replacement switch, with the desired dielectric strength in assurance gap, and the cleaning switch electrode, to obtain long service live (greater than 10
4Inferior).But this contact capacity big (60KV, 180KV), construction of switch is had relatively high expectations to sealing and intensity.
The purpose of this utility model be design a kind of can fast and stable discharge, long service life, field distortion spark gap simple in structure.
Formation of the present utility model is made up of main electrode, trigger electrode, insulator and aspiration pump.Main electrode comprises upper and lower electrode, and the hollow garden dish of flange is arranged in the middle of it is shaped as, and this upper and lower electrode is installed on the insulating sleeve, forms the main electrode assembly.Trigger very the Metallic rod that a centre has garden dish type discharge tip, there is screw thread at these Metallic rod two ends, there is a T shape air vent hole at the center of one end, one end has a location flange, trigger electrode passes the main electrode centre bore, one end is fixed on the following collets of bottom electrode, and the other end is fixed on the last collets of top electrode with nut.At this moment, the most advanced and sophisticated garden of trigger electrode dish is positioned in the middle of the main electrode.Following collets center has air vent hole to communicate with the T shape air vent hole of trigger electrode, and following collets also have one section tracheae to be connected with aspiration pump.On the dish of the garden of top electrode, be drilled with several (as four) apertures.
Illustrate that accompanying drawing is as follows:
Fig. 1 is the utility model extracorporeal lithotiptor field distortion spark gap schematic diagram.
Accompanying drawings embodiment is as follows:
(1) is top electrode among Fig. 1, and (2) are bottom electrode, and upper and lower electrode is installed on the insulating sleeve (3), the intermediate gaps that trigger electrode (4) passes upper and lower electrode (1,2).Fix with nut (7) and main electrode by last collets (5) and following collets (6), and form a whole, the discharge tip of trigger electrode during installation (4) should be in the centre position of upper and lower main electrode.Main electrode (1,2) available copper tungsten alloy and brass are made, and trigger electrode (4) available copper tungsten alloy and stainless steel are made, and insulating sleeve (3) and the available nylon 6 of collets (5,6) are made.Aspiration pump (8) is an electromagnetic pump.
Connect electromagnetic pump (8) at the middle air vent hole place of following collets (6) during the work of the utility model field distortion spark gap and bleed, on top electrode (1), have four apertures simultaneously.Air promptly enters and extracts out from the air vent hole of following collets (6) from aperture, makes the air in the inner whole space of insulating sleeve (3) be in flow regime.Can guarantee desired dielectric strength in gap and cleaning electrode surface between main electrode (1,2) like this, thereby prolong working life.
The utility model extracorporeal lithotiptor can reach 10 with the field distortion spark gap working life
6Inferior, switch is cleaned the cycle greater than 5 * 10
4Inferior/as once to clean.And the existing general life-span of the used discharge tube of stone crusher only is 10
4Inferior, the general life-span of three electrode switch and field distortion switch about 10
5Inferior, the switch scouring cycle is 10
4Inferior.
Claims (1)
1, a kind of main electrode that comprises, trigger electrode, the field distortion spark gap of insulator, it is characterized in that said main electrode is by last, bottom electrode is formed, the hollow garden dish that flange is arranged in the middle of it is shaped as, on being somebody's turn to do, thereby being installed in, bottom electrode forms the main electrode assembly on the insulating sleeve, triggering very, a centre has the Metallic rod that discharge tip is coiled in the garden, there is screw thread at these Metallic rod two ends, one end has a location flange, there is a T type air vent hole at the center of the other end, central space one end that trigger electrode can pass main electrode is fixed on the following collets of bottom electrode, and an end is fixed on nut on the last collets of top electrode, and following collets center has air vent hole to communicate with the T type air vent hole of trigger electrode, and have tracheae to link to each other with aspiration pump, on the dish of the garden of top electrode, be drilled with several apertures.
