Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings of the description. The scope of protection claimed by the present invention is not limited to the scope described in the specific embodiments.

[0012] figure 1 It is a high-voltage dry-type welding test cabin's strong electric signal cable penetrating device. In order to make the front end 62 of the double-ended screw 6 pass through the bulkhead 1 and extend into the bulkhead 1, a perforation 12 can be opened on the bulkhead 1. . Through the threaded blind hole 11 provided on the outside of the bulkhead 1 and matched with the screw 2, it is arranged on the outside of the bulkhead 1 . This method is used in the closed space research ecological balance test, and the deficiency in the strong current penetration wall is that the whole device is located on the outside of the bulkhead 1, and no defensive measures are taken for the inside of the bulkhead 1; secondly, the bli...

Abstract

The invention relates to a sealed insulating material bulkhead-penetrating device for strong electricity which is indispensable for introducing the strong electricity into space with high tightness; a bulkhead-penetrating conductor is screwed in the wall of the sealed space in a threaded manner and fixed by an insulating seal spacer, an insulating hollow lead screw and a nut, and thereby tightness of the bulkhead-penetrating conductor and the bulkhead is improved; by using the spacers, gaskets and other materials, strong magnetic field generated by alternating current is reduced or weakened. The pressure of the silica gel seal spacer is increased by the insulating hollow lead screw and the insulating nut with threads. A binding post with large current and high performance is adopted to meet requirements on large current and low resistance. And two ends of the binding post are fixed by the combination of flat gaskets and nuts, and the strong magnetic field generated by the alternating current and the appearance of eddy current are reduced as much as possible; two sides of the bulkhead of the sealed space are basically symmetrically distributed, so that lever balance and screw pitch balance of the lead screw conductor are ensured, and tightness of connection of the bulkhead of the sealed space and the lead screw conductor is also ensured.

Description

technical field [0001] The invention is a strong electric airtight insulation wall-through device processed by high-precision airtight insulating materials, and is one of the components that connect the airtight space with the external strong current exchange. Security through-the-wall device. The invention is applicable to the transmission and conduction of direct current and alternating current of high voltage and strong current. Background technique [0002] In the current field of ecological improvement technology, confined space method is one of the most widely used technologies. With the wide application of the confined space method in research and application and the continuous innovation and advancement of technology, especially in recent decades, in the in-depth study of its biological mechanism and the balance of the entire system after adding human activities, the space confined method Great progress has been made in the theory and technology of biology and reac...
