Embodiment Construction
[0036] like Figure 1~4 As shown, a wire and cable high-voltage cabin penetration test equipment includes a bracket 2, a pressure cabin 1 fixed on the bracket 2, a hydraulic system 4 connected to the pressure cabin 1, and a high-pressure pump 5 connected to the hydraulic system 4. The bracket 2 includes a base 21 and a V-shaped positioning groove disposed on the base 21 . The barrel 11 rests in the V-shaped positioning groove, and the barrel 11 is fixed on the base 21 through the U-shaped hoop 22 . In order to facilitate the operation of wires and cables 9 passing through the cabin at both ends, the pressure cabin 1 is generally placed horizontally.
[0037] The pressure-resistant cabin 1 includes a hollow cylinder 11, at least one guide pipe 16 arranged in the cylinder 11, and a sealing device for sealing the end face of the cylinder 11. The sealing device is provided with a 16 is butted with a through hole 17, and a sealing member is provided at the outer opening of the th...

The invention discloses wire cable high-pressure cabin through testing equipment which comprises a bracket, a pressure resistant cabin, a hydraulic system and a high-pressure pump, wherein the pressure resistant cabin is fixed on the bracket; the hydraulic system is connected with the pressure resistant cabin; the high-pressure pump is connected with the hydraulic system; the pressure resistant cabin comprises a hollow cylinder, at least one guide tube arranged inside the cylinder and a sealing device for sealing an end surface of the cylinder; through holes in butt joint with the guide tubesare formed in the sealing device; sealing parts are arranged at outer portholes of the through holes; a water inlet hole and exhaust holes are formed in the cylinder; a sealing valve for controlling the exhaust holes to be opened and closed is arranged on the cylinder; over-voltage holes communicated with the hollow cavity of the cylinder are formed in the guide tubes; the hydraulic system is connected with the sealing valve and the water inlet hole. By adopting the equipment disclosed by the invention, wire cables can be rapidly and accurately fed through a cabin and rapidly and convenientlysealed and fixed, and thus cabin through testing can be rapidly and conveniently carried out.
Description
technical field [0001] The invention belongs to electric wire and cable test equipment, in particular to a high-voltage cabin penetration test equipment for electric wire and cable. Background technique [0002] With the development of the field of science and technology, equipment in the deep sea or deep wells has put forward pressure-resistant technical requirements for communication optical cables and cables, and a series of pressure-resistant cable products such as well logging optical cables and submarine cables have been derived, and these products must be used before they are put into use. After withstand voltage test. The test content includes the compressive strength and the failure length of the wire and cable after failure under a certain pressure. A common practice is to cut a small section of wire and cable, place this small section of wire and cable in a pressure vessel, and then apply pressure to test its compressive strength. [0003] There are following di...
