Problems solved by technology

Since there is a gap between the outermost fastening bolt of the rear electrode and the inner non-metallic insulating sleeve, the fastening bolt cannot be installed horizontally with the cyclone chamber. In this way, it is necessary to manually lift the handle of the fastening bolt on the rear electrode with both hands and align it with the cyclone chamber. The cyclone chamber is installed horizontally, and the threaded handle for fastening the rear electrode of the high-power and large-sized tubular arc heater is very heavy, and the installation is very difficult, time-consuming and labor-intensive

Embodiment Construction

[0019] Such as figure 1 As shown, a quick installation device for the rear electrode of the tube arc heater includes a lock nut 1, a magnetic field coil 2, a rear electrode 3, a fastening bolt 4, a straight lead-in section 5 such as a fastening bolt, and a non-metallic insulating sleeve 6 and Cyclone chamber 7 constitutes. It is used to realize the rapid installation of the rear electrode of the thick tube arc heater.

[0020] The rear part of the tube arc is mainly composed of the rear electrode 3, the magnetic field coil 4, the locking bolt 4 and the non-metallic insulating sleeve 6. The rear electrode 3 of the tube arc heating equipment is disconnected from the front electrode in the cyclone chamber 7. Before the start of the tube arc operation, the rear electrode must be connected to the front electrode through the cyclone chamber through the arc wire. The joint is mainly pulled by the fastening bolt. The components are connected with the inner thread of the cyclone thro...

Abstract

The invention discloses a rear electrode rapid mounting device for a tube arc heater. The rear electrode rapid mounting device comprises a fastening bolt (4), a non-metallic insulating sleeve (6) anda cyclone chamber (7); the non-metallic insulating sleeve (6) is mounted outside a water cold sleeve of the tube arc heater; a magnetic field coil (2) and the fastening bolt (4) are mounted outside the non-metallic insulating sleeve (6), and an equal straight guiding-in section (5) is additionally arranged at the tail end of the fastening bolt (4); through the equal straight guiding-in section, shaking during connection of the fastening bolt with an inner cavity of the cyclone chamber is avoided; and the fastening bolt and the cyclone chamber are connected through threads, and through the fastening bolt, a front electrode and a rear electrode of the tube arc heater are connected.

Description

technical field [0001] The invention relates to a quick installation device for the rear electrode of a tube arc heater. Background technique [0002] When the aircraft flies at hypersonic speed, especially the re-entry missile, the aerodynamic heating phenomenon is extremely severe, and the aerodynamic thermal protection is related to the success or failure of its flight test. Therefore, before the flight test of hypersonic weapons, they must go through the assessment of ground simulation equipment. At present, the ground simulation test equipment is mainly based on the arc wind tunnel, and an important core equipment of the arc wind tunnel is the arc heater. The arc heating equipment that simulates high pressure, medium and low enthalpy is a tubular arc heater. Before the power supply operation, it is necessary to install the arc wire at the junction of the front and rear electrodes. The installation position of the arc wire is between the front and rear electrodes in the...
