Chip electro-arc heater has Gao Han, high hot-fluid, long-time analog capability, is to carry out hypersonic aircraft and again
Enter one of important ground simulation testing equipment that recoverable capsule thermal protection is examined with thermal structural analysis, mainly by electro-arc heater sheet
The motivational guarantee such as body, jet pipe, control system and water supply, supply, power supply system is constituted.High pressure draught is heated through electro-arc heater,
Accelerated by nozzle expansion, form high temperature, high-speed jet, ablation certification test is carried out to the test specimen installed in nozzle exit.
The starting process of chip electro-arc heater is one of key link of its operation, is divided into two mistakes of scratch start and arcing
Journey：The first step, scratch start is exactly under high voltage electric field effect, encouraged by initial discharge (it is domestic it is general using wire short circuit,
Argon gas mode is ionized under high current melting or vacuum environment), trigger avalanche type ionisation effect, puncture chip electro-arc heater
The air between rear electrode and first order transition electrode piece in inner chamber, produces the short electric arc of one-level；Second step, arcing is exactly profit
The short electric arc of one-level is pulled into a long arc through electrode before and after chip electro-arc heater (up to several meters step by step with arcing circuit
It is long), using the direct current quick breaker closed in advance in the arcing circuit in parallel with each arcing in chip electric arc compression section level according to
Default program, delay disconnects successively draws the downstream arc root of the short electric arc of one-level by transition electrode piece to heater downstream successively
It is long until preceding electrode, during this, the physical parameter such as voltage, electric current, degree of ionization, air pressure, density of electric arc changes rapidly, and becomes
In stable.When in stable condition long arc is set up, then starting process is completed.
Arcing circuit is made up of the certain resistance of multistage direct current quick breaker series connection, and the resistance is with electric arc in main circuit
Into parallel connection, therefore when current flowing resistance, the voltage at resistance two ends is just applied to the corresponding compression of electro-arc heater simultaneously
Duan Shang, the voltage helps, by the air breakdown in correspondence compression section, electric arc to be pulled into next stage；When this grade of direct current is quick break
After device disconnects, the resistance will be bypassed, and be flowed through there is no electric current.
The concrete form of the starting resistance can have a variety of, predominantly van-type iron plate resistance and water-cooled steel pipe resistance.But
These resistance be present：1) cost is costly；2) structure is complex, is repaired after scaling loss, changes inconvenient；3) water
Cold type steel pipe electric resistance structure is not compact enough, space-consuming is big, also there is cooling water leakage and causes high electrical breakdown between resistance
It is dangerous；4) technical requirements are higher, and processing and manufacturing difficulty is larger.
The content of the invention
It is an object of the invention to provide a kind of steel wire resistance device available for chip electro-arc heater starting circuit, its
The starting arcing of chip electro-arc heater not only can be reliably and securely applied to, and the resistance can be with self manufacture, peace
Dress, method is easy, cheap, convenient maintenance and replacement, and connection combination is versatile and flexible, can overcome existing van-type iron plate resistance and water
The deficiency that cold type steel pipe resistance is present.
Technical scheme is as follows：A kind of steel wire resistance device of chip electro-arc heater starting circuit, the device
Including steel wire, metal splint, cleat insulator and support frame, wherein, the overall steel wire of required resistance value, according to steel wire resistance
Device installing space size and shape, are cut into some sections of sizeable steel wires, every steel wire is neat and spaced apartly
Horizontal parallel is arranged, and is fixedly connected with the end of adjacent two steel wires using metal splint, forms the overall electricity of head and the tail connection
Structure is hindered, meanwhile, some sections of steel wires that horizontal parallel is arranged are fixedly clamped using cleat insulator, layer of steel wire resistance junction is formed
Structure；If dried layer steel wire electric resistance structure be arranged on support frame in make every layer of steel wire electric resistance structure vertically be spaced one section away from
From；Every layer of steel wire electric resistance structure can use cable connection, and reserve cable connector as needed, form overall steel wire resistance dress
Put.
The middle part and two ends for some steel wires that described cleat insulator arranges horizontal parallel are gripped, and form one layer
Steel wire electric resistance structure.
Described cleat insulator is made of 3240 epoxy phenolic laminated glass fabric plates.
