Description

The utility model relates to electrical engineering and can be used to enter electrical conductors into the work area. (Used in particular in a sealed chamber (CC)).
One of the important and crucial operations during explosive experiments is the supply of electrical signals to various measuring devices located inside the GC, as well as the output of information from them outside the chamber to the measuring complexes during the preparation and conduct of experiments, and the chamber must not be leak-tight in place transition settings neither during nor after experiments. To implement these requirements, it is necessary to install in the camera a special transition designed to work in multi-channel electrical circuits of direct and alternating current, which allows to obtain more information from one device.
A device is known (p. RF 2192680 publ. 10.11.2002) the current lead of electrical communications to ensure a tight passage of wires through the walls and overlap of the sealed zones of nuclear power plants, consisting of a housing with hermetically sealed conductors in it, installed in the embedded channel and sealed in it with welding.
The disadvantage of this device is the complexity of the design, the impossibility of quick installation and dismantling, as well as the use of welding during installation.
A device is known (p. RF 2322719 publ. 04/20/2008) high-voltage transition for introducing electrical conductors into the working area, consisting of a housing with hermetically installed insulators and a conductor, hermetically installed in the chamber wall using o-rings.
The disadvantage of this device is the presence of only one channel for transmitting an electrical impulse
The task of developing a utility model is to create a sealed shock-resistant transition operating in installations under high pressure up to P = 14.7 · 10 6 Pa (150 kgf / cm 2 ), withstanding shock loads of up to 500 g and a test voltage of at least 500 V and having two and more channels. It is also necessary to ensure ease of installation of the high-voltage transition into a sealed chamber.
The problem is solved in that in the transition to the working area through the metal wall of the protective structure, in particular an airtight chamber containing a hermetically sealed cylindrical body in the wall with a hermetically sealed insulating element in which at least one electrical conductor is located, characterized in that on the ends of the case with the help of a threaded connection, pipes are installed, on the ends of which, in turn, with the help of union nuts, sockets with electrical leads are secured from the external it and the inner side, the number of which corresponds to the number of electrical conductors passing through the insulating element of the housing, with each conductor connected to the corresponding outlet of the outlet also by an electrical conductor. The insulating element is made of caprolon A, which has high mechanical and electrical insulation properties and is installed in the housing hermetically using sealing rings. The transition housing is made of 35KhGSA steel, which ensures its high strength under impact loads up to 500 g. Electrical conductors are made of silver-plated brass, this ensures a minimum transient electrical resistance, leading to minimal losses in the transmission of an electrical impulse. Electrical conductors are sealed inside the insulating element using o-rings. On the landing surface of the housing there are grooves for installing o-rings in them, which provide sealing of the high-voltage transition in the wall of the sealed chamber. The presence of o-rings ensures the tightness of the transition.
In FIG. The transition design is shown.
The transition consists of a housing 1, in which a gasket 2 is installed, insulating elements 3, 4 with O-rings 5, pressed against the housing by nuts 6, 7. Inside the insulating elements are electrical conductors 8 (in this case 10 pieces), sealed by rings 9. On the pipe 10 is screwed on from both ends of the housing to which sockets 12 are fastened with union nuts 11. Electrical installation by conductors 13 is made from the electrical conductors 8 to the contacts of the sockets 12. The cavities with mounting A and B are filled with a compound. The ends of the transition are closed by caps 14. On the transition housing there are grooves for installing the sealing rings 15.
Assembly is as follows:
A gasket 2 is installed in the housing 1. In the insulating element 3 with sealing rings pre-mounted on it 5, electrical conductors 8 are installed with the sealing rings pre-mounted on them 9 and pressed by insulating sleeves 4. The insulating element 3 is inserted into the housing 1 and pressed by the nut 6, s of the other end, each electrical conductor 8 and the insulating sleeve 4 are fixed with a nut 7. From both ends of the housing, the conductors 13 are electrically mounted to the electrical conductors 8 and installed branch pipes 10. Then conduct electrical installation of conductors 13 to sockets 12 and they are installed with nuts 11 on branch pipes 10. The internal cavities of branch pipes A, B with electrical installation are filled with a compound. The transition sockets are protected by caps 14. O-rings 15 are installed in the grooves on the landing surface of the housing.
This design solution has several advantages:
- the transition has 10 channels for transmitting electrical signals, allowing it to be used in multi-channel electrical circuits of direct and alternating current, to receive more information from one device.
- standard connectors are used - RM plugs
- the transition design is simple and technologically advanced (does not require complex mechanical operations);
- rubber o-rings make it easy and reliable to ensure tightness;
- when installing rubber seals in the metal case of the transition, it is not necessary to take into account the temperature expansion coefficients of the materials.
