Description
Affiliated technical field
The invention belongs to the water-cooled resistor field.
Background technology
Original water-cooled resistor, be directly to contact with resistor by cooling water to realize cooling, because cooling water directly contacts with resistor, cooling water is charged, in use there is very big potential safety hazard (particularly in high-tension circuit), and in some circuit, is unallowed; On the other hand, original water-cooled resistor adopts sealing ring is squeezed in realization location and sealing water in the seal groove, and this complex structure and assembling back are bulky, are not easy to be assembled into the water-cooled resistor of super large rank power.
Summary of the invention
Charged and be not easy to be assembled into the shortcoming of super large rank water-cooled resistor in order to overcome original water-cooled resistor cooling water, the present invention releases a kind of water-cooled resistor, can make between cooling water and the resistor and realize High-Voltage Insulation, removing seal groove simultaneously fits together numerous resistor cores compactly, simple in structure, volume greatly reduces.
The technical solution adopted for the present invention to solve the technical problems comprises 3 parts:
1, is parallel surface by 1 current divider box, 1 header tank, 2 sealing ring location-plates, 56 sealing rings, 28 contour both ends of the surface and dresses up matrix type dielectric water-cooled resistance unit with resistor core, screw rod, backstay, the nut block of axis normal.Current divider box has 1 water inlet, and 28 delivery ports, delivery port are distributed in by arranged on the sealing plane of current divider box, fix 1 sealing ring location-plate on this plane; Header tank has 28 water inlets, and 1 delivery port, water inlet are distributed in by arranged on the sealing plane of header tank, fix 1 sealing ring location-plate on this plane; In each hole of 2 sealing ring location-plates, keep flat 1 piece of sealing ring; Current divider box is down, the self seal plane up, header tank is last, self seal flats down, the middle resistor core of placing is fixed with screw rod and backstay, 2 sealing planes of current divider box and header tank should be in parastate.So both can realize simultaneously 56 seal positiver sealings, but reduced volume again.A plurality of matrix type dielectric water-cooled resistances unit can be assembled into the water-cooled resistor of super large rank power easily.
2, by keeping having enough differential water pressures to realize 28 tunnel water route flow equalizations that flow out from current divider box between current divider box water inlet and the delivery port, make cooling water flow through the cooling effect equilibrium that each resistor core produces.
3, resistor core adopts heat conduction, the good hollow porcelain tube of insulation, and the porcelain tube outer wall is with conducting film, the porcelain tube endoporus is through-flow moving cooling water.Owing to have tube wall to separate between cooling water and the conducting film just can to realize the double effects that cools off with High-Voltage Insulation.During work, the conducting film of porcelain tube outer wall bears power and produces heat, and the porcelain tube temperature is raise; The cooling water of porcelain tube endoporus and porcelain tube inwall carry out heat exchange, and heat is taken away, and the porcelain tube temperature is reduced.Porcelain tube was just under a certain temperature stabilization when the heat that heat that produces when conducting film and cooling water are taken away equated.If cooling water flow increases, thermal equilibrium temperature reduces, otherwise thermal equilibrium temperature raises.Thermal equilibrium temperature can be controlled in the safe working temperature scope of resistor by adjusting discharge.
The invention has the beneficial effects as follows, can realize the High-Voltage Insulation between cooling water and the resistor, and can make things convenient for the water-cooled resistor that is assembled into super large rank power compactly, have safe, simple and compact for structure, little characteristics take up room.
