Description

Double type valve reactor

Technical field

The utility model relates to electric equipment, especially relates to the structural design of valve reactor.

Background technology

Valve reactor belongs to key components and parts in high voltage direct current transmission converter valve.Valve reactor can be divided into core type structure and shell type structure by core structure pattern, and wherein shell type structure reactor is that the coil design of reactor is become cylinder mode, is fixed on coil by iron core by fastener, in coil is wrapped in by iron core.There is following shortcoming in traditional shell type structure design: the electromagnetic force that one reactor in use produces due to electric current can cause core vibration, and long vibration can cause the phenomenon such as silicon steel sheet discrete piece, the reduction of iron core mechanical strength; The components over time such as its two iron cores, coil in atmosphere exposed, surface easily produces the phenomenons such as burn into gets rusty; Its three shell type structure assembling mode mechanical strength is low, easily causes coil insulation to damage.

Utility model content

The purpose of this utility model is for the structure of valve reactor provides the valve reactor that a kind of mechanical strength is high, temperature rise is even, noise is low, long service life, fire protecting performance are good, easy installation and reliable.

In order to reach above-mentioned requirements, the utility model is realized by following scheme: it includes spiral coil, there are two C shaped iron cores the upper and lower side of coil is involutory, and by iron core fastener, two C shaped iron cores are fixed on above coil, the two ends of coil are stretched out outside iron core, and be connected with the connection of busbar for external electrical, composition shell type core valve reactor, it is characterized in that outside coil, be coated with the shell made with high flame retardant insulating material, embedding polyurethane elastomer material in space between the coil and iron core of valve reactor and between iron core and shell, make iron core, coil, shell pours into as a whole, shell is provided with jockey, be fixed together bottom chlamydate for band valve reactor with mounting base.

Described jockey on the external peripheral surface of shell, is provided with connecting hole or on the inner circumferential surface of shell, is provided with connecting hole or is provided with connecting hole in the bottom of shell, base plate is provided with the fixing hole corresponding with each connecting hole, and is connected and fixed through bolt, nut fastener.

According to the double type valve reactor that such scheme manufactures, reactor design is become the structure of double type, by the material package such as iron core, coil of reactor in a set of shells, iron core, coil, shell is made to become as a whole by the method for embedding polyurethane elastomer material.The high flame retardant design of shell wherein can improve insulation, the fire protecting performance of reactor greatly, can have employed Duct design, add the cool cycles of air to valve reactor at the middle part of shell.Polyurethane material has excellent heat conduction and resistant to elevated temperatures performance, by the conductive force of polyurethane, the temperature of the inner each position of reactor is tended to balance, reduces the phenomenon of local overheating.Polyurethane material itself has very high elasticity and shear strength, by can increase the mechanical strength of valve reactor to coil and the filling between iron core and shell etc.Cushioning effect is played to vibration in use, and can effectively the material such as iron core, coil and air be isolated, avoid the parts long term exposure of valve reactor burn into brought in atmosphere and the phenomenon such as to get rusty.Therefore to have mechanical strength high, easy for installation for the reactor of this structure, vibrates little, the advantages such as noise is low, long service life.
