Embodiment
As shown in Fig. 1-Fig. 4.A kind of high-temperature high-pressure high-power dummy load container, include the container 1 of the open top of cuboid shape, container 1 is made for high-temperature insulation material, container 1 is respectively arranged with dummy load electrode 2 along the two ends end face inwall of long side direction, resistance medium is contained with in container 1, and container 1 two ends arrange dummy load electrode 2 respectively with resistance medium contact, also include the metal clip 3 of multiple U-shaped, multiple metal clip 3 is installed in bottom container 1 respectively by respective U-shaped mouth, and multiple metal clip 3 equidistantly arranges along container 1 long side direction one word, each metal clip 3 connects a wire respectively, wire extends to container floor 13 along container side plate 11 inwall, with resistor main body electrical contact, this whole connected metal clip of wire in one plane.
High-temperature insulation material is polypropylene.
Container 1 is connected and composed by cuboid by two vessel side panels, 11, two container end panels, 12, container bottom panel 13, and joint seal between vessel side panel 11, container end panel 12, container bottom panel 13.
Dummy load electrode 2 is corrosion resistant plate, and two corrosion resistant plates are corresponding is respectively close to the two ends end face inwall setting of container 1 along long side direction.
Resistance medium is the liquid with certain conductivity, or has the powder of solid particles of certain conductivity, or has the solid-liquid composite material of certain conductivity.Resistance medium preferred water.
Metal clip 3 outer wall parcel polypropylene board.
The present invention is achieved in that the container of dummy load is processed by high-temperature insulation material polypropylene board, corrosion resistant plate electrode and metal clip and forms.Utilizing polypropylene board to form the open-top receptacle of a joint seal, is rectangle, the cross section approximately equal at two ends in the shape of corrosion resistant plate and container, and is vertically attached on this two ends cross section, as the both positive and negative polarity of dummy load.The size power parameter design according to actual needs of container, for the dummy load of MW class quasi-steady running, can be designed as the series connection of multiple identical container and uses.In order to prevent container deformation fracture when high temperature, adopt the metal clip of U-shaped by the tight-lipped subsides of U-shaped and be installed in outside of containers and arrange, its function is reinforced container, and the electric field of equalisation container inside.The shape of container and the layout of metal clip and quantity are that the composite factors such as resistivity, dummy load parameter and environment for use according to electrical conductivity materials determine.Resistor main body material can adopt liquid, also can be the powder of solid particles with certain conductivity, also can be solid-liquid composite material.
According to actual dummy load power and voltage parameter, mix resistivity of water, running time and evaporation of water amount, calculate the gross mass of mixing water needed for dummy load.Resistance value again required for dummy load calculates cross-sectional area and the length of container.The power parameter of dummy load is excessive, and many containers can be adopted to connect.Such as Chinese Academy of Sciences's plasma a dummy load being greater than 2MW/1 hour parameter, design use 20 dummy load containers series connection, single container is of a size of 3 meters × 1.2 meters × 0.8 meter.
In the present invention, first according to design size, cut out 5 pieces of polypropylene panels of container, 11, two the container end panels of two vessel side panels namely in Fig. 2,12, container bottom panel 13; Utilize mariages welding rod and base material that these sheet materials are welded into the open-top receptacle of joint seal; Process 2 pieces of corrosion resistant plates as dummy load electrode 2 according to the shape of container end panel 12, be placed on container 1 inner, be attached on two container end panels 12 respectively; The bottom interval 30cm of container 1 just clamps the metal clip 3 of a U-shaped; The body comprises metal of metal clip 3 is made, and outside parcel polypropylene board, gets rusty for waterproof.
If the overtension of load, dummy load container needs to isolate over the ground, specifically according to practical application and relevant GB determination insulating supporting parameter.
