Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the application schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail: the present embodiment is to implement under prerequisite in technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1: the present embodiment comprise flange raise seat 1, flange 2, two flanged gate valves 3,4 and dielectric barrier 5.A described flange rising seat material is copper, and the seat that raises is cylindrical, has the through hole of laterally zygomorphic diameter 20mm in a length direction centre position that raises, and on two holes, is separately installed with flanged gate valve; A flange rising seat one end, side is provided with flange, and opposite side is provided with dielectric barrier.A flange rising seat one end is welded with flange installation screw.The through-hole diameter 20mm that rising seat length direction centre position is offered.Described flange material is alloy aluminum, and external diameter is 295mm, and periphery is evenly distributed with 8 screws, and screw center is distributed on the circle that diameter is 270mm.Can be according to the installation requirement processing of sensor with fixation of sensor 8 on flange.Two described flanged gate valves are brass flange gate valve (DN25).Described dielectric barrier 5 materials are high density polyethylene, are installed on the seat other end that raises, in order to isolated transformer oil, simultaneously less on the impact of superfrequency sensor performance
In the present embodiment, this device is arranged on transformer tank by dielectric-slab, and O type circle sealing for dielectric-slab and transformer 9 tank wall hand hole junctions prevents that transformer oil from entering to be seeped in flange rising seat.
In the present embodiment, two flanged gate valves seal with O type circle with the flange junction of the seat upper and lower side that raises, and prevent leakage of oil.
In the present embodiment, sensor to be measured is fixed on flange, easy disassembly.
In the present embodiment, for analog sensor is placed in the situation of transformer inside, while starting testing sensor, first closed oil-out, opens pouring orifice 6, from pouring orifice 6, injects the transformer oil of same models, and is full of raise seat inner chamber, afterwards a closed pouring orifice; After test finishes, open oil-out 7, closed oil-out after the transformer oil in the seat inner chamber that raises flows out.
As shown in Figure 2: the device of the present embodiment is installed on the hand hole place of transformer 9 tank walls, in order to test superfrequency sensor.
In the present embodiment, the controlled shelf depreciation shelf depreciation situation that is virtually reality like reality of the inner generation of transformer, by signal access oscillograph observation signal on sensor.
In the present embodiment, different superfrequency sensors can be received to the local discharge signal of synchronization same type simultaneously, and compare its quality.
The advantage of the present embodiment:
1. can test easily and reliably the performance of partial discharge of transformer built-in ultrahigh frequency sensor;
2. by opening and closing pouring orifice and oil-out, analog sensor immerses transformer oil condition easily;
Structure is small and exquisite, with low cost, easy to process.
