Embodiment 1
[0017] See Figure 1 to 3 As shown, a smart electrical energy meter durability test device comprising a closed chamber, a heating unit (not shown) and a humidification unit in the test housing 1 (not shown) and humidification units are provided in the test housing 1 (not shown) and humidification units in the test housing 1 Not shown in the figure, the Type clip 2 is provided in the test housing 1; at least three line holes 3 are opened at the bottom of the test case 1, and the wire hole 3 is formed. Work wire 4.
[0018] Further, a accessory housing 5 is provided below the test housing 11, and a winding mechanism is provided in the accessory housing 5, the analog working wire 4 is wound on the winding mechanism.
[0019] Further, the winding mechanism includes a bracket 6 fixed to the access casing 5, and the bracket 6 is rotated and connected to the roll shaft 7, and at least one end of the winding shaft 7 is provided with a roll spring 8 that keeps tensioning. The simulation wor...
Embodiment 2
[0024] See Figure 1 to 3 As shown, a smart energy meter durability test device according to the present embodiment, is further provided in the basis of the first embodiment, and the winding mechanism further includes a ratchet that is set to the coaxial wire around the reel 7 9, the ratchet 9 is rotated synchronously with the winding roller 7, and the aclayed casing 5 is rotated and the pressure plate 10 is connected, and a plurality of ratchet 11 in the wheel groove embedded in the ratchet 9 is provided on the pressure plate 10.
[0025] Further, a connecting rod 12 is provided between the adjacent two pressure plates 10.
[0026] In the present embodiment, when the analog working wire 4 is in a connection state, the analog working wire 4 remains tightened, and it is easy to fall off from the smart electrical energy form, and there is a test hidden danger. This scheme can rotate the pressure plate 10 and pressed on the ratchet 9, causing the ratchet 11 inserted into the wheel slo...
Embodiment 3
[0029] See Figure 1 to 3 As shown, an intelligent energy meter durability test device according to the first embodiment, and is further arranged, and the line hole 3 is in an analog working wire 4 in an emulated working conductor 4 based on Examples 1 and 2. The protective cover 13.
[0030] In the present embodiment, the outer wall of the analog working wire 4 is protected by the addition of the protective sleeve 13, and damage is avoided by friction of the inner wall of the line hole 3.
[0031] The intelligent energy meter durability test apparatus according to the present invention, increasing the internal temperature humidity to simulate the harsh environment of the test, and thereby turned on the smart power table by each corresponding analog working wire, which makes it normal in the test housing, reacted The effect of durability testing; and the intelligent energy meter maintains the normal operation of the simulated working wire without falling off, the test is stable, re...
