Abstract
The utility model relates to an indoor interchange high voltage isolator, including driving shaft, connecting rod, pull rod and the moving contact of mutual linkage, the static contact is fixed on the frame through last positioning seat to cooperate with the one end of moving contact, the other end of moving contact articulates on well positioning seat, and the fuse concatenates below it. The utility model overcomes other high-voltage electrical apparatus products exist among ordinary indoor interchange high voltage isolator and the power system structure complicacy, reliability, security defect not good enough have easy and simple to handle, good heat dissipation, reliability, security are strong, the advantage that performance index is high, if use 0.5A's voltage transformer protection fuse, its rated short-circuit protection capacity reaches 50 KA.
Description
The utility model relates to a kind of indoor ac high-voltage isolating switch.
At present, be applied to the high voltage electric appliance of 10KV electric power system major loop, comprise isolating switch, on-load switch and circuit breaker etc., they all have crucial effect in electric power system.But in some respects as the voltage transformer cabinet, no matter the control of its voltage transformer and protection (electric current 0.5-2A) use any of above-mentioned high voltage electric appliance, all have some deficiency, as complex structure, cost height, reliability, fail safe is not good enough or the like.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby a kind of simple in structure, reliability is high, security performance is good indoor ac high-voltage isolating switch is provided.
The utility model comprises framework, driving shaft, connecting rod, pull bar, moving contact and fixed contact, driving shaft, connecting rod, pull bar and moving contact link mutually, fixed contact is fixed on the framework by last positioning seat, and match with an end of moving contact, on the positioning seat, its below was connected in series fuse during the other end of moving contact was hinged on.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises framework 1, driving shaft 2, connecting rod 3, pull bar 4, moving contact 5 and fixed contact 6, driving shaft 2, connecting rod 3, pull bar 4 and moving contact 5 link mutually, i.e. an end Joint of driving shaft 2 and connecting rod 3, and the two ends of pull bar 4 are hinged with pull bar 3 and moving contact 5 respectively.Fixed contact 6 is fixed on the framework 1 by last positioning seat 7, and matches with an end of moving contact 5, and the other end of moving contact 5 is hinged on the middle positioning seat 8.The below serial connection fuse 9 of moving contact 5, the two ends of fuse 9 are inlaid in the lower carriage 10,11, and on the positioning seat 8, lower carriage 11 was fixed on down on the positioning seat 12 during upper bracket 10 was fixed on.As unusual electricity consumption situation takes place, fuse 9 automatic disconnections have guaranteed the safe handling of high voltage electric appliance under user mode.
The utility model makes indoor ac high-voltage isolating switch be enhanced to the adaptability of environment by above-mentioned concrete setting, and the performance index height, and as using the voltage transformer protection fuse of 0.5A, specified short-circuit protection capacity reaches 50KA.Have simple in structure, good reliability, advantage that security performance is good.
