Abstract
The utility model discloses an oil-immersed transformer liquid level measuring device which solves the problem that an oil leveler pipe of an existing measuring device can be easily blocked. The oil-immersed transformer liquid level measuring device is characterized in that transformer oil (12) and a transformer body (1) are arranged in a transformer box body (2), a measuring hole (5) is formed in a top cover of the transformer box body (2), a floating ball rod sleeve (10) is arranged on the measuring hole (5), a transparent protection sleeve (7) is connected to the top end of the floating ball rod sleeve (10), a top cover (8) is arranged at the top end of the protection sleeve (7), a floating ball (3) is arranged in the transformer oil (12), the floating ball (3) is connected with one end of a floating ball rod (4), the other end of the floating ball rod (4) sequentially penetrates through the measuring hole (5) and the floating ball rod sleeve (10) to be movably arranged in the protection sleeve (7), and scale marks (6) are arranged on the sleeve wall of the protection sleeve (7). The oil-immersed transformer liquid level measuring device is simple in structure and accurate in measurement, and ensures safe and stable operating of a transformer.
Description
Technical field
The utility model relates to a kind of liquid level proving installation, particularly a kind of oil-filled transformer liquid level proving installation.
Background technology
It is minimum that hermetically sealed oil-filled transformer is down to the moisture of transformer inside by vacuum oil technology, overflows up hill and dale to guarantee the bubble that transformer gas inside and " air horn " are located, and makes oil thoroughly soak into transformer-cabinet.In maintenance at ordinary times, the oil level that needs to pay close attention to transformer oil in real time changes, and in time charges and discharge transformer oil.Existing oil level measuring device is based on law of connected vessels mostly and carries out level gauging, oil ga(u)ge pipe and respirator latch up phenomenon occur through regular meeting in measuring process, causes the oil level test inaccurate, brings hidden danger for the safe and stable operation of transformer.
Summary of the invention
The utility model provides a kind of oil-filled transformer liquid level proving installation, has solved oil ga(u)ge pipe and the easy blocking problem of respirator that existing measurement mechanism exists.
The utility model is to solve above technical matters by the following technical programs:
A kind of oil-filled transformer liquid level proving installation; comprise transformer-cabinet; in transformer-cabinet, be provided with transformer oil; in transformer oil, be provided with the transformer body; the top cover of transformer-cabinet is provided with instrument connection; instrument connection is provided with the ball lever sleeve pipe; the ball lever sleeve pipe is fixedlyed connected with the top cover of transformer-cabinet by flange; be connected with transparent protective casing on the top of ball lever sleeve pipe; top at protective casing is provided with top cover; in transformer oil, be provided with ball float; ball float is connected with an end of ball lever; the other end of ball lever is movably arranged in the protective casing by instrument connection and ball lever sleeve pipe successively, and the tube wall of protective casing is provided with scale.
Between the upper end inwall of the lower end of protective casing outer tube wall and ball lever sleeve pipe, be provided with sealing shroud.
The utility model is simple in structure, adopts ball float to measure level height, measure accurately, and operation, easy for installation, cost is low, has ensured the safe and stable operation of transformer.
