Abstract
The invention provides a fully insulating metering box, comprising a box body, a porcelain bottle, a first terminal and a second terminal, wherein the porcelain bottle, the first terminal and the second terminal are arranged on the outer walls of the box body, and the first terminal and the second terminal are connected to outlet cables respectively. A base I which is formed by casting of insulating and waterproof materials is arranged on an outer wall of the box body, and the porcelain bottle, the first terminal and a line connection position of the first terminal and the outlet cable are fixed inside the base I by casting. The base I is sleeved inside a metallic housing, and the metallic housing is fixed on the box body by welding. A cable outlet terminal of the metallic housing is equipped with a sealing ring and a flange cover. In the metering box of the present invention, the porcelain bottle, the first terminal and the line connection position of the first terminal and the outlet cable are fixed inside the base by casting so that live parts in a high voltage grade are completely separated from the outside. When the second terminal is also enclosed in the metallic housing or fixed inside the base by casting, all live parts of the metering box are separated from the outside. Thus, the live parts in both grades realize totally enclosed and fully insulated effects, and application of the metering box are safer and more reliable.
Description
Technical field
The present invention relates to a kind of batch meter, the particularly a kind of batch meter that can realize all insulation.
Background technology
The high pressure electric shock accidents takes place through regular meeting, especially in the city because high pressure primary connection end exposes in existing batch meter; People entangle the live part of high pressure grade for the sake of security with gum cover, even but like this, still have some tiny seam crossings, all be breakneck if touch because of carelessness, simultaneously, moist with drench with rain, situation such as infiltration all can bring potential safety hazard.
Summary of the invention
The present invention provides all insulation batch meter of a kind of waterproof, protection against the tide and sealing.
The present invention solves the technical scheme that its problem adopts:
A kind of all insulation batch meter; Comprise the porcelain vase, primary connection end and the secondary connection end that are provided with on casing and the cabinet exterior; Said once, the secondary connection end is connected with the outlet cable respectively; It is characterized in that: said cabinet exterior is provided with the pedestal I that the cast of insulative water-proof material forms, and the line place of said porcelain vase, primary connection end and primary connection end and outlet cable is fixed in the said pedestal I by cast.
As optimal way of the present invention, the line place of said secondary connection end and secondary connection end and outlet cable is fixed on the insulative water-proof material by cast and pours into a mould in the pedestal II that forms; Said pedestal II is sleeved in the metal shell, and metal shell is weldingly fixed on the casing; The cable outlet end of said metal shell is equipped with O-ring seal and blind flange.
The invention has the beneficial effects as follows: the line place of the porcelain vase of batch meter, primary connection end and primary connection end and outlet cable all is fixed in the pedestal I by cast; The live part and the external world of batch meter high pressure grade are isolated fully, and all insulation of this high-pressure side has also reached good waterproof, protection against the tide and sealing effectiveness when removing potential safety hazard; When the line place with secondary connection end and secondary connection end and outlet cable all is closed in the metal shell or is fixed in the pedestal by cast; All live parts of batch meter all are isolated from the outside; Reach the two-stage live part and all realize the effect of totally-enclosed all insulation, use more safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention;
