Abstract

The utility model relates to a transformer vacuum measurement special-purpose tool, and belongs to the technical field of transformer equipment. The technical scheme is that the tool comprises a pipe joint (1), a vacuum diaphragm valve (2), a joint (3), a flexible pipe (4) and a Mcleod vacuum gauge (5); the pipe joint (1), the vacuum diaphragm valve (2) and the joint (3) are connected in sequence to form a pipeline switch portion arranged on a vacuum-pumping pipeline or an fuel tank body valve; the flexible pipe (4) and the Mcleod vacuum gauge (5) form a measuring control portion; the Mcleod vacuum gauge (5) and the joint (3) are mutually connected through the flexible pipe (4). The beneficial effects are that the transformer vacuum measurement special-purpose tool is simple in structure and easy in operation; the Mcleod vacuum gauge always faces downwards when data is read, so mercury is prevented from entering the fuel tank even under maloperation; a pipe clamp is added for easily controlling connection between the vacuum gauge and the fuel tank.

Description

A kind of transformer vacuum is measured special tooling
Technical field
The utility model relates to a kind of transformer vacuum and measures special tooling, belongs to the transformer equipment technical field.
Background technology
Oil-filled transformer needs oiling under certain vacuum tightness, will keep the regular hour under certain vacuum tightness for different electric pressure products, with assurance, the moisture in fuel tank is extracted out, thereby is guaranteed product quality.Using the measurement of wheat formula (mercury) vacuum meter is transformer industry surveying instrument commonly used, need avoid mercury to enter in fuel tank in use procedure.For ease of controlling vacuum tightness, surveying instrument wants relevant make and break to open control device with vacuum line, needs to make special tooling and reaches this purpose.
The utility model content
The utility model purpose is to provide a kind of transformer vacuum and measures special tooling, controls being communicated with of wheat formula vacuum meter and body, the problems referred to above that exist in the solution background technology by pipe clamp.
The technical solution of the utility model is: a kind of transformer vacuum is measured special tooling, comprise pipe adapter, vacuum diaphragm valve, joint, flexible pipe and Mai Shi vacuum meter, described pipe adapter, vacuum diaphragm valve and joint assemble into the pipeline switch part successively, be arranged on vacuum-pumping pipeline or the oil tank body valve on, described flexible pipe and Mai Shi vacuum meter form measures control section, and wheat formula vacuum meter is connected to each other by flexible pipe and joint.
Also comprise hose clamp, described hose clamp is arranged on flexible pipe.
Described wheat formula vacuum meter is located at the position of placing down.
The beneficial effects of the utility model are: simple in structure, easy operating, during reading out data, wheat formula vacuum meter is in state down all the time, even maloperation can prevent that also mercury from entering in fuel tank, increases pipe clamp and controls, and is easy to control the connection between vacuum meter and fuel tank.
Description of drawings
Fig. 1 is structural drawing of the present utility model;
In figure: pipe adapter 1, vacuum diaphragm valve 2, joint 3, flexible pipe 4, wheat formula vacuum meter 5, hose clamp 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of transformer vacuum is measured special tooling, comprise pipe adapter 1, vacuum diaphragm valve 2, joint 3, flexible pipe 4 and Mai Shi vacuum meter 5, described pipe adapter 1, vacuum diaphragm valve 2 and joint 3 assemble into the pipeline switch part successively, be arranged on vacuum-pumping pipeline or the oil tank body valve on, described flexible pipe 4 and Mai Shi vacuum meter 5 form measures control section, and wheat formula vacuum meter 5 is connected to each other by flexible pipe 4 and joint 3.
Also comprise hose clamp 6, described hose clamp 6 is arranged on flexible pipe 4.The vacuum vacuum diaphragm valve is in normally open, controls being communicated with of wheat formula vacuum meter and body by hose clamp, unclamps hose clamp during reading out data, is at ordinary times clamped condition.
Described wheat formula vacuum meter 5 is located at the position of placing down.During reading out data, wheat formula vacuum meter is in state down all the time, even maloperation can prevent that also mercury from entering in fuel tank.
