Abstract
The utility model provides the equal pressure cap of a kind of high voltage electric equipment test lightweight, and comprise upper and lower two parts, be respectively head and stylolitic part, described head is connected with stylolitic part, and the shape of contacting section and size are all identical; A part is had at least to be spring in described head and stylolitic part.The diameter of described cylindric spring is along with all pressure value changes, and all pressure value is larger, and the diameter of described cylindrical spring is larger.The equal pressure cap of this lightweight, cleverly in conjunction with the compressible performance of spring, makes to be in Partial shrinkage or whole compressive state when depositing.This stores being more conducive to and protection when using.Thus decreasing the use of aluminium, stainless steel metal material, response national energy-saving reduces discharging policy, reduces the material cost of the equal pressure cap of lightweight.
Description
Technical field
The utility model relates to a kind of high voltage electric equipment accessory, particularly the equal pressure cap of a kind of high voltage electric equipment test lightweight.
Background technology
At present in power test, be all adopt aluminum or the equal pressure cap of stainless steel to carry out uniform electric field, reduce corona interference.Particularly in local discharge test, equal pressure cap must be used; In withstand voltage test, for reducing corona loss, in more than 100kV withstand voltage test, also to use equal pressure cap.By the restriction of electric field coefficient of uniformity, equal pressure cap must possess certain volume, uses equal pressure cap under general 500kV, and diameter is at about 1m, and weight is at 30kg-50kg.The equal pressure cap volume and weight of other more voltage levels is larger.The use point of the equal pressure cap of lightweight is all at the top of electrical equipment, and there is the distance of 3-8 rice on distance ground, and equal pressure cap will be installed on high-altitude-electric equipment, and common experience to be sling equal pressure cap with crane, and installation personnel is taken advantage of bucket arm vehicle deallocation to close and installed.Equal pressure cap volume is large, high-altitude is installed and floated, and makes installation process length consuming time, affects test efficiency, add labour intensity.Special in high-grade voltage test, have a strong impact on the quick response of maintenance, processed in time.Storage floor space greatly, also have impact on the integrated of pilot system and lightweight development, also affects carrying out with safe fast of field trial.
Summary of the invention
The utility model proposes the equal pressure cap of a kind of high voltage electric equipment test lightweight, its object is to, overcome the problems such as equal pressure cap volume in prior art is large, weight causes greatly installation inconvenient and difficult in maintenance.
The equal pressure cap of a kind of high voltage electric equipment test lightweight, comprise upper and lower two parts, be respectively head and stylolitic part, described head is connected with stylolitic part, and the shape of contacting section and size are all identical;
A part is had at least to be spring in described head and stylolitic part.
Described head is spherical spring.
Described stylolitic part is column spring.
Described head and stylolitic part are respectively spherical spring and column spring.
Described head is hemispherical.
Described stylolitic part is cylindric.
The vertical height ratio of described head and stylolitic part is 1:1.
The diameter of described cylindric spring is along with all pressure value changes, and all pressure value is larger, and the diameter of described cylindrical spring is larger.
Select spring as the equal pressure cap material of lightweight, the weight of the equal pressure cap of lightweight can greatly be alleviated, and the equal pressure cap of the lightweight of spring materials can compress, when transporting and store, reducing the equal pressure cap of lightweight and taken up space, reducing the labour intensity of installation personnel.
Described lightweight refers to that equal pressure cap quality is light, makes equal pressure cap weight described in the utility model be about 1/3rd of the equal pressure cap weight of existing aluminum, be very easy to carrying out of field trial work by above-mentioned design.
Beneficial effect
The utility model provides the equal pressure cap of a kind of high voltage electric equipment test lightweight, and comprise upper and lower two parts, be respectively head and stylolitic part, described head is connected with stylolitic part, and the shape of contacting section and size are all identical; A part is had at least to be spring in described head and stylolitic part.The diameter of described cylindric spring is along with all pressure value changes, and all pressure value is larger, and the diameter of described cylindrical spring is larger.The equal pressure cap of this lightweight, dexterously in conjunction with the compressible performance of spring, makes to be in Partial shrinkage or whole compressive state when depositing.This stores being more conducive to and protection when using.Thus decrease the use of aluminium, stainless steel metal material, response national energy-saving reduces discharging policy, reduces the material cost of the equal pressure cap of lightweight.

Fig. 2 is the front view of the equal pressure cap of lightweight in embodiment;
Label declaration: the equal pressure cap of 1-lightweight, 11-head, 12-stylolitic part.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment one
As shown in Figures 1 and 2, the equal pressure cap of a kind of high voltage electric equipment test lightweight, comprises upper and lower two parts, and be respectively head 11 and stylolitic part 12, described head is connected with stylolitic part, and the shape of contacting section and size are all identical;
A part is had at least to be spring in described head and stylolitic part.
Described head is spherical spring.
Described stylolitic part is column spring.
Described head and stylolitic part are respectively spherical spring and column spring.
Described head is hemispherical.
Described stylolitic part is cylindric.
The vertical height ratio of described head and stylolitic part is 1:1.
The diameter of described cylindric spring is along with all pressure value changes, and all pressure value is larger, and the diameter of described cylindrical spring is larger.
Select spring as the equal pressure cap material of lightweight, the weight of equal pressure cap can greatly be alleviated, and the equal pressure cap of lightweight of spring materials can compress, when transporting and store, reduce the equal pressure cap of lightweight and taken up space, reducing the labour intensity of installation personnel.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
