Description
Technical field
The present invention relates to a kind of outdoor ring network casees.
Background technique
Power distribution network, which refers to from source side (power transmission network and power generating equipment), receives electric energy, and on the spot or step by step by distribution facility
Distribute to the electric power networks of all types of user.In recent years, country continues to increase distribution network planning, construction and upgrading dynamics and with Denso
Standby R&D fund is put into, and on the basis of constantly improve and improving existing product technical level, utilizes new technology, new material, newly
Technological development is swift and violent.In terms of medium voltage switchgear equipment, important breakthrough is achieved, product is presented structure type and enriches, dielectric
Multiplicity, technical parameter and performance are promoted steadily.Current alternative equipment constantly comes out, and portioned product has reached or approaches
International most advanced level.
For raising power supply reliability, user is allow to obtain power supply from both direction, usually circularizes power supply network connection,
This power supply mode is referred to as ring network power supply.So, although general supply is single service, from each distribution branch
For but obtain being similar to the material benefit supplied power with double circuit, to improve the reliability of power supply.
With the fast development of distributed generation resource, micro-capacitance sensor, intelligent power, electric car, distribution network load rapid growth,
Significant changes are occurring for function and form, and the requirement to ring network power supply safety, reliability, adaptability is also higher and higher.
For existing looped network case in maintenance or maintenance repair, extraction is more troublesome, serious to affect maintenance effect
Rate.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of novel outdoor ring network case.
A kind of outdoor ring network case, including outer framework are equipped with several internal box in the inner cavity of the outer framework side by side, described
The two sides of the bottom of internal box are connected with sliding block, and the bottom corresponding position of outer framework is equipped with the sliding slot matched with sliding block, sliding block
Also it is connected by several limiting devices between sliding slot；The limiting device includes mandril and steel ball, the mandril it is straight
The aperture of diameter and limit hole matches, and the limit hole is located on the side wall of sliding slot, and the opening direction of limit hole is diagonally downward,
The end of mandril is connected by reset spring with the inner wall of limit hole, and the head of mandril is cased with bulbous recess, the steel ball card
It connects in bulbous recess, the exposed part of steel ball is connected on the side wall of sliding block, and the side wall of the sliding block is in the arc being recessed inwardly
Shape, and the upper end width of sliding block is less than lower end width.
Preferably, the quantity of the internal box is 3.
Preferably, the upper end of the sliding slot is equipped with guiding surface.
It preferably, further include trapezoidal support foot, the support foot is between internal box and sliding block, the upper end area of support foot
Greater than lower end area.
Preferably, the material of the internal box is hard aluminium alloy.
Mounting means one:
Internal box is installed directly into sliding slot vertically downward, the sliding block of internal box lower end resists steel ball, and steel ball is obliquely
Movement, and mandril is driven, so that mandril is retracted into limit hole, when internal box moves to bottom end, mandril pops up again, and steel ball supports
It connects on the side wall of sliding block.
Mounting means two:
Internal box is slid into sliding slot from side, steel ball is free to slide in bulbous recess, so that internal box bottom
Sliding block can be much smoother slide into sliding slot, to complete the connection of internal box and outer framework.
The utility model has the advantages that
1, compared with traditional fixed looped network case, each internal box in the present apparatus can be pulled out freely, greatly be saved
About maintenance when difficulty.
2, the cooperation of slanting mandril and steel ball is used in the present apparatus, mandril also passes through spring and is connected with limit hole, solid
When determining state, steel ball is tightly attached on the side wall of sliding block due to the effect of the elastic force of reset spring, guarantees that internal box will not occur
Double swerve, and when internal box needs to extract out, since steel ball can rotate freely, so, internal box inwardly or outwardly moves again
When dynamic, the frictional force born is force of rolling friction, can save the physical strength of operator.
3, the present apparatus, can be in such a way that vertical lower dress or side slide into when installing internal box, and connection method is more
Sample can be adapted for different operating environments, and match with a variety of jack machinisms.
