Abstract

The utility model relates to a conductive tube bus with a columnar main body. The bus has an opened end, and a ventilating spacer device consisting of a waterproof ring and a ventilating net is provided on the opened end. The waterproof ring can effectively prevent rainwater from flowing into the bus, and the ventilating net can prevent foreign objects from entering the bus to reduce its heat dissipation, maintain ventilation and heat dissipation, and prevent small animals, such as rats, from entering the high-voltage switch cabinet to cause short circuit. The utility model has simple structure, good heat dissipation, and has safety.

Description

A kind of contact tube bus

Technical field

The utility model relates to the interconnection technique of power transformer and high-voltage switch gear room equipment in the power transmission and transformation technical field, and particularly a kind of contact tube bus with waterproof cooling function belongs to the improvement of prior art.

Background technology

In the existing transformer station, power transformer generally adopts rectangle copper, aluminium busbar to connect with being connected of incoming line cabinet in the high-voltage switch gear room, this rectangle copper, the loss little, conductor of aluminium busbar ampacity are big, skin effect coefficient big, radiating condition is poor, section factor is little, simultaneously, install complicated.For this reason, the applicant's the patent No. is: 01215457.1, name is called: the Chinese patent of contact tube busbar joint discloses a kind of new contact tube busbar joint, this technical scheme is to change the joint gold utensil back side into conductive plane, and utilize its securing member to lock coupled various soft or hard rectangular electric conductor, realization tubular copper pipe bus is connected with various soft or hard rectangular electric conductor, this contact tube busbar joint has compact conformation, the overcurrent effective area is big, advantage such as easy for installation, after this joint connects copper pipe bus, the port of copper pipe bus is open, though the port of this open copper pipe bus can form heat sinking function naturally, but rainwater and other foreign matters, as mouse, toys such as birds enter copper pipe bus from open port easily opening are stopped up, thereby significantly reduce the heat sinking function of copper pipe bus; If toy such as mouse, birds enters in the high-tension switch cabinet along the direction of bus, also cause the equipment short circuit in the high-tension switch cabinet easily, cause the accident.

The utility model content

The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, can prevent effectively that rainwater and other foreign matters from entering from open port, perfect heat-dissipating, safe contact tube bus.

The technical scheme that realizes the utility model purpose is: main body of the present utility model is a tubular contact tube bus, and its port is open, is coated with ventilation parting device on open port.

Ventilation parting device in the technique scheme is to be arranged in the bus port along last water proof circle and ventilation net or ventilation fence to form, and the water proof circle closely is arranged in the bus port along last, and ventilation net or ventilation fence are arranged on the water proof circle.This scheme is in level or downward state applicable to the bus port.

In order to make the utility model that better anti-rainwater effect can be arranged, on above-mentioned bus port, be connected with opening heat dissipation ventilation pipe, Open Side Down for the free end of heat dissipation ventilation pipe.The state that this scheme is in level or makes progress applicable to the bus port.

The beneficial effects of the utility model are: owing to be coated with the ventilation parting device of being made up of water proof circle and ventilation net or ventilation fence at the open port of bus, the water proof circle can stop effectively that rainwater goes in the bus from the interior longshore current of bus port, and ventilation net or ventilation fence can stop that foreign matter enters the heat sinking function that reduces bus in the bus, can keep the ventilation and heat of bus openend again, avoided toys such as mouse, birds to enter in the high-tension switch cabinet simultaneously, prevented that the equipment short circuit in the high-tension switch cabinet from causing the accident along the direction of bus; When the bus port is in level or during the state that makes progress, be connected on the bus port and the heat dissipation ventilation pipe that Open Side Down can guarantee that rainwater can not enter in the bus.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment one;

Accompanying drawing 2 is looked enlarged drawing for the right side of Fig. 1;

Accompanying drawing 3 is the structural representation of the utility model embodiment two;

Accompanying drawing 4 is the structural representation of the utility model embodiment three.

Be that the structure of netting with the employing ventilation is an example in the above-mentioned accompanying drawing 2, omitted the schematic diagram when adopting ventilation fence.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Embodiment one:

As shown in Figure 1, 2, main body of the present utility model is a tubular contact tube bus 1, be copper pipe bus in the present embodiment, its port is open, on open port, be coated with ventilation parting device, this ventilation parting device is to be arranged in bus 1 port to form along last water proof circle 2 and ventilation net 3, the also available ventilation fence of ventilation net 3 substitutes, water proof circle 2 is a ring shape, the internal diameter of its external diameter and bus 1 coincide, it is interior along last closely to be arranged on bus 1 port, and ventilation net 3 is arranged on the open port that covers contact tube bus 1 on the water proof circle 2 jointly.Present embodiment is in level or downward state applicable to the bus port, water and foreign matter are stopped by water proof circle 2 and ventilation net 3, can not enter bus 1 internal blocking bus, and ventilation net 3 has guaranteed the ventilation and heat of bus 1 open port, also avoided toy to enter equipment is short-circuited by bus, safe.

Embodiment two:

As shown in Figure 3, present embodiment is to increase heat dissipation ventilation pipe 4 on the basis of embodiment one, and heat dissipation ventilation pipe 4 one end levels are connected with bus 1 port, and Open Side Down for the other end after bending.In the present embodiment, the ventilation parting device of water proof circle 2 and ventilation net 3 compositions also can be arranged on the optional position in the heat dissipation ventilation pipe 4.Because present embodiment has connected the heat dissipation ventilation pipe 4 that Open Side Down, therefore, rainwater can not enter bus 1 inside fully, and waterproof effect is better.

Embodiment three:

As shown in Figure 4, present embodiment and embodiment two are basic identical, and its difference is that bus 1 opening makes progress, and heat dissipation ventilation pipe 4 one ends vertically are connected with bus 1 port, and also Open Side Down for the other end after bending.Therefore, present embodiment can not enter bus 1 inside fully with embodiment two the same rainwater.In the present embodiment, the ventilation parting device of water proof circle 2 and ventilation net 3 compositions also can be arranged on the optional position in the heat dissipation ventilation pipe 4.

The utility model also can have many kinds of embodiments, as long as Open Side Down for the free end of the heat dissipation ventilation pipe 4 that assurance connects.
