Description
Technical field
The present invention relates to high pressure (3.6kV ~ 40.5kV) switch, particularly indoor high-voltage vacuum switch.
Background technology
At present, known high-voltage switch gear feature is as follows:
1. switch (can be circuit breaker, may also be on-load switch or contactor) does not combine with isolating switch as the independent component in switch cubicle, couples together during use with bus again.This just brings following problem:
A. because each element is independent, the volume taken after connecting in cabinet is very huge;
B. because each element is independent, the galvanic circle formed after connecting in cabinet is very long, tie point is many, adds caloric value, reduces current capacity;
C. isolating switch adopts single-arm rotary type mostly, and the space taken is also very large.
2. in order to reduce volume, organic insulating material is used in a large number.This just brings following problem:
A. organic insulating material is passed aging in time, especially the accelerated ageing when high temperature, and dielectric strength reduces, and easily causes breakdown accident;
B. insulating material is all generally the non-conductor of heat, and impact heat radiation, increases temperature rise;
Although 3. withdraw-type switch cabinet insulating contact and switch are combined, during operation, whole handcart to be made to move, very heavy.In addition, the contact situation of dynamic and static contact cannot be observed outside cabinet, is unfavorable for safe operation;
4. switch arc control device and the upper and lower contact arm of isolating switch and driving mechanism thereof are combined, and the upper and lower stretching motion of isolating switch contact arm, conductive parts exposes.Although compare with frame mode in the past and can save very large space, the external insulation cylinder, conductive component etc. of switch arc control device, contact arm not a sealing are cast in together, and the space taken is still larger.
5. also have and adopt upper and lower telescopic isolating switch, but upper and lower contact arm is example to be avoided mutually interfering during separating brake, alternating expression is all adopted to arrange, namely the center line of upper and lower contact arm is not in a vertical line, be placed in two parallel insulating cylinders respectively, the space taken is large, and when isolating switch closes a floodgate because of stressed not point-blank, whole pole can be caused to tilt.
6. because volume is large, quality weight, operate very difficult, be also unfavorable for electric operating isolating switch.
Utility model content
The object of the invention is to for addressing the aforementioned drawbacks and providing a kind of novel high-pressure switch.
This novel high-pressure switch comprises: directly the insulator that switch arc control device and isolating switch contact arm cylinder and conductive parts once-cast are shaped; The upper and lower isolating switch contact arm that can mutually insert and driving parts thereof; Be arranged on the two-stage bevel gear between upper and lower isolating switch power transmission shaft and upper and lower isolating switch contact arm respectively, insulate swing arm; External screw thread on upper and lower isolating switch contact arm; Be inserted into the dog link in contact arm groove; The screwed bevel gear of endoporus.
Above-mentioned a kind of novel high-pressure switch, it is characterized in that, this high-voltage switch gear also comprises: the upper and lower isolating switch contact arm of tubular that external diameter does not wait, and namely major diameter of thread is less than the internal diameter of conduction contact part.Wherein, upper and lower isolating switch contact arm is wrapped in when separating brake in an insulating cylinder.This just reaches following effect:
1. switch and isolating switch are combined as an element, arc control device, isolation contact arm insulating cylinder and conductive parts are poured into an insulator, avoids electric conductor seldom to expose simultaneously as far as possible.Like this, not recombinant multiple element when using in cabinet, reduces volume significantly, reduces cost;
2. isolating switch contact arm adopts upper and lower telescoping movement, and especially upper and lower isolating switch contact arm shares an insulating cylinder, and a contact arm can be inserted in the endoporus of another contact arm, decreases the volume taken.In addition, operationally, insulating sleeve does not bear high voltage, very little to security implication;
3. decrease the use of organic insulating material, reduce the risk of ageing of insulation;
4. can observe the contact condition of contact, ensure security of operation;
5. increase between electrified body, electrified body over the ground between air distance, more ensure safety;
6. the labour-saving kind of drive, makes operation very light, is more convenient for realizing electric operating isolating switch.

Not shown upper and lower static contact isolation switch, this is a kind of parts well known in the art, and it is arranged in switch cabinet contact box.
Below in conjunction with accompanying drawing 1 ~ accompanying drawing 3 and embodiment, the invention will be further described:
1. switch splitting or integrating lock process:
1. switch operation mechanism drives switch spindle (7) to rotate counterclockwise (see accompanying drawing 1) after closing a floodgate and starting action;
2. switch spindle (7) drives switching manipulation insulated tension pole (43) to move right by main shaft connecting lever (6);

4. after closing a floodgate, arc control device contact stage clip (44) continues to be compressed to certain degree, makes to keep certain pressure between vacuum interrupter (10) dynamic and static contact;
5. separating brake process in contrast.
2. isolating switch splitting or integrating lock process
1. when upper isolating switch power transmission shaft (11) or lower isolating switch power transmission shaft (4) (the general synchronous splitting or integrating lock of upper and lower isolating switch), rotate (see accompanying drawing 1) after being subject to the torque drive from operating mechanism, the drive bevel gear (3) that it is installed drives and is rotated by dynamic bevel gear (5);
2. upper and lower secondary drive bevel gear (17,39) is driven to rotate by dynamic bevel gear (5) by insulation swing arm (15);
3. upper and lower secondary drive bevel gear (17,39) drives upper and lower secondary to be rotated by dynamic bevel gear (20,36);
4. upper and lower secondary is by dynamic bevel gear (20,36)) the T-shaped internal thread of endoporus engages with T-shaped externally threaded on upper and lower isolating switch contact arm (27,32), promote upper and lower isolating switch contact arm (27,32) to move up and down, complete the process of splitting or integrating lock.
