Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition；Breaker is divided into primary cut-out by its use range
With low-voltage circuit breaker, high-low pressure identification of boundaries is relatively fuzzyyer, and more than 3kV typically is referred to as into High-Voltage Electrical Appliances.
High-pressure vacuum breaker, which has, is adapted to frequent operation, and electric life length, repair and maintenance workload is small, reliable etc. excellent
Point is widely used；With expanding economy, the requirement to vacuum circuit breaker capacity is also increasing, except meeting national GB marks
As defined in standard outside 1 times of temperature rise, the temperature rise of the DL standards of Utilities Electric Co. to vacuum circuit breaker proposes 1.1 times of standard requirement.
Utility model content
The technical problems to be solved in the utility model be to provide it is a kind of it is simple in construction, easy to use, thermal diffusivity is high, quality is steady
Qualitative height, 1.1 times of cheap temperature rise breakers of cost of manufacture.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of 1.1 times of temperature rise breakers, including breaker body, in addition to be arranged on the breaker on breaker body
Portion's conductive mechanism, breaker bottom conductive mechanism and vacuum bubbles, breaker top conductive mechanism by upper bracket, upper contact arm and
Upper Mume flower contact composition, one end of upper contact arm are arranged on upper bracket, and upper contact arm is provided with heat emission hole；Breaker lower guide motor
Structure is made up of lower contact arm, lower Mume flower contact, undersetting and being flexible coupling, and one end of lower contact arm is arranged on undersetting, lower contact arm
Heat emission hole is provided with, undersetting is arranged on breaker body by being flexible coupling；Be all provided with upper contact arm and lower contact arm it is fluted, it is recessed
Temperature sensor is equipped with groove.
In one embodiment of the present utility model, temperature sensor is contactor temperature sensor.
In one embodiment of the present utility model, the top of temperature sensor is sealed in groove by insulating barrier.
In one embodiment of the present utility model, insulating barrier is sulfuric horizon.
Pass through above-mentioned technical proposal, the beneficial effects of the utility model are：
The utility model is rational in infrastructure reliable, and contact arm is easy for installation simple, and quality stability is high, and cost of manufacture is cheap, goes back
Temperature rise that can be to upper and lower contact arm is monitored on-line.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structure diagram；
Corresponding component title of the numeral represented by with letter in figure：
10th, breaker body 20, upper bracket 30, upper contact arm 40, upper Mume flower contact 50, lower contact arm 60, lower plum blossom touch
First 70, undersetting 80, be flexible coupling 90, vacuum bubbles.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
It is shown in Figure 1, the utility model discloses a kind of 1.1 times of temperature rise breakers, including breaker body 10, also wrap
Breaker top conductive mechanism, breaker bottom conductive mechanism and the vacuum bubbles being arranged on breaker body 10 are included, open circuit
Device top conductive mechanism is made up of upper bracket 20, upper contact arm 30 and upper Mume flower contact 40, and one end of upper contact arm 30 is installed in upper
On bearing 20, upper contact arm 30 is provided with heat emission hole (being not drawn into figure)；Breaker bottom conductive mechanism is by lower contact arm 50, lower plum blossom
Contact 60, undersetting 70 and 80 compositions that are flexible coupling, one end of lower contact arm 50 are arranged on undersetting 70, and lower contact arm 50 is provided with
Heat emission hole, undersetting 70 is by being flexible coupling 80 on breaker body 10；It is equipped with upper contact arm 30 and lower contact arm 50 recessed
Groove (is not drawn into) in figure, and temperature sensor is equipped with groove, and the top of temperature sensor is sealed in groove by insulating barrier,
Insulating barrier is silastic-layer, and insulating barrier improves security during use；Temperature sensor can monitor contact arm and lower contact arm
The temperature of itself, temperature sensor are contactor type temperature sensor.
When breaker turns on 1.1 times of specified high currents, electric current flows through band heat emission hole from multifinger upper and lower Mume flower contact
Upper and lower contact arm, heat emission hole increases conductive surface area and area of dissipation.
The surface of upper and lower contact arm prepares insulating barrier using sulfuration process, has conductive stable, rapid heat dissipation, installation maintenance side
Just the advantages that, service life is long.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
