Description

High ferro that fuse and temperature controller are combined into one, motor-car temperature controller

Technical field

The utility model belongs to high ferro, motor-car temperature controller, and more particularly to a kind of fuse and temperature controller close Two for one high ferro, motor-car temperature controller.

Background technology

Air-conditioning assembly or other parts easily to generate heat are assembled in high ferro, motor train compartment madial wall, are easily made Into the rise of interior compartment side wall temperature, the temperature rise of this interior compartment side wall does not allow, it is necessary to has a temperature control Device processed controls the temperature of interior compartment side wall to maintain in the range of some, and must have a temperature for being used for two level protection Fuse is spent, for preventing once temperature controller fails, endangers --- --- caused by the parts persistent fever of madial wall If temperature controller fails, circuit will be caused to be in normally off all the time, the fever that will continue, then will result in The lasting rise of interior compartment side wall temperature, when the fusing-off temperature for being increased to Thermal Cutoffs, two level is prevented in circuit for this series connection The Thermal Cutoffs of shield will fuse, and play the role of power-off, will not raise the side wall temperatures in compartment.

Traditional high ferro, the temperature controller of motor train compartment madial wall temperature control and defensive Temperature protection of two level Silk, is two parts of two diverse locations connected in circuit, it is necessary to which installation fixation twice can be completed.Such side Formula, the expense of fuse add mounting cost, every about being close on 50000 yuan or so, it is often more important that, it is divided into two positions processing It is together in series, considerably increases non-persistent risk, easily break down.And high ferro or motor-car are safeguarded once stopping, 10,000 yuan/hour of starting fare, enormous costs.

The content of the invention

It is an object of the invention to overcome above-mentioned technical deficiency, there is provided the low fuse of a kind of good airproof performance, failure rate and High ferro that temperature controller is combined into one, motor-car temperature controller.

The technical problem that the utility model solves, used technical solution are：A kind of fuse and temperature controller close Two high ferros for one, motor-car temperature controller, including sealing shell are fixed with pedestal on the right side of sealing shell, pedestal Upside is embedded in drawer at movable side metallic plate, and the right end welding travelling contact plate of drawer at movable side metallic plate, the left end riveting of travelling contact plate can Movable contact, the middle part rear side of travelling contact plate are equipped with the bimetal leaf of temperature-sensitive；The intracavitary of sealing shell on the right side of pedestal is with filling Fill out agent sealing and fix two wire columns, wire column left end above is connected with movable side terminal, wire column below and fixation Side terminal connects；There is fixed contact in the left end riveting of affixed side metallic plate；Fixed contact is in contact with travelling contact；Its feature It is to be fixed with affixed side metallic plate at sealing shell bottom surface both ends, Thermal Cutoffs is housed between affixed side metallic plate.

The beneficial effects of the utility model are that the utility model is connected one between fixed contact and affixed side metallic plate Thermal Cutoffs, the different temperature controller of traditional, installation site is closed two with the Thermal Cutoffs that second class protection acts on is As soon as a component completes the function of two components, once mounting can be completed, and reduce and be together in series because component morely Risk more than failure.

Embodiment

Embodiment, referring to the drawings, high ferro that a kind of fuse and temperature controller are combined into one, motor-car temperature control Device, including sealing shell 6, pedestal 7 is fixed with the right side of sealing shell 6, and the upside of pedestal 7 is embedded in drawer at movable side metallic plate 13, The right end welding travelling contact plate 3 of drawer at movable side metallic plate 13, the left end riveting travelling contact 2 of travelling contact plate 3, travelling contact plate The bimetal leaf 4 of temperature-sensitive is housed on rear side of 3 middle part；The intracavitary filler 9 of the sealing shell 6 on the right side of pedestal 7 is sealed and consolidated Fixed two wire columns 10,10 left end of wire column above are connected with movable side terminal 12, wire column 10 below and fixed side Son 8 connects；There is fixed contact 1 in the left end riveting of affixed side metallic plate 11；Fixed contact 1 is in contact with travelling contact 2；It is special Sign is to be fixed with affixed side metallic plate 11 at 6 bottom surface both ends of sealing shell, is protected between affixed side metallic plate 11 equipped with temperature Dangerous silk 5.

The design and operation principle of the utility model：The temperature controller of high ferro, motor train compartment madial wall temperature control, It is to be connected in series in the circuit of other parts, when the temperature of interior compartment side wall is increased to the temperature specified, bimetal leaf 4 is jumped It is disconnected, travelling contact plate 3 is lifted so that travelling contact 2 and fixed contact 1 separate, and have haveed the function that the whole circuit of cut-out, have made Obtaining temperature will not continue to rise；When interior compartment side wall temperature is reduced to the temperature specified, 4 involution of bimetal leaf, movably Contact panel 3 returns to reset condition, 1 contact closure of travelling contact 2 and fixed contact, has reached recovery by the elastic force of itself The effect of circuit；And failed for some reason if once there is bimetal leaf 4, even reach the temperature specified Do not jump disconnected, then travelling contact 2 and fixed contact 1 are in closure state, circuit continuous firing, meeting persistent fever, car all the time Wall temperature can also continue to raise on the inside of railway carriage or compartment, and when being increased to the fusing-off temperature of Thermal Cutoffs 5, Thermal Cutoffs 5 fuses, and also reaches The effect of the whole circuit of cut-out is arrived so that temperature will not continue to rise.The fusing-off temperature of typical temperature fuse 5 compares bimetallic The jump of piece 4 is broken high 10 DEG C or so of temperature.
