Description

Novel drop type fuse
Technical field
The utility model relates to a kind of fuse switch, specifically, relate to a kind of Novel drop type fuse.
Background technology
Fuse switch is device for switching important in transmission line, and widely applies with each rank transmission line.The break-make of fuse switch is realized by the contact of the touch spring on cartridge fuse and moving contact support, utilizes the fuse in touch spring contact fuse pipe to realize the path of electric current.But along with long-time running and the use of fuse switch, constantly cut off and close that the elastic force of contact spring is weakened gradually, cause closing and can not reach demand, easily occur accident.Also there is not supervising device in existing fuse switch, timely touch spring damages can not be known in time, could find after only having power-off, is unfavorable for ensureing power supply quality.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides a kind of design science, rational in infrastructure, easy to use, reliable in quality and be convenient to the Novel drop type fuse monitored.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of Novel drop type fuse, comprise the fixed contact support and moving contact support that are arranged on insulator two ends respectively, described fixed contact support is hinged with cartridge fuse, described moving contact support is provided with touch spring, described cartridge fuse is closed by described touch spring and described moving contact support, described touch spring both sides are provided with the arc elastic anchor ear be arranged on described moving contact support, and after described cartridge fuse is closed, this arc elastic anchor ear is fastened on outside this cartridge fuse; Described moving contact support is also provided with warning device, and described warning device comprises the pressure sensor be arranged on bottom touch spring and the microprocessor module be connected with described pressure sensor, and described microprocessor module is connected with signal projector.
Based on above-mentioned, it also comprises the temperature sensor be arranged in described cartridge fuse, and described temperature sensor connects described microprocessor module.
Based on above-mentioned, described fixed contact support be provided with leading-out terminal, described moving contact support is provided with end of incoming cables.
Based on above-mentioned, described leading-out terminal and described end of incoming cables are made up of housing and wiring card be arranged in described housing respectively.
Based on above-mentioned, it also comprises rain shade, described rain shade one end and described fixed contact support hinged, the described rain shade other end is hung on described moving contact support.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model increases arc elastic anchor ear on traditional fuse switch, not only be connected with touch spring when cartridge fuse is closed, this cartridge fuse is fixed by arc elastic anchor ear simultaneously, has both realized the fixing of fuse switch, ensure fixation simultaneously, but after fuse opening, cartridge fuse departs from arc elastic anchor ear and touch spring, ensures Electrical Safety; Increase warning device furtherly, the elasticity size of monitoring touch spring, whether extremely predict fuse switch in advance; It has design science, rational in infrastructure, easy to use, reliable in quality and is convenient to the advantage monitored.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of Novel drop type fuse, comprise the fixed contact support 2 and moving contact support 3 that are arranged on insulator 1 two ends respectively, described fixed contact support 2 is hinged with cartridge fuse 4, described moving contact support 3 is provided with touch spring 31, described cartridge fuse 4 is closed by described touch spring 31 and described moving contact support 3, described touch spring 31 both sides are provided with the arc elastic anchor ear 32 be arranged on described moving contact support 3, and after described cartridge fuse 4 is closed, this arc elastic anchor ear 32 is fastened on outside this cartridge fuse 4; This Novel drop type fuse utilizes touch spring 31 and arc elastic anchor ear 32 to fix described cartridge fuse 4, when ensureing fuse switch long-time running, firmly closed; Described cartridge fuse 4 is provided with operation ring 41, for cutting off and closed fuse.
In order to the running status of Real-Time Monitoring fuse switch, described moving contact support is also provided with warning device, described warning device comprises the pressure sensor be arranged on bottom touch spring 31 and the microprocessor module be connected with described pressure sensor, and described microprocessor module is connected with signal projector; Utilize the pressure state of described pressure sensor Real-Time Monitoring touch spring 31, and carry out the collection of information by microprocessor module and upload, utilize reflector to send to staff, be convenient to the operating state connecting fuse switch in time.
Meanwhile, the temperature sensor in described cartridge fuse 4, described temperature sensor connects described microprocessor module; Utilize the temperature information in microprocessor module collection cartridge fuse 4, ensure that staff understands the operating state of fuse switch in time, ensure its stability run.
Conveniently wiring, described fixed contact support 2 is provided with leading-out terminal 21, and described moving contact support 3 is provided with end of incoming cables 33.Simultaneously for the ease of installing cable, described leading-out terminal 21 and described end of incoming cables 33 are made up of housing and wiring card be arranged in described housing respectively.
Because this fuse switch is used for outdoor greatly, being subject to the erosion of external environment, corroding this fuse switch to prevent rainwater etc.It also comprises rain shade, described rain shade one end and described fixed contact support 2 hinged, the described rain shade other end is hung on described moving contact support 3; With this whole fuse switch covered and prevent rain erosion.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
