Description

Large-scale capacitor adjustable type vacuum condenser drive mechanism

Technical field

This utility model is related to regulating mechanism of capacitor, particularly large-scale capacitor adjustable type vacuum condenser drive mechanism.

Background technology

Large-scale capacitor adjustable type vacuum condenser needs to be fitted in high-power short-wave transmitter, and its capacity is mainly by rotation Turn its dynamic pole piece connecting rod being changed, due to its volume it is larger, the characteristic such as vacuum having inside it in addition, safeguard every time and Test must be ordered about to adjust selfcapacity by manpower, use extremely inconvenience, waste time and energy.

Utility model content

The purpose of this utility model is to provide a kind of large-scale capacitor adjustable type vacuum condenser drive mechanism, can generation completely For the size of manual adjustment large-scale capacitor adjustable type vacuum condenser electric capacity, use and extremely facilitate, it is time saving and energy saving.

What the purpose of this utility model was realized in：A kind of large-scale capacitor adjustable type vacuum condenser drive mechanism, The heat sensor of controller and directly contact servomotor casing, servomotor are fixedly mounted with outside servomotor casing The coaxial affixed reducer power of power drive rotating shaft be input into rotating shaft, in decelerator outside the casing of its power output rotating shaft The rotating cycle gage probe of measurable reducer power output revolving shaft revolution is installed, controller coordinates electrical connection servo electricity Motivation, heat sensor and rotating cycle gage probe, in decelerator casing near the position of reducer power output revolving shaft It is fixedly mounted with affixed shaft coupling coaxial with reducer power output revolving shaft.

The subject object thing that this utility model drives is the large-scale capacitor adjustable type being applied in high-power short-wave transmitter Vacuum condenser.Before utility model works, need to be coaxial affixed large-scale by shaft coupling by its reducer power output revolving shaft The capacitance adjustment rotating shaft that electric capacity adjustable type vacuum condenser has；After servomotor starts, controller can monitor heat Servomotor casing caloric value that quantity sensor is measured simultaneously judges whether servomotor is overheated according to caloric value, while can supervise Survey the revolution value of the reducer power output revolving shaft that rotating cycle gage probe is measured and capacitance adjustment is judged according to revolution value Whether total rotation number of turns of rotating shaft or the unit turn number of turns transfinite, and control whether servomotor reduces rotating speed or stalling then.

As can be seen here, this utility model can completely replace the big of manual adjustment large-scale capacitor adjustable type vacuum condenser electric capacity It is little, use and extremely facilitate, it is time saving and energy saving, manpower is freed from the dull work for repeating, make maintenance test electric capacity mistake The time of journey greatly shortens, and effectively improves the service life of large-scale capacitor adjustable type vacuum condenser appearance.

Description of the drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is the overall broken section structural representation of this utility model.

Specific embodiment

A kind of large-scale capacitor adjustable type vacuum condenser drive mechanism, as shown in figure 1, outside the casing of servomotor 6 It is fixedly mounted with the heat sensor of controller and the casing of directly contact servomotor 6, the power drive rotating shaft 7 of servomotor 6 The coaxial power of affixed decelerator 2 input rotating shaft, is installed with measurable in decelerator 2 outside the casing of its power output rotating shaft The rotating cycle gage probe 3 of the power output rotating shaft revolution of decelerator 2, controller coordinates electrical connection servomotor 6, heat Sensor and rotating cycle gage probe 3, are fixedly mounted with the casing of decelerator 2 near the position of the power output rotating shaft of decelerator 2 With the coaxial affixed shaft coupling 4 of the power output rotating shaft of decelerator 2.

As shown in figure 1, large-scale capacitor adjustable type vacuum condenser by it is existing by electric capacity housing 5 be fitted in electric capacity housing The dynamic pole of non-touching electric capacity in 5（Plate）Component 10 and the quiet pole of electric capacity（Plate）The grade of component 11 is constituted, this utility model of electric capacity housing 5 The power output rotating shaft of decelerator 2 by shaft coupling 4 connect large-scale capacitor adjustable type vacuum condenser capacitance adjustment rotating shaft 8, The front end of electric capacity housing 5 that large-scale capacitor adjustable type vacuum condenser is provided with is fixed with and covers capacitance adjustment rotating shaft 8, electric capacity housing 5 Rear end is fixed with base 12, and capacitance adjustment rotating shaft 8 has through the perforation of the front end shell wall of tubbiness dust cover 9 with the front end of electric capacity housing 5 Some to bore a hole and coordinated with the two perforation dynamic sealing in the way of rotation, tubbiness dust cover 9 is accordingly covered and holds the one of regulation rotating shaft Part shaft part plays dust-proof effect then with the perforation that the front end of electric capacity housing 5 has.When servomotor 6 by decelerator 2, Capacitance adjustment rotating shaft 8 drives the dynamic pole of electric capacity（Plate）The quiet pole of the relative capacity of component 10（Plate）During 11 rotation of component, electric capacity moves pole（Plate） Component 10 and the quiet pole of electric capacity（Plate）The relative effective area of component 11 is increased or decreased, and capacitance size is changed then, it is intended to guarantee The rotating speed of servomotor 6 is in the range of itself can bear and guarantees that the rotating speed of capacitance adjustment rotating shaft 8 is controlled in large-scale capacitor In the range of adjustable type vacuum condenser can bear.
