Description
Technical field
The present invention relates to power supply more particularly to a kind of electrical automatic powerstats.
Background technique
Voltage regulation type Switching Power Supply is by full-wave rectifier, switching tube, pumping signal, freewheeling diode, energy storage inductor and filter
The shortcomings that wave capacitor composition, voltage regulation type Switching Power Supply is that there are the interference of more serious switch.In voltage regulation type Switching Power Supply, power
Switching transistor work is adjusted in state, the alternating voltage and electric current that it is generated generate spike by other components in circuit
Vibration interference is interfered and sheltered, if these interference do not take certain measure to be inhibited, eliminated and shielded, will be severely impacted
The normal work of complete machine.Additionally due to voltage regulation type Switching Power Supply oscillator does not have the isolation of Industrial Frequency Transformer, these interference will
Common frequency power network is sealed in, makes neighbouring other electronic instruments, equipment and household electrical appliance by serious interference.Mainly pass through at this stage
Isolation cover is come the case where being isolated electromagnetism, but use isolation cover there may be electromagnetic exposure and influence heat dissipation.It affects
The automatic Regulation of transformer is run, and there are rooms for improvement.
Summary of the invention
The object of the invention is that providing a kind of electrical automatic powerstat to solve the above-mentioned problems.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention includes shell, inner casing, epipleural and lower side panel, and the inside of the shell, the shell is arranged in the inner casing
Medial surface and the inner casing medial surface between be provided with gap, the upper surface and the upside of the shell and the inner casing
The downside of plate connects, and the lower end surface of the shell and the inner casing is connect with the upper side of the lower side panel, the shell with
Multiple strip-shaped holes are provided on the inner casing, the strip-shaped hole in strip-shaped hole and the inner casing on the shell shifts to install.
Specifically, the shell includes outer shell, inner layer case, riser and annular endplate, and the inner layer case is arranged described
The inside of outer shell, and the outer shell and the upper and lower side of the inner layer case are tightly connected with the annular endplate, Duo Gesuo
It states riser to be located in the strip-shaped hole, and is tightly connected with the outer shell, the inner layer case and the annular endplate, institute
Outer shell, the inner layer case, the riser and annular endplate composition sealing cavity are stated, fills conduction in the sealing cavity
Liquid.
Specifically, the inner casing is identical as the structure of the shell, and the inner casing and the shell are rectangular housing.
Specifically, the width of the strip-shaped hole is less than the distance between the adjacent surface of two adjacent strip-shaped holes.
The beneficial effects of the present invention are：
A kind of electrical automatic powerstat of the present invention passes through two side bodies of setting, and the strip-shaped hole of dislocation is arranged on shell,
Electromagnetic isolation is effectively carried out in the case where not influencing heat dissipation to realize, and conduction liquid is perfused in shell, it can
Electromagnetic exposure effectively is avoided the occurrence of, so that stability when guaranteeing transformer automatic Regulation, has the value of popularization and application.
Detailed description of the invention
Fig. 1 is top view of the invention；
Fig. 2 is main view of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings：
As depicted in figs. 1 and 2, a kind of voltage regulation type Switching Power Supply of the present invention, including shell 1, inner casing 2, epipleural 8 and lower side panel 9,
The inside of shell 1 is arranged in inner casing 2, is provided with gap 3 between the medial surface of shell 1 and the medial surface of inner casing 2, shell 1 and interior
The upper surface of shell 2 is connect with the downside of epipleural 8, and the lower end surface of shell 1 and inner casing 2 is connect with the upper side of lower side panel 9, outside
Multiple strip-shaped holes 6 are provided on shell 1 and inner casing 2, the strip-shaped hole 6 in strip-shaped hole 6 and inner casing 2 on shell 1 shifts to install, item
The width in shape hole 6 be less than two adjacent strip-shaped holes 6 the distance between adjacent surface, shell 1 include outer shell 4, inner layer case 5,
Riser 7 and annular endplate, inner layer case 5 are arranged in the inside of outer shell 4, and outer shell 4 and the upper and lower side of inner layer case 5 with annular
End plate is tightly connected, and multiple risers 7 are located in strip-shaped hole 6, and is sealed and connected with outer shell 4, inner layer case 5 and annular endplate
It connects, outer shell 4, inner layer case 5, riser 7 and annular endplate form sealing cavity, fill conduction liquid in sealing cavity, inner casing 2 and outer
The structure of shell 1 is identical, and inner casing 2 and shell 1 are rectangular housing.
Working principle of the present invention is as follows：
The interference that voltage regulation type Switching Power Supply internal pull-up circuit generates is after the shielding of inner casing 2 and shell 1, so that outside power supply not
There are interference signals.Simultaneously by the strip-shaped hole 6 shifted to install, the thermal diffusivity of shell can not be influenced.
Meanwhile conduction liquid is injected in shell 1 and inner casing 2, it can be to avoid occurring in the cavity between shell 1 and inner casing 2
Nonconducting gap, to the case where electromagnetic exposure occur.
The limitation that technical solution of the present invention is not limited to the above specific embodiments, it is all to do according to the technique and scheme of the present invention
Technology deformation out, falls within the scope of protection of the present invention.
