Abstract
The utility model relates to an energy-saving intelligent controller. The intelligent controller is characterized in that the intelligent controller comprise s a phase line and a zero line of a reducing transformator connected with an input terminal of a controller working power supply; and wiring terminals of the phase line and the zero line of the reducing transformator are connected with earthing capacitors respectively. The utility model adopts the technical scheme that the input terminal of the controller working power supply are connected with the wiring terminals of the phase line and the zero line of the reducing transformator, which are connected with the earthing capacitors respectively, so as to form two AC filter circuits; and the variable frequency interference waves or high-frequency interference signals brought by conducting wires are transmitted to the ground through a capacitor bypass; thereby effectively reducing the influence of the signals to the circuits, effectively reducing the vibration and generated noises of a transformer coil, and greatly reducing the energy consumption.
Description
Technical field
The utility model belongs to a kind of controller of circuit breaker, particularly relates to a kind of energy-saving intelligent controller.
Background technology
The working power current supply line of the energy-saving intelligent controller of circuit breaker usually brings frequency conversion disturbing wave or high-frequency interferencing signal at present, and power supply circuits are caused the vibration of transformer coil and produce noise, has also increased energy consumption simultaneously.
Summary of the invention
The utility model provides a kind of energy-saving intelligent controller that can effectively reduce frequency conversion disturbing wave or high-frequency interferencing signal for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes the phase line and the zero line of the step-down transformer that is connected with the controller power supply input, and each is connected with the electric capacity of a ground connection phase line of described step-down transformer respectively with the terminals of zero line.
The advantage that the utlity model has with good effect is: owing to adopted the phase line of the step-down transformer that the controller power supply input is connected and the terminals of zero line, each technical scheme of being connected with the electric capacity of a ground connection respectively, constituted two ac filter circuits, frequency conversion disturbing wave that brings by lead or high-frequency interferencing signal have been arrived the earth by capacitive bypass.Thereby reduce of the influence of these signals effectively, also reduced the noise of the vibration and the generation thereof of transformer coil effectively, reduced energy consumption widely circuit.
Description of drawings
Fig. 1 is a circuit theory winding diagram of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, be connected with C2 with the capacitor C I of ground connection PE respectively at the phase line L on the former limit of step-down transformer T that is connected with 220 volts of ac working power supply inputs of controller and the terminals of zero line N.21 volts of alternating current crimping of secondary load R of transformer T.Wherein capacitor C 1, C2 are 3KV, 10NF; Transformer soldier is S5-05B.
When line voltage occurs the interference signal frequency greater than the common-mode voltage of 1M, according to capacitance characteristic Z=1/JWC; W=2 ∏ f is low resistive state and is approximately zero, has effectively prevented the coil that interference voltage is invaded transformer T.
