The power shaking is a common name of voltage dip/dip, and generally refers to a power quality event that the effective value of the voltage drops to 10 to 90 percent of the rated value and the typical duration is 10 to 600 ms. A severe voltage sag will stop the operation of the electrical equipment being used, or cause a reduction in the quality of the product being produced. The severity of the voltage sag effect varies with the characteristics of the consumer. For industries with high continuity requirements, the hazards of "power-on-earth" are great, and these hazards are particularly apparent in low voltage (0.4kV) systems with many industrial process equipment. Therefore, the "anti-interference" of the low voltage system becomes a problem to be solved urgently.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, an anti-interference electricity module with a significant energy saving effect includes a housing 1, an expansion board 2 is disposed on one side of the housing 1, a panel 3 is mounted on one side of the expansion board 2 through a bolt, a contactor, a CPU and an auxiliary coil are mounted inside the housing 1, the module starts an "energy saving operation mode" after an ac power supply is connected through the auxiliary coil and the module works normally, that is, the module outputs a dc power to be applied to the auxiliary coil of the contactor, and the power consumption of the coil of the contactor in the energy saving operation mode can be saved by at least 80%.

Further, a display panel 4 is disposed on one side of the panel 3, and a nixie tube 5 is disposed on one side of the display panel 4 for displaying a voltage value.

Furthermore, a plurality of wiring ports 8 are formed in the two sides of the panel 3, fastening bolts are connected to the internal threads of the wiring ports 8, and the wiring ports 8 are convenient for a user to perform wiring of the anti-interference electricity module.

The working principle is as follows: when in use, the anti-interference electric module monitors real-time parameters by a CPU in the module through an analog-to-digital conversion circuit by acquiring analog quantity and switching quantity such as system voltage, contactor control loop state, related switching position and the like, thereby realizing real-time monitoring of system voltage and contactor control loop state, starting 'contactor energy-saving operation mode' by the anti-interference module when the system voltage is normal, greatly reducing power consumption when the contact works in a direct current power supply state, when the system is in power-on failure, the power supply of the contactor coil is switched to the power supply in the module, so that the contactor is maintained in a normal power-on state in the process of voltage sag, the contactor is ensured not to be tripped due to power-on failure, for a variable-frequency starting loop and an energy-saving contactor loop, because the working principle of the contactor is different from that of a common contactor, the working principle of an anti-interference module is also different: when the anti-interference module detects interference, the contact is closed, the voltage of the coil of the contactor fluctuates for a short time to restore to normal, the alternating current contactor is powered by an alternating current power supply when in normal operation, the alternating current impedance of the auxiliary coil is far larger than the direct current resistance, namely, the power consumption of the anti-interference module is far larger than the working process of the function of the contactor energy-saving operation mode of the anti-interference module when the anti-interference module operates on the alternating current power supply under the condition of operating on the direct current power supply: after the auxiliary coil is connected with an alternating current power supply and works normally, the module starts an energy-saving operation mode, namely, the module outputs direct current to be added to the auxiliary coil of the contactor.
