Problems solved by technology

[0002] Useless current in the circuit will cause damage to electrical products. In a circuit mixed with electromagnetic pulse current, lightning current, power frequency current, and DC, some electrical products can only allow power frequency current or DC current to pass through, and some Only lightning current and electromagnetic pulse are allowed to pass through

Embodiment Construction

[0012] According to the present invention, a current selection passes through the control assembly, such as figure 1 , 2 , 3, it includes a current sensor 1 connected to the circuit conductor 6, an electromagnet moving iron core 4, an electromagnet coil 5, and a filter 2, one end of which is connected with the current sensor 1, and the other end is passed through a signal line 3 is connected with electromagnet coil 5.

[0013] The filter of the present invention is either a high-pass filter or a low-pass filter; the low-pass filter is either a special ceramic filter or an RC component or consists of 1 / 4 wavelength lines. The electromagnet is a polarized electromagnet or a polarized relay, including an electromagnet moving iron core and an electromagnet coil.

[0014] When the circuit only allows electromagnetic pulse and lightning current to pass through, its working process: as figure 1 , 2 , 3 shown.

[0015] The current sensor 1 on the conductor 6 detects different cur...

Abstract

The invention discloses a current selection pass control assembly which comprises a current sensor connected with a circuit conductor, an electromagnet movable iron core and an electromagnet coil. The current selection pass control assembly is characterized by being provided with a filter, one end of the filter is connected with the current sensor, and the other end of the filter is connected with the electromagnet iron core through a signal wire. The filter is a high-flux filter or low-flux filter, and the low-flux filter is a special ceramic filter or an RC (Resistor / Capacitor) assembly or comprises a 1 / 4 wavelength wire. The invention has the beneficial effects that the current selection pass control assembly is arranged in the circuit, the filter filters a current signal passing through the circuit and enables the current signal not to be expected to be sent to the electromagnet coil, the electromagnet movable iron core rapidly acts to impact a mechanical tripping mechanism for disconnecting the circuit, so that the purpose of protecting electrical equipment is achieved.

Description

technical field [0001] The invention relates to a control assembly, in particular to a control assembly for selecting and passing current. Background technique [0002] Useless current in the circuit will cause damage to electrical products. In a circuit mixed with electromagnetic pulse current, lightning current, power frequency current, and DC, some electrical products can only allow power frequency current or DC current to pass through, and some Only lightning current and electromagnetic pulse are allowed to pass through. When only the passage of lightning current and electromagnetic pulse current is required, the passage of AC and DC current will cause damage to electrical equipment or even cause fire; when only the passage of AC and DC current is required, lightning current and electromagnetic pulse current will cause damage to electrical equipment Even caused a fire. Due to the limitation of volume and flow capacity, the filter cannot be used to complete this tas...
