[0013] Where C is the equivalent capacitance of the electrostatic body to be released; t is the discharge time, which is positively correlated with the equivalent inductance value L and negatively correlated with the equivalent resistance values ​​R1 and R2. It is usually 3 to 5 times the time constant τ (τ = L / (R1 + R2)). The expressions for δ and ω are shown below.

[0014] ,

[0015] ;

[0016] By presetting or adjusting the equivalent resistance values ​​R1 and R2, and the equivalent inductance value L, the size of the parameters δ and ω can be adjusted, thereby controlling the electrostatic current I under the condition that the equivalent charge value Q can be estimated. 静电 size.

[0017] Furthermore, the RL series electrostatic release circuit is connected to an electrostatic release indicator.

[0018] Based on the above design, it is generally required that the shape and structure of the contact electrode that contacts the static electricity-carrying object can ensure good contact with the static electricity-carrying object without damaging the static electricity-carrying object; if used for static electricity release in the human body, the contact electrode should also be skin-friendly.

[0019] The shape and structure of the discharge electrode for releasing static electricity generally need to ensure that it does not damage the object used to release static electricity in contact with it.

[0020] In view of this, the present invention provides the following preferred device design scheme:

[0022] The inner conductive belt (3) is used for contacting the skin and is connected to one end of the inductive coil (2), and the other end of the inductive coil (2) is connected to the outer conductive belt (1).

[0023] The inner conductive strip (3) also acts as a contact electrode.

[0024] Furthermore, the electrostatic discharge indicator (6) is connected between the inductor coil (2) and the outer conductive strip (1); the outer conductive strip (1) and the electrostatic discharge indicator (6) form a second equivalent resistor R2; and the inner conductive strip (3) forms a first equivalent resistor R1.

[0025] Furthermore, the discharge electrode sheet (4) is connected to the outer conductive strip (1).

[0031] To make the features and advantages of this patent more clearly understood, the following embodiments are specifically described in detail with reference to the accompanying drawings:

[0032] like Figure 1 As shown, the basic circuit principle of the electrostatic slow release device provided in this embodiment is as follows Figure 1 As shown, the circuit comprises a contact electrode for contacting an object with static electricity, a resistor, an inductor, and a discharge electrode for discharging static electricity, forming an RL series static discharge circuit. The resistor can be considered to include a first equivalent resistance on the contact electrode side and a second equivalent resistance on the discharge electrode side.

[0033] A major advantage of the above circuit design is that the magnitude and speed of electrostatic discharge can be controlled by coordinating the resistance and inductance values.

[0034] Application scenarios include: when used for electrostatic discharge of the human body, the electrostatic discharge current should be limited to the safe current range that the human body can withstand; when used for electrostatic discharge of objects such as vehicles, the release current charge must meet the safety requirements of the work site.

[0035] The principle of its implementation is:

[0036] Assume that the electrostatic current is I 静电, the equivalent charge Q carried by the human body or vehicle, the equivalent resistances R1 and R2 of the discharge device, and the equivalent inductance L, where R1 is the equivalent resistance near the contact electrode and R2 is the equivalent resistance near the discharge electrode. The relationship between the electrostatic current and each component is as follows.

[0037] ,

[0038] Where C is the equivalent capacitance of a human body or vehicle. For example, the human body is generally 30-50 pF and is therefore predictable. t is the discharge time, typically 3-5 times the time constant τ (τ = L / (R1 + R2)). The expressions for δ and ω are shown below.

[0039] ,

[0040] .

[0041] Based on the above circuit principle, the resistance and inductance values ​​can be adjusted to control the size of the electrostatic current and thus control the size and speed of electrostatic release.

[0042] Considering general requirements, the shape and structure of the contact electrode that contacts the static electricity-carrying object should ensure good contact with the static electricity-carrying object without damaging the static electricity-carrying object; if used for discharging static electricity from the human body, the contact electrode should also be skin-friendly.

[0043] The shape and structure of the discharge electrode for releasing static electricity generally need to ensure that it does not damage the object used to release static electricity in contact with it.

[0044] In this regard, this embodiment provides Figure 2 The preferred device design shown is convenient for those skilled in the art to further understand the application prospects of the present invention, which can be used as an electrostatic slow-release ring for releasing static electricity from the human body.

[0045] The device consists of an outer conductive strip 1, an inductor coil 2, and an inner conductive strip 3, which are mounted within an insulating sheath 5. At least a portion of the inner conductive strip 3 serves as a contact electrode. The conductive strip is made of metal, and the insulating sheath can be made of rubber.

[0046] The inner conductive strip 3 is used for contact with the skin and is connected to one end of the inductive coil 2, while the other end of the inductive coil 2 is connected to the outer conductive strip 1. In this embodiment, at least a portion of the outer conductive strip 1 can be selected as a discharge electrode, or the outer conductive strip 1 can be connected to a discharge electrode sheet 4.

[0047] In the device, an electrostatic discharge indicator 6 may be connected between the inductor 2 and the outer conductive belt 1. An LED or a gas discharge tube may be selected to indicate when electrostatic discharge occurs.

[0048] In order to release the charge carried by the human body, the device is put on the human finger, which can conduct the charge carried by the human body to the inductor coil through the inner conductive belt, and then through the discharge electrode and the outer conductive belt to contact with low-potential objects such as water pipes. The inductor coil plays the role of limiting sudden changes in current, ensuring that static electricity will not cause discomfort to the human body when it is released.

[0049] This patent is not limited to the above-mentioned best implementation method. Anyone can derive various other forms of methods for achieving electrostatic sustained release based on the inspiration of this patent. All equivalent changes and modifications made within the scope of the patent application of this invention should fall within the scope of this patent.
