With the rapid development of the photovoltaic industry, the safety of photovoltaic systems has gradually attracted the attention of the general public and has become a hot issue in the industry in recent years. Photovoltaic DC switches are used in photovoltaic systems to control the electrical connection between photovoltaic panels and inverters. Therefore, the reliability of photovoltaic DC switches is not only related to the good operation of the entire photovoltaic system, but also to the development of the photovoltaic industry. steady development. Photovoltaic DC switches face a core challenge: the required unit breaking capacity is getting larger and larger, but the size of the box housing the photovoltaic DC switches is required to be smaller and smaller. That is, the required unit breaking capacity and the compactness of photovoltaic DC switches are a pair of technical contradictions.

Commonly used photovoltaic DC switches are rotary electrical switches, which usually include one or more modular packaged contact modules and a control module for controlling the one or more contact modules, wherein the contact modules usually Containing a movable contact conductive component and a pair of static contact conductive elements, the function of the control module is to rotate the movable contact conductive component so that it can switchably conduct with the pair of static contact conductive elements or Disconnect for electrical disconnection between PV panels and inverter.

In a DC reflux, when the voltage in the loop is getting higher or the current is getting bigger, the electrical breaking will cause more arcs, and when the generated arc exceeds a certain limit, it will cause the photovoltaic DC switch to be burned or not working properly. In the field of photovoltaic switches, the performance index of breaking capacity is used to measure the safe breaking capacity of photovoltaic DC switches under predetermined voltage and current.

There are some technical means for improving the breaking capacity of photovoltaic DC switches, for example, increasing the rotation speed of the movable contact conductive components, adding magnets to guide the arc, adding arc extinguishing grids, or increasing the movable contact conductive components The diameter of the movable contact conductive element, but the above-mentioned technical means will increase the cost of the photovoltaic DC switch or increase the size of the photovoltaic DC switch.

Therefore, a new type of photovoltaic DC switch is expected, which can achieve the compatibility of increasing the breaking capacity and miniaturization without greatly increasing the cost.

Application overview

As mentioned above, when the voltage in the circuit loop is higher or the current is higher, the electrical interruption will cause more arcing. That is, when the voltage in the circuit loop is getting higher or the current is getting higher and higher, the state switching of each switch layer of the rotary electrical switch will generate more arcs, and when the generated arcs exceed a certain limit, it will As a result, each switch layer is burned or cannot work normally.

The inventors of the present application found through research on the existing rotary electrical switches that there are important technical blind spots or technical biases in the existing rotary electrical switches.

Specifically, in the existing rotary electrical switch disclosed by the patent publication number CN 105742107A, those of ordinary skill in the art subconsciously believe that because of the need for high-voltage insulation, the static contact between the upper and lower switch layers There must be enough space between them to meet the insulation requirements. Therefore, in the existing rotary electrical switch, there is usually a relatively large "safety space" between the switch layers of the upper and lower layers. But in fact, this "safety space" is functionally redundant. The reason is that the upper and lower switch layers have encapsulation shells respectively. Therefore, when the upper and lower switch layers are assembled together, the static contacts of the upper and lower layers The conductive elements are insulated from each other due to the existence of the packaging shell.

Based on the general consensus that the upper and lower switch layers need to ensure high-voltage insulation, the existing rotary electrical switches usually arrange the movable contact conductive components and static contact conductive components on the same plane. For example, in the rotary electric switch disclosed by the patent publication number CN 105742107A, the housing of the switch layer of each rotary electric switch has a central seat and an outer peripheral seat extending outward from the central seat, so that the movable contact conductive assembly After being installed on the center seat and the static contact conductive element is installed on the outer peripheral seat, the movable contact conductive component and the static contact conductive element are deployed in a plane (or in other words, the static contact conductive element is located between the movable contact conductive component outside).

Those skilled in the art should know that increasing the diameter of the movable contact conductive element of the movable contact conductive assembly is an important technical means to improve the breaking capacity of the rotary electric switch. However, due to the existence of the above-mentioned technical blind spots (or technical prejudices), the technical scheme of increasing the diameter of the movable contact conductive element of the movable contact conductive assembly is almost impossible to implement in the actual industry. The reason is that once the diameter of the movable contact conductive element increases , because each component in the switch layer is deployed in one plane, this will inevitably lead to an increase in the size of the entire switch layer, which does not conform to the development trend of miniaturization of the switch layer.

After discovering the above-mentioned technical blind spots and technical prejudices, the inventor of the present application used the safe space between the static contact conductive elements of two adjacent switch layers to skillfully design the extension of the static contact conductive elements in each switch layer to In the three-dimensional space, the movable contact conductive element and the static contact conductive element are at least partially overlapped along the axial direction of the rotary electric switch. In this way, the dynamic contact conductive element can be increased. The diameter of the element does not increase the size of the housing, that is, within the limited space of the housing, the diameter of the movable contact conductive element is increased. Correspondingly, the increase of the diameter of the movable contact conductive element can increase the unit breaking capacity, therefore, the rotary electrical switch can realize the unit breaking capacity without greatly increasing the cost or even without increasing the cost. Compatibility between increase and miniaturization.

After introducing the basic principles of the application, various non-limiting embodiments of the application will be described in detail below with reference to the accompanying drawings.

The inventors of the present application found through research on the existing rotary electrical switches that there are important technical blind spots or technical biases in the existing rotary electrical switches. First of all, in the existing rotary electrical switch disclosed by the patent publication number CN 105742107A, those of ordinary skill in the art subconsciously believe that because of the need for high voltage insulation, the static contact conductive elements between the upper and lower switch layers must be There must be enough space to meet the insulation requirements. Therefore, in the existing rotary electrical switch, there is usually a relatively large "safety space" between the upper and lower switch layers. But in fact, this "safety space" is functionally redundant. The reason is that the upper and lower switch layers respectively have encapsulation shells. Therefore, when the upper and lower switch layers are assembled together, the static contacts of the upper and lower layers The conductive elements are insulated from each other due to the existence of the packaging shell. Moreover, in the existing rotary electric switch, the movable contact conductive assembly and the static contact conductive element are arranged on the same plane. For example, in the rotary electric switch disclosed by the patent publication number CN 105742107A, the housing of the switch layer has a central seat 123110 and an outer peripheral seat positioned at the outside of the central seat 123110, so that the movable contact conductive assembly is installed in the center After the seat 123110 and the static contact conductive element are installed on the outer peripheral seat, the movable contact conductive component and the static contact conductive component are arranged in a plane (or the static contact conductive component is located outside the movable contact conductive component) .

The layer is extended in such a way that in three-dimensional space, the movable contact conductive element and the static contact conductive element are at least partially overlapped along the axial direction of the rotary electrical switch. In this way, The overall size of the rotary electric switch can not be increased under the condition of increasing the diameter of the movable contact conductive element. Correspondingly, the increase of the diameter of the movable contact conductive element can increase the unit breaking capacity, therefore, the rotary electric switch can realize the increase of the unit breaking capacity and the unit breaking capacity without greatly increasing the cost. Compatibility between miniaturization.
