Description

この発明は、太陽電池パネルに関する。特に、推進装置から発射されるプラズマビームに含まれる正電荷イオンによる衝突を防止する磁界シールド装置を備えた太陽電池パネルに関するものである。   The present invention relates to a solar cell panel. In particular, the present invention relates to a solar cell panel provided with a magnetic field shield device that prevents collision due to positively charged ions contained in a plasma beam emitted from a propulsion device.

人工衛星に設けられたイオン加速装置を備えた推進装置の腐食を低減するために、該面部分に対して主に平行な磁界を形成するための中間電位面を形成することが提案されている（例えば、特許文献１参照）。   In order to reduce the corrosion of a propulsion device provided with an ion accelerator provided in an artificial satellite, it has been proposed to form an intermediate potential surface for forming a magnetic field mainly parallel to the surface portion. (For example, refer to Patent Document 1).

特表２０１０−５３９３７５号公報Special table 2010-539375

人工衛星に設けられる駆動装置の１つに静電推進装置がある。静電推進装置は、高電圧を使用してイオン化室内でイオン化された作動ガスの正電荷イオンを高電圧静電界内で加速し、プラズマビームとして同装置のイオン化チャンバの開口から発射する。その反動原理により、人工衛星はプラズマビームの発射の方向と逆の方向に、加速される。   An electrostatic propulsion device is one of driving devices provided in an artificial satellite. The electrostatic propulsion device accelerates positively charged ions of the working gas ionized in the ionization chamber using a high voltage in a high-voltage electrostatic field and launches it as a plasma beam from the ionization chamber opening of the device. Due to the reaction principle, the satellite is accelerated in the direction opposite to the direction of the plasma beam emission.

静電推進装置の作動時は、プラズマビームの発射方向に向いている人工衛星の表面が腐食していくことが観測される。例えば、太陽電池セルをパネル上に搭載した太陽電池パネルの表面も、このプラズマビームに含まれる正電荷イオンの衝突によって腐食されることが観測されている。
イオンによる損傷は太陽電池パネルの発電能力に支障をきたす要因であるため、太陽電池パネルに搭載される個々の部品に対して、イオン損傷に対する対策が施されている。
例えば、太陽電池パネルの受光面側に搭載される太陽電池と、太陽電池パネル上に配線された被覆電線とは、電気的に接続するために薄い板状の金属部品を介して接続されている。この金属部品がイオンによって損傷することを防ぐため、金属部品の曝露面に樹脂性のコーティングを施すことが行われる。 During the operation of the electrostatic propulsion device, it is observed that the surface of the satellite facing the direction of the plasma beam is corroded. For example, it has been observed that the surface of a solar battery panel on which solar cells are mounted on the panel is also corroded by the collision of positively charged ions contained in this plasma beam.
Since damage due to ions is a factor that impedes the power generation capability of the solar cell panel, measures against ion damage are taken for individual components mounted on the solar cell panel.
For example, the solar cell mounted on the light-receiving surface side of the solar cell panel and the covered electric wire wired on the solar cell panel are connected via a thin plate-like metal component for electrical connection. . In order to prevent the metal part from being damaged by ions, a resinous coating is applied to the exposed surface of the metal part.

金属部品と、金属部品上に施された樹脂性のコーティングは、衛星軌道上の熱環境によって、昇温による熱膨張と、冷温による熱収縮を周期的に繰り返す。
このとき、樹脂性のコーティングの熱膨張率と金属部品の熱膨張率の間に差異があるため、その差異に応じた熱応力が樹脂性のコーティングおよび金属部品に印加される。一般に樹脂製のコーティングおよび金属部品それぞれが持つ熱膨張率の間に大きな差異があるため、熱応力による金属部品の変形よって、金属部品が破損する。
従来、金属部品の破損によって太陽電池パネル上に形成される電気回路の冗長性が喪失し、太陽電池パネルの信頼性が低下するという課題があった。
熱応力による金属部品の破損を回避するためには、樹脂製のコーティングの厚さを厳密に制御する必要があるが、要求精度でコーティングの厚さを制御することは実際状困難であり、実現は難しいという課題があった。 The metal part and the resinous coating applied on the metal part periodically repeat thermal expansion due to temperature rise and thermal contraction due to cold temperature depending on the thermal environment on the satellite orbit.
At this time, since there is a difference between the thermal expansion coefficient of the resinous coating and the thermal expansion coefficient of the metal part, thermal stress corresponding to the difference is applied to the resinous coating and the metal part. In general, since there is a large difference between the thermal expansion coefficients of the resin coating and the metal part, the metal part is damaged by the deformation of the metal part due to thermal stress.
Conventionally, there has been a problem that the redundancy of the electric circuit formed on the solar cell panel is lost due to breakage of metal parts, and the reliability of the solar cell panel is lowered.
In order to avoid damage to metal parts due to thermal stress, it is necessary to strictly control the thickness of the resin coating, but it is difficult to actually control the coating thickness with the required accuracy. There was a problem that was difficult.

この発明は係る課題を解決するためになされたものであり、静電推進装置の作動によるイオン損傷を抑え、動作の信頼性を維持できる太陽電池パネルを提供することを目的とする。   This invention was made in order to solve the subject which concerns, and it aims at providing the solar cell panel which can suppress the ion damage by the action | operation of an electrostatic propulsion apparatus, and can maintain the reliability of operation | movement.

A closed circuit composed of conductive wires connected to the conductive wires stretched along the rods and connected between the upper ends and the lower ends of the two rods, and a power source for supplying current to the closed circuit Prepare.

この発明に係る太陽電池パネルによれば、推進装置から発射されるプラズマビームに含まれる正電荷イオン衝突によって生じる太陽電池パネルの損傷を低減できる。   According to the solar cell panel of the present invention, damage to the solar cell panel caused by positive charge ion collision included in the plasma beam emitted from the propulsion device can be reduced.

図５は、図１に示した太陽電池パネル１上に設けたロッド２ａ、２ｂ、２ｃ、２ｄの４本のロッドを立上げ、磁界シールド装置５０を展開したときの外観図である。
図５のように、ロッド２ａ、２ｂ、２ｃ、２ｄは太陽電池パネル１の受光面側の４隅に設置されており、ロッド２ａと２ｂ、２ｃと２ｄがそれぞれペアのロッドとなる。 FIG. 5 is an external view of the four rods 2a, 2b, 2c, and 2d provided on the solar cell panel 1 shown in FIG.
As shown in FIG. 5, the rods 2a, 2b, 2c, and 2d are installed at the four corners on the light receiving surface side of the solar cell panel 1, and the rods 2a and 2b, 2c and 2d form a pair of rods.

ロッド２ａの先端部では、被覆導線３ａｂおよび４ａが電気的に接続される構造で固定されている。被覆導線３ａｂはロッド２ｂの先端部に接続されており、４ａはロッド２ａの内部から太陽電池パネル１の受光面に配線され、さらに太陽電池パネル１の受光面から裏面への貫通穴を通って裏面側に配線され、電気コネクタ５に接続されている。   At the tip of the rod 2a, the covered conductors 3ab and 4a are fixed in a structure that is electrically connected. The coated conductor 3ab is connected to the tip of the rod 2b, 4a is wired from the inside of the rod 2a to the light receiving surface of the solar cell panel 1, and further passes through a through hole from the light receiving surface of the solar cell panel 1 to the back surface. It is wired on the back side and connected to the electrical connector 5.

ロッド２ｂの先端部で被覆導線３ａｂおよび４ｂが電気的に接続される構造で固定されており、被覆導線４ｂは被覆導線４ａと同様にロッド２ｂの内部を通って太陽電池パネル１の受光面から裏面へと配線され、電気コネクタ５に接続されている。   The covered conductors 3ab and 4b are fixed to each other at the tip end of the rod 2b, and the covered conductor 4b passes through the inside of the rod 2b in the same manner as the covered conductor 4a from the light receiving surface of the solar cell panel 1. Wired to the back surface and connected to the electrical connector 5.

ロッド２ａと同様に、ロッド２ｃの先端部で被覆導線３ｃｄおよび４ｃが接続されており、被覆導線３ｃｄはロッド２ｄの先端部に接続され、被覆導線４ｃはロッド２ｃの内部を通って太陽電池パネル１の受光面から裏面へと配線され、電気コネクタ５に接続されている。   Similarly to the rod 2a, the covered conductors 3cd and 4c are connected at the tip of the rod 2c, the covered conductor 3cd is connected to the tip of the rod 2d, and the covered conductor 4c passes through the inside of the rod 2c and is a solar cell panel. 1 is connected from the light receiving surface to the back surface and connected to the electrical connector 5.

またロッド２ｂと同様に、ロッド２ｄの先端部で被覆導線３ｂｃおよび４ｄが電気的に接続される構造で固定されており、被覆導線４ｄはロッド２ｄの内部を通って太陽電池パネル１の受光面から裏面へと配線され、電気コネクタ５に接続されている。   Similarly to the rod 2b, the covered conductors 3bc and 4d are fixed to each other at the tip of the rod 2d, and the covered conductor 4d passes through the inside of the rod 2d and receives the light receiving surface of the solar cell panel 1. Is wired to the back surface and connected to the electrical connector 5.

ロッド２ａおよびロッド２ｂ、被覆導線３ａｂ、４ａおよび４ｂならびに電気コネクタ５によって、太陽電池パネルの受光面に対して垂直となる閉回路が形成される。同様に、ロッド２ｃおよびロッド２ｄ、被覆導線３ｃｄ、４ｃおよび４ｄならびに電気コネクタ５によって、閉回路ａｂと並行となる閉回路が形成される。   The rod 2a and rod 2b, the covered conductors 3ab, 4a and 4b, and the electrical connector 5 form a closed circuit perpendicular to the light receiving surface of the solar cell panel. Similarly, a closed circuit parallel to the closed circuit ab is formed by the rod 2c and the rod 2d, the covered conductors 3cd, 4c and 4d, and the electrical connector 5.

このようにして形成された閉回路の電流経路において、電気コネクタ５→被覆導線４ａ→ロッド２ａ→被覆導線３ａｂ→ロッド２ｂ→被覆導線４ｂ→電気コネクタ５の方向に定電流を流すことで、太陽電池パネル１の手前から奥へと向かう方向に閉回路を鎖交する磁界が発生する。
同様に、閉回路の電流経路において、電気コネクタ５→被覆導線４ｃ→ロッド２ｃ→被覆導線３ｃｄ→ロッド２ｄ→被覆導線４ｄ→電気コネクタ５の方向に定電流を流すことで、太陽電池パネル１の手前から奥に向かう方向に閉回路を鎖交する磁界が発生する。 In the current path of the closed circuit thus formed, a constant current is passed in the direction of the electrical connector 5 → the coated conductor 4a → the rod 2a → the coated conductor 3ab → the rod 2b → the coated conductor 4b → the electrical connector 5, A magnetic field that links the closed circuit is generated in a direction from the front side to the back side of the battery panel 1.
Similarly, in a closed circuit current path, by passing a constant current in the direction of the electrical connector 5 → the coated conductor 4c → the rod 2c → the coated conductor 3cd → the rod 2d → the coated conductor 4d → the electrical connector 5, the solar panel 1 A magnetic field is generated that links the closed circuit in the direction from the front toward the back.

このふたつの閉回路を鎖交する磁界によって、太陽電池パネルの受光面と平行な方向の磁界を太陽電池パネル１の受光面上方に形成することができる。 A magnetic field in a direction parallel to the light receiving surface of the solar cell panel can be formed above the light receiving surface of the solar cell panel 1 by a magnetic field interlinking the two closed circuits.

このように、太陽電池パネル１の受光面上方に太陽電池パネルの受光面と平行な方向の磁界を形成した状態で、例えば、図５の太陽電池パネル１の左側から受光面へ向かう方向に正電荷イオンが飛来した場合、図６に示すように、正電荷イオンの軌跡１１０は、磁界シールド装置５０により形成された磁界によって、太陽電池パネル１から離れる方向へローレンツ力が正電荷イオンに働く。   Thus, in a state where a magnetic field in a direction parallel to the light receiving surface of the solar cell panel is formed above the light receiving surface of the solar cell panel 1, for example, in the direction from the left side of the solar cell panel 1 to the light receiving surface in FIG. When the charged ions fly, the Lorentz force acts on the positively charged ions in the direction away from the solar cell panel 1 by the magnetic field formed by the magnetic field shield device 50 as shown in FIG.

このようにして、本実施の形態に係る磁界シールド装置を備えた太陽電池パネルでは、太陽電池パネル１の方向に飛来した正電荷イオンが、太陽電池パネル１に衝突することを回避することできる。   Thus, in the solar cell panel provided with the magnetic field shield device according to the present embodiment, it is possible to avoid positively charged ions that have come in the direction of the solar cell panel 1 from colliding with the solar cell panel 1.
