Description

本発明は、相間電圧200V以上の３相交流負荷試験機において市販100Vヘヤードライヤーを使用した３相交流負荷試験機に関するものである。   The present invention relates to a three-phase AC load tester using a commercially available 100 V hair dryer in a three-phase AC load tester having an interphase voltage of 200 V or more.

水抵抗負荷試験機においては水槽の持ち運び、管理、攪拌装置或いは水の調達等手間ひまかかりすぎ等で使用するのが敬遠される。ニクロム線負荷試験機に於いては構成抵抗器は手作りで、ニクロム線をコイル状に巻き且つそれの巻きつき防止、ゆれ防止、冷却等から装置が大きく重たい物になる欠点がある。それ故使用するのが敬遠される。更に、客先で設置場所等使用制限されることが多々ある。   In water resistance load testing machines, use of water tanks for carrying, managing, agitating devices, or procuring water is too much time and effort. In the nichrome wire load testing machine, the constituent resistors are handmade, and the nichrome wire is wound in a coil shape, and there is a drawback that the device becomes large and heavy due to prevention of winding, prevention of shaking, cooling and the like. Therefore, use is avoided. In addition, there are many cases where the installation location is restricted at the customer site.

本発明者は３相交流負荷試験機の構成部品を徹底的に調査し容易なとり回しに貢献できる部品は無いか、諸々にかかる費用の軽減に貢献できる部品は無いか調査した結果ヘヤードライヤーに辿り着きそれを回路構成部品として使用に成功、同時にそれらを結合分離し易いようにする配線及び器具も考案、これらを含め本発明として、ここに提案するものである。ここで使用するヘヤードライヤーとは抵抗線と送風ファン一式にし手に持て且つ商品化されたものである。 同等の形状、作用するものも同一商品とみなす。
上記回路構成物を取り付ける衝立架台、それを収納する容器も工夫、全体を収納、移動可能にした。 The present inventor thoroughly investigated the components of the three-phase AC load tester and investigated whether there are any parts that can contribute to easy handling or parts that can contribute to reduction of various costs. A wiring and a device that can be used as a circuit component, and at the same time make it easy to connect and separate them are also devised, and these are proposed here as the present invention. The hair dryer used here is a set of resistance wires and a blower fan that is held and commercialized. Equivalent shapes and working items are considered the same product.
The screen stand for mounting the circuit components and the container for storing it were devised so that the whole could be stored and moved.

本発明は法律に則って試験を受け、携帯携行品として生産されている軽量、小型、堅固、安価な量産販売商品携帯へヤードライヤーを部品として使用して組み立てている為完成した負荷試験機も軽量、小型、堅固、安価な物になった。   The present invention has been tested in accordance with the law, and is a lightweight, small, robust, inexpensive mass-produced product that is produced as a portable product. Lightweight, small, solid, and cheap.

回路を分離結合する配線一式図２か図１０差込接続器具図３、図４か図１１を使用、衝立架台２２，７３に該へヤードライヤー群２１，７２を配置、取り付け取り外し簡単な仕組み、構造にしてある。一つの衝立架台は最低でも最小単位のデルタ結線、スター結線の負荷抵抗値が構成される。負荷試験機一式は最小単位の集合和で、持ち運べる任意の物を作ることが出来る。   Wiring set for separating and coupling circuits FIG. 2 or FIG. 10 Plug connecting device FIG. 3, FIG. 4 or FIG. 11 is used. It has a structure. One screen mount is composed of the minimum unit delta connection and star connection load resistance values. A set of load testing machines is a set sum of the smallest units, and can be made to be portable.

移動に際しては、ヘヤードライヤー群２１，７２を取り付けた数機の衝立架台２２，７３を収納容器２３，７４に入れるか衝立架台からそのドライヤーを外しそれを収納容器に入れるかする。この時デルタ結線では配線一式図２か差込接続器具図３か図４、スター結線では配線一式図１０か差込接続器具図11と調整抵抗器図１２を必要数同梱。負荷試験機１式容器に入れて簡単に持ち運ぶ事が可能となり、狭い場所高所、地下等での使用制限のおそれが少なくなった。今までこの様なものは無い。  When moving, several screen racks 22 and 73 to which the hair dryer groups 21 and 72 are attached are placed in the storage containers 23 and 74, or the dryer is removed from the screen racks and placed in the storage containers. At this time, the delta connection includes the wiring diagram 2 or plug connection device 3 or 4, and the star connection includes the wiring diagram 10 or plug connection device diagram 11 and the adjustment resistor diagram 12 as required. It can be easily carried in a load tester set 1 container, and there is less risk of use restrictions in narrow places, high places, underground, etc. There is no such thing until now.

200V３相交流発電装置の負荷吸収は２通りあり大容量では図１小容量では図９のようになる。大容量を吸収させるデルタ結線一回路の構成は各相間RS,ST,TRに100Vヘヤードライヤー２個直列に入れ200V負荷を吸収させる。小容量を吸収させるスター結線一回路の構成は３相の中点Oを電気的に作るとRO,SO,TOにかかる各電圧は115Ｖとなり、ここに100Vヘヤードライヤーと15V調整抵抗器を入れて負荷吸収させる。この様にして100Vヘヤードライヤーを使用した３相200V一回路の負荷吸収が解決する。ここで注意することは負荷吸収させる一回路のヘヤードライヤーは同一メーカーで性能、品質を揃え各相均等に負荷吸収させる事。次に、持ち運びを容易にするにはドライヤーの並べ方と取り付け架台の形状吟味あわせて行い配線一式図２か図１０か差込接続器具図３か図４か図１１どれか一種類、ドライヤー群２１か７２どちらか一種類、衝立架台２２か７３どちらか一種類を選択し一緒に収納する収納容器２３か７４を作成する。配線一式、差込接続器具には開閉器13,57内蔵で負荷の増減を容易にする。   There are two types of load absorption in the 200V three-phase AC power generator, and FIG. 1 shows a large capacity and FIG. 9 shows a small capacity. The configuration of one circuit of delta connection that absorbs a large capacity is to absorb 200V load by putting two 100V hair dryers in series in each phase RS, ST, TR. The configuration of a star connection circuit that absorbs a small capacity is that the voltage applied to RO, SO, and TO becomes 115V when the midpoint O of the three phases is made electrically. Absorb the load. In this way, load absorption of a three-phase 200V single circuit using a 100V hair dryer is solved. It is important to note that the load dryer of one circuit that absorbs the load is the same manufacturer with the same performance and quality, and the load is absorbed evenly in each phase. Next, in order to make it easy to carry around, the arrangement of the dryers and the shape of the mounting base are examined together, and the wiring set FIG. 2 or FIG. 10 or the plug connection apparatus FIG. 3 or FIG. The storage container 23 or 74 is selected by selecting either one of the two or 72 and one of the screens 22 or 73 and storing them together. Wiring set, plug-in connection device has built-in switches 13 and 57 to facilitate load increase and decrease.

図１はこの発明に係る発電装置と負荷試験機２０の回路上の関係図でデルタ結線に関するものを表し、負荷試験機２０が実施例１である。     FIG. 1 is a relational diagram on a circuit of a power generation device and a load tester 20 according to the present invention, which shows the delta connection, and the load tester 20 is the first embodiment.

負荷試験機２０はヘヤードライヤー（１〜６）、配線一式図２それを取り付ける衝立架台２２とに分かれる。移動する時はヘヤードライヤー、配線一式、衝立架台をバラバラにし収納ケースに入れる。     The load tester 20 is divided into a hair dryer (1 to 6), a wiring set diagram 2 and a screen stand 22 to which it is attached. When moving, separate the hair dryer, wiring set, and screen stand in the storage case.

構成で使用するヘヤードライヤー（１〜６）は３相RS,ST,TRの相間負荷吸収を均等にする必要上、同一メーカー同一性能のものでなければならない。結線の仲介を導線14で接続されたソケット7〜12が行う。     The hair dryers (1-6) used in the configuration must be of the same manufacturer and the same performance in order to equalize the interphase load absorption of the three-phase RS, ST, TR. The sockets 7 to 12 connected by the conductive wires 14 perform the mediation of the connection.

ヘヤードライヤーを３相負荷試験機として作用させる為の配線一式を図２に示す。     A set of wirings for operating the hair dryer as a three-phase load tester is shown in FIG.

使用へヤードライヤー（１〜６）を実体配線上で固定するのではなく配線一式図２を筐体19に入れ器具化した差込接続器具図３か図４で接続するので取り付け分解がより簡単になる。筐体19には設置穴18が設けてある。分解し収納容器２３に収納することが可能となるので移動容易な負荷試験機が提供できる。    Rather than fixing the hair dryer (1-6) on the actual wiring, it is easier to install and disassemble because it is connected to the plug-in connection device shown in FIG. 3 or FIG. become. An installation hole 18 is provided in the housing 19. Since it can be disassembled and stored in the storage container 23, an easy-to-move load tester can be provided.

図９はこの発明に係る発電装置と負荷試験機７１の回路上の関係図でスター結線に関するものを表し、負荷試験機７１が実施例２である。   FIG. 9 is a relational diagram on the circuit of the power generator according to the present invention and the load tester 71, which shows the star connection, and the load tester 71 is the second embodiment.

負荷試験機７１はヘヤードライヤー（51〜53）と配線一式図１０調整抵抗器図１２それを取り付ける衝立架台７３とに分れる。移動する時はヘヤードライヤー、配線一式、衝立架台をバラバラにし収納ケースに入れる。   The load tester 71 can be divided into a hair dryer (51 to 53), a wiring set, FIG. 10, an adjusting resistor, and a screen stand 73 to which it is attached. When moving, separate the hair dryer, wiring set, and screen stand in the storage case.

構成で使用するヘヤードライヤー（５１〜53）は３相RS,ST,TRの相間負荷吸収を均等にする必要上、同一メーカー同一性能のものでなければならない。結線の仲介を導線58で接続されたソケット54〜56が行う。   The hair dryers (51 to 53) used in the configuration must have the same performance from the same manufacturer in order to equalize the load absorption between the three-phase RS, ST, and TR. The sockets 54 to 56 connected by the conductive wire 58 mediate the connection.

ヘヤードライヤーを３相負荷試験機として作用させる為の配線一式を図１０に示す。    A set of wirings for causing the hair dryer to act as a three-phase load tester is shown in FIG.

使用へヤードライヤーとそのドライヤーに掛かる電圧を調整する調整抵抗器図１２を実態配線上で固定するのではなく配線一式図１０を筐体66に入れ器具化した差込接続器具図１１で接続するので取り付け分解がより簡単になる。筐体66には設置穴65が設けてある。分解し収納容器に収納することが可能となるので移動容易な負荷試験機が提供できる。   Use hair dryer and adjusting resistor for adjusting the voltage applied to the dryer FIG. 12 is not fixed on the actual wiring, but the wiring diagram 10 is inserted into the housing 66 and connected as shown in FIG. So disassembly is easier. An installation hole 65 is provided in the housing 66. Since it can be disassembled and stored in a storage container, an easily movable load tester can be provided.
