Description

【0001】
〔発明の属する技術分野〕
本発明は各種の事業所等で使用されている電力を有効に、又省エネルギー化に、又経費の削減に各種の情報を管理し、受電設備を高信頼化し、高圧装柱形とし、更高所作業車や温度の遠隔測定等により、従来の高圧キュービクル形受電設備と同等以上の信頼性を確保したものであり、全ての建築構造物に共通する。
【0002】
〔従来の技術〕
従来高圧受電設備(6.6KU級等)は、キュービクル形(鉄板閉鎖形)又は屋内にキュービクル形又は開放形(高圧機器を床面設置して、閉鎖していない形)が安全性の面から推奨され、装柱形は不使用化され、全くと云って良い程、見られない。
これは機器重量、高圧絶縁技術の未確立、、主しゃ断装置の未確立、保守管理(目視点検、電圧、電流漏電、温度、その他)が困難、等に対する技術手法が確立ていない為、安全性に疑問有るとされてきた理由によるものであった。
【0003】
〔発明が解決しようとする課題〕
近年の技術進歩により、機器重量の軽減化、遠距離用眼鏡の普及、電圧、電流、漏電々流等は通信技術を使用する事により携帯形の受信装置とする事も可能であり、温度は地上から放射形の温度測器で測定可能となり、又高所作業車の安全性の認知の広範化などにより、従来からの安全性に疑問有りと云う認識は成立しない。又絶縁技術は図3,4,5の如くを使用する。
従って比較的小規模の中小容量の受電設備は上述の様なシステムを利用すると従来技術に何ら劣るところは無い。
又一般に電力会社等が使用している配電に関する取扱いは大体50kw以上は高圧(6.6KU級)、50kw未満は低圧(100/200級前後)で配電すると云うもので、キュービクル形等の高圧受電設備を設置するスペースの無い事業所等では機器増設が行なえず、業務の停滞となっている等、事業活動上の懸安事項となり、深刻な側面を有している。
又高圧受電の電気料金は低圧受電に比較して割安(スケールメリットによる)に設定されており、経済性の面から、設置スペースの無い事業所でも機器増設により高圧受電する事により、電力エネルギーコストの低下を計る事が出きる等総合的に技術面から可能とし、併わせてエネルギーコストの削減を計ったもので、計算ソフトに入力するデーター及び演算式は図7,8,9の通りで極めて大きな効果があり、
本システムを設置するものは理由のいかんなく、電力エネルギーコストの低下と云う受益を差別なく、受ける事が可能となる。
又主しゃ断装置、しゃ断器内蔵の高圧開閉器も新たに高信頼性のものを用いている。
【0004】
〔課題を解決する為の手段〕
図1は受電柱のみで高圧受電設備を構成している。
近年の事業所は負荷密度が急上昇して、電力会社の一般的取扱い限界点の低圧受電容量(50kw未満)を超過するケースが多発し、受電設備設置スペースの無い事業所では業務の展開に支障をきたし、又低圧受電は電圧変動が大きい為、機器の動作も、スムーズでないケースが見られ、
又50kwを超過しそうな場合でも低圧受電をしなければならず、この為、多電力のスケールメリットである低コストな高圧の電力を使用出きず余分なエネルギーコストの負担をしなければならない場合も見られたが、受電柱一本のみの設置スペースで済む本設備は、前記問題点を一挙に解決出きるものである。
【0005】
請求項1は受電柱1本に全ての機器を装柱し、設置スペースがゼロでも高圧受電可能としたものである。
従来、安全性の点からキュービクル形に切替えされて、装柱形は無いと云って良い程になっているが、主しゃ断装置(ヒューズ付開閉器)を高信頼性の非油入機器とする事により、遠方より(双眼鏡)の目視点検及び高所作業車の安全性の実証と普及、更に計測技術の進展による各種のデータ、漏電警報等が携帯に転送可能となり、加えて温度測定に放射温度計を容易に入手出き、遠方測定可能である事等から、この様な方法を使い分けると地上設置のキュービクル形と比較し、中小規模容量での受電設備として、安全性確保に問題は無い。
高圧コンデンサーを用いる事もある。受電柱は復数本用いる事もある。
【0006】請求項2は高圧開閉器部と高圧しゃ断器部を1体化する事により、取付スペース、取付手間、設備費、美観がシンプルとなる等、の設備費の低下、美観上の問題を一挙に大巾に改善可能とする事を目的とする機器である。
【0007】請求項3は高圧機器一般に問題にされている絶縁に対する雨水の沿面導電を防ぐため水止めRを付し、その上絶縁性の物品で絶縁を保っている。雨水は水止めRの下端で滴下する。
【0008】請求項4は、〔0006〕に記載した内容を共有する。
【0009】請求項5は、 〔0007〕記載の内容の高信頼性の受電設備を構成する事が可能である。
【0010】請求項6は電気料金請求額7から高圧受電に移行する場合の模擬電気料金8を算出している。図からわかる様に35%程度の大巾な電力エネルギーコストの削減が可能で受電柱1本で構成する極限化スペースの本受電設備が中小容量事業場の高圧受電化を促進し、差別なく受益を実現出きる。
又計算に用いる図9は電気供給者が認定する土、日、祝日と平日の日数であり、35%,65%に分けて考える事が出き、B式とC式の図9下部傍記に電力量料金の違い(その他季平日12.53円/kwh,その他季7.45円/kwh,その他季とは夏季以外、夏季とは7月〜9月)を表わしている。
又各月とも平日と土、日祝の比は同じとして計算式を構成している。
Aは高圧の電気料金の計算式であり、基本料金(契約電力による)は1510円/kw,0.85は力平100%とした場合の割引係数、1.05は消費税分但し実際の各月の平日と、土日祝日の比から料金を計算し、このソフトを使用すると、更に正確な模擬計算を行なう事が可能となる。他の要素を加味したソフト例えは日毎の営業時間数を入力する場合もあり、最も正確な模擬計算が可能となる。
図8において契約電力36kwは低圧受電の従量電灯Cの29KUAと低圧電力7kwを加算している。この方法は設備費の償却を常益額から割出し可能で大きな意味を有する。現在高圧受電の契約電力は実測で決定されこれが基本料金となっているが、模擬計算において大差なく実用上問題にならない。
【0011】請求項7は本受電設備の遠隔監視、通報に関するものである。
中小規模事業場においては技術者を常駐させる事が経済的に困難である為、管理担当者に常時連絡可能とする当システムの意味は大きい。又方法としても、常識を超えた効果を期待して良い
【0012】請求項2,3に高圧しゃ断器の形式を示している。請求項2の高圧しゃ断器を用いて高圧受電設備を構成する場合は高圧開閉器と一体形の為、請求項1の高圧開閉器は不用となる。
【0013】
〔作用〕
この受電設備は高圧である為電力ロスが小さく、又電圧安定度に優れ、将来の負荷増設も容易に行なえて、省エネルギー形、キュービクルに至る高圧ケーブルが不用で柱上においても不用で劣化ケーブルによる事故が皆無、又新規の高圧しゃ断器を組み合わせて、構成するとどの部分を見ても、キュービクル式より優れている。
但し、機器重量により受電柱の荷重設計に制約を受けるので中小規模容量に適する。しかも保守管理法も前述の通り実施するので安全性に問題は無い。
又高圧受電により電力エネルギーコストも大巾に低下するので、需要が多大となる核的技術であり、加えて保守管理技術も前記の如く、確立しているので、推奨的方法である。
【0014】
〔発明の実施の形態〕
図1において積雪地帯においては電線接続は融雪等による漏電を、防止する為、防雪カバー又は絶縁テープ等の処理を実施するのが良い。
【0015】
図2は図1の単線結線図例である。変圧器は灯、動兼用形とすると、1台で済む、各種の計量値又は漏電々流警報等は、電流、漏電々流トランスジューサーで警報、通報される。
通信方法は通信線、電話線、電波、携帯電話、パソコン等に接続し、管理する。
【0016】
図3は高圧しゃ断器の内部を示している。リード線12は下端を曲げて、収納函に貫通しているがこの様にする事によりリード線を通じて、雨水が収納函に浸透するのを防止可能となり、絶縁破壊等の脅威を除去出き、又収納函材質はプラスチック等の耐候性のある材質を用いると極めて高い安全性の主しゃ断装置とする事が可能である。
一相のしゃ断器がしゃ断した場合、3相一括でしゃ断する構造としている。又負荷電流もしゃ断可能である。
【0017】
図4は主しゃ断装置底部の構造である。
電線等貫通穴14は通常碍管を取付内部を絶縁された高圧リード線を通してその上をテーピング処理している。
又収納凾内の結露による水気は、水抜き用網付蓋13を介して排出されるので内部に水がたまる事は無い。
【0018】
図5のしゃ断器内蔵の高圧開閉器は主として2つの機能を有する。一つは開閉器としての機能で高圧開閉部可動接触子17と高圧開閉部固定接触子18であり、他の一つはしゃ断器としての機能を有し、高圧しゃ断器可動接触部19と高圧しゃ断器固定接触部20と高圧しゃ断器10(ヒューズ)とで構成される。
開閉部分を2つ有するがこれは開閉器としての機能と高圧しゃ断器(ヒューズ)が一相のみ切断した場合これを検知して3相共電路から切り離す為の機能を要する為である。
別に一相のみ高圧しゃ断器(ヒューズ)が切断した場合これを検知して高圧開閉部の可動接触子17と固定接触子18をしゃ断する構造とするものもあり、この操作は機械的に行なうものと電気的に行なうものがある。
【0019】
図7は、実例としての電気料金の請求額と諸元を整理したものである。諸元は電気料金の請求書から入力したものであり、合計額を下欄に記してある。営業日数は365日/年で無休の電気使用者の例である。
【0020】
図8は0019の図7の内容の低圧受電によるものを高圧受電に置き換えた模擬の電気料金請求額の算定について記した。
総使用量は図7から転記し、これを積算法の計算式で総金額Sを求めている。
低圧受電から高圧受電に切替する事により、35%程度の電力エネルギーコストの削減が得られる。従来のキュービクル式受電では設置したスペースがとれない為と技術的安全確保に問題を有する為実現出きなかったが、本発明によるシステム又は方法を用いると一挙に高圧受電に容易に切替出きる事になり、電気使用者が受けるメリットは極めて大きい。
【0021】
図9は高圧電気を使用する場合の電気料金を算定する場合、電力会社が認めている休日と平日の日数の比較を示しており、その比は約35%〜65%となっており、その場合電力量料金は夫々、夏季平日13.89円/kwh,休日7.45円/kwh,その他季平日12.53円/kwh,休日7.45円/kwhとして、おり、0021の模擬の電気料金請求額の算定に用いられる。
云うまでもなくこの夫々の電力量単価は実際に電気供給者が用いて、請求書作成に使用している実例である。
便宜上各月とも休日と平日の比を35%:65%としたが、実際には、この比が若干異なるが、年間を通じて平均化されるので、大きな計算結果の相異を生ずる事はなく、実用上問題とならない。

[Technical field to which the invention belongs]
The present invention manages various types of information to effectively use the power used in various business establishments, save energy, and reduce costs, make the power receiving equipment highly reliable, use a high-voltage mounting type, By using a work vehicle and remote measurement of temperature, the same or higher reliability as that of the conventional high-voltage cubicle-type power receiving equipment is secured, and is common to all building structures.
[0002]
[Conventional technology]
Conventional high-voltage power receiving equipment (6.6 KU class, etc.) is cubicle type (closed iron plate) or indoor cubicle type or open type (high-pressure equipment is installed on the floor and not closed) in terms of safety. Recommended, and the pillared form is deprecated and is not seen at all.
This is because the technical methods for equipment weight, high-voltage insulation technology not established, main shut-off device not established, maintenance management (visual inspection, voltage, current leakage, temperature, etc.) are not established. For reasons that have been questioned.
[0003]
[Problems to be solved by the invention]
Due to recent technological advances, the weight of equipment can be reduced, the use of long-distance glasses has become widespread, and the use of communication technology for voltage, current, leakage current, etc. can also be used as portable receivers by using communication technology. Radiation-type temperature gauges can be measured from the ground, and the widespread awareness of the safety of working vehicles at heights cannot be construed as a question of conventional safety. The insulation technique is used as shown in FIGS.
Therefore, a relatively small and medium-sized power receiving facility is not inferior to the conventional technology when the above-described system is used.
In general, electric power companies and the like handle power distribution at a high voltage (6.6 KU class) for 50 kW or more, and a low voltage (around 100/200 class) for less than 50 kW. In places where there is not enough space to install power receiving equipment, equipment cannot be added, and operations are stagnant.
In addition, electricity charges for high-voltage power reception are set at a lower price (due to economies of scale) than low-voltage power reception. It is possible to measure the decrease in energy, and it is possible from the technical aspect as a whole, and at the same time, the energy cost is reduced. The data and calculation formulas input to the calculation software are as shown in FIGS. It has a huge effect,
Anyone who installs this system can receive the benefit of lower energy costs without discrimination for any reason.
In addition, a high reliability switch is also newly used for the main circuit breaker and high voltage switch with built-in circuit breaker.
[0004]
[Means for solving the problem]
FIG. 1 shows a high-voltage power receiving facility composed only of power receiving poles.
In recent years, the load density of business establishments has risen sharply, often exceeding the low-voltage power receiving capacity (less than 50 kW), which is the general handling limit of electric power companies. In addition, there are cases where the operation of the equipment is not smooth because the voltage fluctuation is large in the low voltage power receiving,
In addition, even if it is likely to exceed 50 kW, low-voltage power must be received. Therefore, there is a case where extra energy costs must be paid because low-cost high-voltage power, which is a merit of multi-power, cannot be used. As can be seen, the present installation, which requires only one installation space for the power receiving pole, can solve the above problems at once.
[0005]
In claim 1, all the devices are mounted on one power receiving pole, and high voltage power receiving is possible even when the installation space is zero.
Conventionally, the cubicle type has been switched to the cubicle type from the viewpoint of safety, and it is almost as if there is no pillar type. However, the main disconnecting device (switch with fuse) is a highly reliable non-oil-filled device. As a result, visual inspection of (binoculars) from a distance and demonstration and spread of the safety of aerial work vehicles, as well as various data and leakage alarms etc. due to the advancement of measurement technology can be transferred to mobile phones, and radiated to temperature measurement Since a thermometer can be easily obtained and can be measured from a distance, it is safe to use a different type of method as compared to a cubicle type installed on the ground as a small-to-medium-scale capacity power receiving facility, and there is no problem in ensuring safety. .
Sometimes a high voltage condenser is used. The power pole may be used several times.
A second aspect of the present invention is that the high-voltage switch unit and the high-pressure circuit breaker unit are integrated into one unit, so that the installation space, the installation labor, the equipment cost, and the aesthetic appearance are simplified, and the equipment cost is reduced, and there is an aesthetic problem. It is a device that aims to make it possible to greatly improve at once.
A third aspect of the present invention is to provide a water stop R for preventing creeping conduction of rainwater with respect to insulation, which is generally regarded as a problem in high voltage equipment, and furthermore, insulation is maintained by an insulating article. Rainwater drops at the lower end of the water stop R.
[0008] Claim 4 shares the contents described in [0006].
According to a fifth aspect of the present invention, it is possible to constitute a highly reliable power receiving facility described in [0007].
Claim 6 calculates a simulated electricity bill 8 when the electricity bill 7 is shifted to high-voltage power reception. As can be seen from the figure, it is possible to reduce power energy costs by as much as 35%, and this power receiving facility in an extremely limited space consisting of a single power receiving pole promotes high-voltage power receiving at small and medium capacity business sites and benefits without discrimination. Realize that.
FIG. 9 used in the calculation shows the number of days on Saturdays, Sundays, holidays and weekdays approved by the electricity supplier, which can be considered in 35% and 65%. 3 shows the difference in the electricity charge (others weekdays: 12.53 yen / kwh, other seasons: 7.45 yen / kwh, other seasons other than summer, summer: July to September).
In each month, the formulas are constructed assuming that the ratio of weekdays to Saturdays and Sundays and holidays is the same.
A is a formula for calculating a high-voltage electricity rate. The basic rate (depending on the contracted electricity) is 1510 yen / kw, 0.85 is the discount coefficient when the power flat is 100%, and 1.05 is the consumption tax but the actual consumption tax. By calculating the fee from the ratio of weekdays to weekends and holidays of each month, and using this software, it is possible to perform more accurate simulation calculations. In the case of software that takes other factors into account, the number of business hours for each day may be input, so that the most accurate simulation calculation can be performed.
In FIG. 8, the contract power 36 kW is obtained by adding 29 KUA of the low-voltage power-receiving metered light C and 7 kW of low-voltage power. This method has a significant meaning because the amortization of the equipment cost can be determined from the ordinary profit. At present, the contract power for high-voltage power reception is determined by actual measurement, and this is the basic charge.
[0011] Claim 7 relates to remote monitoring and notification of the power receiving equipment.
Since it is economically difficult to have technicians stationed at small and medium-sized business establishments, the meaning of this system, which allows constant contact to the manager, is significant. As a method, an effect beyond common sense may be expected. Claims 2 and 3 show the types of high-pressure circuit breakers. When the high-voltage power receiving equipment is configured by using the high-voltage circuit breaker according to the second aspect, the high-voltage switch is integrated with the high-voltage switch, so that the high-voltage switch according to the first aspect is unnecessary.
[0013]
[Action]
This power receiving equipment has a high voltage, so it has a small power loss, excellent voltage stability, and can easily add a load in the future.It is energy saving type, and high voltage cable to cubicle is unnecessary. There are no accidents, and when combined with a new high-pressure circuit breaker, it is superior to the cubicle type in all parts.
However, the load design of the receiving pole is restricted by the weight of the equipment, so it is suitable for small and medium capacity. Moreover, since the maintenance management method is implemented as described above, there is no problem in safety.
In addition, the power and energy costs are greatly reduced by high-voltage power reception, so that this is a core technology for which demand is enormous. In addition, the maintenance management technology has been established as described above, so this is a recommended method.
[0014]
[Embodiment of the invention]
In FIG. 1, in the snow-covered area, the electric wire connection should be treated with a snow-proof cover or insulating tape or the like in order to prevent electric leakage due to snow melting or the like.
[0015]
FIG. 2 is an example of a single-line connection diagram of FIG. Assuming that the transformer is a lamp and a dual-purpose type, only one unit is required. Various weighing values or leakage current alarms are alerted and notified by current and leakage current transducers.
The communication method is to connect and manage communication lines, telephone lines, radio waves, mobile phones, personal computers, etc.
[0016]
FIG. 3 shows the inside of the high-pressure circuit breaker. The lead wire 12 is bent at the lower end and penetrates the storage box. By doing so, it is possible to prevent rainwater from penetrating into the storage box through the lead wire, and remove a threat such as insulation breakdown, If the material of the storage box is made of a weather-resistant material such as plastic, it is possible to use the main shut-off device with extremely high safety.
When a single-phase circuit breaker breaks, the three-phase circuit breaker is used. Also, the load current can be cut off.
[0017]
FIG. 4 shows the structure of the bottom of the main breaking device.
The through hole 14 such as an electric wire is usually provided with a porcelain tube, and a high-pressure lead wire whose inside is insulated is subjected to taping.
In addition, since water in the storage box due to dew condensation is discharged through the lid 13 with a drainage net, water does not accumulate inside.
[0018]
The high-voltage switch with a built-in circuit breaker shown in FIG. 5 mainly has two functions. One is a high-voltage switch movable contact 17 and a high-voltage switch fixed contact 18 that function as a switch, and the other has a function as a circuit breaker. The circuit breaker includes a fixed contact portion 20 and a high-voltage circuit breaker 10 (fuse).
It has two open / close parts, because it needs a function as a switch and a function of detecting when one phase of a high-voltage circuit breaker (fuse) is cut off and disconnecting it from the three-phase common circuit.
In addition, there is a structure in which when a high-voltage circuit breaker (fuse) of only one phase is blown, this is detected and the movable contact 17 and the fixed contact 18 of the high-voltage switching unit are cut off. This operation is performed mechanically. And there is something to electrically.
[0019]
FIG. 7 summarizes the bills and specifications of the electricity bill as an example. The specifications are entered from the bill for electricity bills, and the total amount is shown below. The number of business days is 365 days / year, and is an example of an electricity user who is always open.
[0020]
FIG. 8 shows a calculation of a simulated electricity bill in which the low voltage power receiving of the contents of FIG. 7 of 0019 is replaced with the high voltage power receiving.
The total used amount is transcribed from FIG. 7, and the total amount S is obtained using the formula of the integration method.
By switching from low-voltage power reception to high-voltage power reception, power energy cost reduction of about 35% can be obtained. The conventional cubicle-type power receiving system could not be realized because the installed space could not be taken up and there was a problem in securing technical safety, but using the system or method according to the present invention, it was possible to easily switch to high-voltage power receiving at once. Therefore, the merit of the electric user is extremely large.
[0021]
FIG. 9 shows a comparison of the number of days between a holiday and a weekday recognized by the power company when calculating the electricity rate when high-voltage electricity is used, and the ratio is about 35% to 65%. The case electricity charge is 13.89 yen / kwh for summer weekdays, 7.45 yen / kwh for holidays, 12.53 yen / kwh for other weekdays, and 7.45 yen / kwh for holidays, respectively. Used to calculate billing amount.
Needless to say, each unit price of the electric energy is an actual example used by the electricity supplier and used for billing.
For convenience, the ratio of holidays to weekdays was 35%: 65% in each month, but in reality this ratio is slightly different, but since it is averaged throughout the year, there is no significant difference in the calculation results. There is no practical problem.
