產(chǎn)品描述（Product Profile）

TWOR型大功率制動電阻器是專為大功率變頻制動單元及其油田鉆井電機電阻制動控制系統(tǒng)研制的不銹鋼電阻器。該產(chǎn)品由于其負載容量大、體積小、阻值穩(wěn)定、耐腐蝕、無感抗、接線方便等顯著特點，已廣泛用于礦用機車、有軌電車的制動系統(tǒng)以及石油鉆井變頻制動控制系統(tǒng)中.

TWOR type high power brake resistor is a kind of stainless steel resistor which is designed for the high power frequency conversion brake unit and the oil field drilling motor resistance brake control system. The products have large capacity, small volume, stable resistance, non-corrosion, low inductance, convenient wiring. etc, and have been widely used in the braking system of the mine locomotive, the tramcar and the oil drilling platform.

產(chǎn)品結(jié)構(gòu)特點 Structural characteristics

1. 電阻器采用模塊化設計，功率可達50kw～10000KW。

2. 采用的電阻結(jié)構(gòu)，帶式電阻片利于散熱、表面負荷大，工作時電流分布均勻；電阻片連接采用焊接方式，耐各種沖擊振動，電阻片之間采用瓷件隔離，抗震性和絕緣性良好。

3.采用*成熟的加工線，使電阻片的阻值精度控制在±2%內(nèi)，確保成品滿足阻值公差要求。另外，電阻帶使用特殊的加強筋方式，使電阻排結(jié)構(gòu)做的比較緊湊，縮小產(chǎn)品尺寸。

4.眾誠達制造的電阻，不僅選擇高標準材料和器件，而且嚴格控制各個工序零件質(zhì)量，確保每臺產(chǎn)品都高于標準要求。

5.較大功率電阻眾城達器采用強制風冷方式，以保證可靠的散熱。附加風壓開關(guān)及溫度傳感器，以保證產(chǎn)品的可靠性。

6.產(chǎn)品經(jīng)過嚴格的溫升、鹽霧、耐壓等試驗，鉆井平臺各種惡劣的工況條件。

1.The resistor adopted modular design，ａnd resistor power ：50kw～10000KW.

2．The special structure of resistor, can improve the heat dissipation capacity and have more surface load and is able to current uniform distribution; The resistor bank are connected by welding, which can endure the various shock and vibration. The resistor banks are separated by porcelain pieces, which have better vibration and insulation.

3. The advanced and mature automatic production lines are used to insure resistance tolerance≤2% .In addition, the special reinforced rib resistance belt can make resistance bank smaller and reduce the size of the product.

4.Teamwill resistor，not only choose the high standard materials and devices, but also strictly control the quality of each production process, ensure higher quality than the standard requirements.

5. The large power resistor will adopt forced air cooling mode to ensure the reliable heat dissipation. And the products install pressure switch and temperature sensor to ensure the reliability of the resistors.

6. All products subject to strict temperature rising test, salt spray test, withstａnd voltage test to ensure working normal in all kinds of bad conditions.
