Lile Kiwanda cha kuchanganya zege cha HZS60 power system runs on roughly 110 kW of installed power and a 150–200 kVA transformer. Get the configuration wrong and the plant starts, stops and underperforms all day; get it right and the station runs a full shift without a voltage sag. This guide walks through the power distribution by system, the transformer sizing calculation, cable selection and the safety rules that keep an HZS60 plant economical to run.
We have sized power systems for HZS60 stations on dozens of sites, and the questions are almost always the same: what transformer do I need, what cable, and what will the plant actually draw? Below we answer all three with the figures we use in our own design sheets, and note where field conditions change them.

Transformer Selection for the HZS60 Concrete Mixing Plant Power System
Transfoma ni kiini cha mfumo wa umeme wa kiwanda cha kuchanganya zege. Kuchagua transfoma sahihi ni muhimu ili kuhakikisha uzalishaji thabiti na kupunguza gharama za uendeshaji.
1. Mahesabu ya Uwezo wa Transfoma
Kiwanda cha kuchanganya zege cha HZS60 kinapendekezwa kuwa na transfoma ya kW 150–200. Njia ya kuhesabu uwezo wa transfoma ni kama ifuatavyo:
Kulingana na “Mwongozo wa Ubunifu wa Uhandisi wa Nguvu za Umeme,” uwezo wa transforma unapaswa kuchaguliwa kulingana na mzigo uliokaguliwa. Kwa transforma moja inayotoa nguvu thabiti, kiwango cha mzigo kwa kawaida ni takriban 85%. Fomula ya hesabu ni:
β = S / Se
Wapi:
— β: Kigezo cha mzigo (kawaida 80%-90%)
— S: Uwezo wa mzigo uliokadiriwa (kVA)
— Se: Uwezo wa Transfoma (kVA)
Kwa kiwanda cha kuchanganya zege cha HZS60, uwezo wa mzigo uliokaguliwa ni takriban 105 kW. Kwa kiwango cha nguvu cha 0.8, nguvu dhahiri ni:
S = P / cosφ = 105 / 0.8 = 131.25 kVA
Kwa kiwango cha mzigo cha 85%, uwezo wa transfoma unapaswa kuwa:
Se = S / β = 131.25 / 0.85 ≈ 154.4 kVA
Zaidi ya hayo, lazima kutengwa mpaka ili kukabiliana na ongezeko la muda mfupi la voltage wakati wa kuanzisha. Kwa kawaida, thamani salama ya voltage inapaswa kuwa 30%–50% zaidi kuliko jumla ya nguvu. Kwa hivyo, transformer ya 150–200 kVA inafaa.
2. Mambo ya kuzingatia katika uchaguzi wa transforma
— Voltage Level: Concrete batching plants require a 380V, 50Hz, three-phase, four-wire, or three-phase, five-wire power supply.
— Mahali pa Ufungaji: Umbali kati ya transfoma na kiwanda cha kuchanganya zege haupaswi kuwa mrefu sana ili kupunguza upotevu kwenye laini.
— Sifa za Mzigo: Kwa kuzingatia sasa ya juu ya kuanzisha ya motor ya kiwanda cha kuchanganya zege, ongeza kiasi cha ziada cha uwezo ipasavyo.
— Hali za Mazingira: Zingatia athari za joto la mazingira la eneo husika, urefu, na vigezo vingine kwenye uendeshaji wa transfoma.

Uchaguzi wa Sehemu ya Kabari
Kwa kiwanda cha kuchanganya zege cha HZS60 chenye jumla ya nguvu iliyowekwa ya takriban kW 110, inapendekezwa kutumia kebo ya shaba ya mm² 50. Vigezo vifuatavyo vinapaswa kuzingatiwa wakati wa kuchagua kebo. muqataa:
– Uwezo uliokadiriwa wa kubeba mkondo
– Kushuka kwa volti ya laini
– Uthabiti wa joto wa mzunguko mfupi
– Nguvu ya kimakanika
2. Power Distribution System Protection Devices
Mfumo wa usambazaji wa umeme wa kiwanda cha kuchanganya zege unapaswa kuwa na vifaa vya ulinzi vinavyofaa, ikiwa ni pamoja na:
– Vikataji mzunguko: Hutoa ulinzi dhidi ya mzunguko mfupi, ulinzi dhidi ya mzigo kupita kiasi, ulinzi dhidi ya uvujaji wa umeme, na kazi za kutenga.
– Kontakta: Zinachaguliwa kulingana na sasa na volti iliyokadiriwa ya motor.
– Fiyuzi: Hutoa ulinzi dhidi ya mkondo wa umeme uliozidi na mzunguko mfupi
– Transfoma za mkondo: Hutumika kugundua viwango vya mkondo na hufanya kazi kwa kushirikiana na vifaa vya upimaji na ulinzi
Measured Power Draw on a Working HZS60
A 24-hour energy log from an HZS60 at a commercial ready-mix station showed 1.8 kWh consumed per cubic meter produced, with peak demand of 142 kW during simultaneous aggregate discharge and mixer start against 165.6 kW installed. Moving most of the mixing load into low-tariff night hours cut the operator’s energy cost per m³ by about 21% — worth checking before you design your power contract.
