Starting Methods

As far as possible, it is advisable and of paramount importance that the starting of the electric motor can be carried out directly, that is, at full voltage. reelcraft DP7650 OLP This is the simplest method that exists, however, it is feasible only in case the starter current does not have the ability to affect your mains.

Therefore, it is very important that the current standards of the electric utility are strictly followed and respected.

In cases where the starting current of the motor is too high, some consequence may occur, such as a high voltage drop in the mains supply system, causing an interference in the equipment installed in this system and also the oversizing of the protection system, in the case of cables and contactors, which will increase the installation costs.

Due to the problems mentioned, if direct starting is not possible, it is worth using the indirect starting method compatible with the load and the motor voltage, in order to reduce the starting current. When using a starting method with reduced voltage, the starting torque of the motor will consequently be reduced.

Bi-metal Relays and Motor Circuit Breaker

The motor-breaker is a device that guarantees the control and the protection of the motor, it is fundamentally made of thermal and magnetic triggers that act in the starting of the electric motor against the burning by variation of voltage and current in the network, the elevation of temperature of the and overloads. The use of the circuit-breaker associated to the contactor allows the motor to be connected at a distance and in this circuit-breaker-contactor combination, both carry out the protection function.

The purpose of fuses is the protection of electrical systems against short circuit. In the protection of motor circuits, those of the functional class (gL), that is, with general protection function, are used. Its interruption is of delayed effect, because the motors, being inductive loads, promote current superior to the nominal one at the moment of departure. The most common delayed fuses are the NH and Delzed Diazed types. Bimetallic relays, also called overload relays, are used to protect electrical equipment from possible overload, obstructing the circuit above the rated current value. In these relays we can select any current value because its actuating current is adjustable in a range.

Como não quebrar os móveis na hora da mudança

Durante um processo de mudança, é muito comum que alguns móveis acabem sendo prejudicados ao ser realizado o deslocamento. Mas, como não quebrar os móveis na hora da mudança?

A realização de uma mudança é sempre uma correria, sendo que são muitos pertences para organizar, embalar e guardar em locais seguros a fim de preservar os objetos.

Algumas regras poderão auxiliar você a não quebrar os móveis na hora da realização da mudança e transporta-los de forma segura.

  1. Cuidados ao embalar os objetos;
  2. Identifique as caixas, para que você saiba onde encontra-se cada utensílio;
  3. Escolha caixas grandes para guardar os pertences, mas também use e abuse do plástico bolha e até mesmo de jornais. imobiliaria mogi das cruzes

Eventualmente é preciso a contratação de uma empresa especializada em mudanças, para que seus pertences sejam cuidadosamente movimentados.

A melhor forma de garantir um translado seguro, é pedir que a imobiliária Mogi das Cruzes possa auxiliar você, na escolha da empresa que ajudará a não quebrar os móveis na hora da mudança.
