Description

Electrode replacement type preheating device for emergency generators {ELECTRODE REPLACEMENT PREHEATER FOR EMERGENCY GENERATOR}

The present disclosure relates to an electrode replacement type preheating device for an emergency generator that enables the initial start-up of an emergency generator engine to be smoothly performed even in winter by maintaining preheating so that cooling water flowing through the engine of the emergency generator does not fall below a set temperature.

Unless otherwise indicated in this specification, the contents described in this identification item are not prior art to the claims of this application, and the description in this identification item is not admitted to be prior art.

In general, an emergency generator refers to a self-generator for supplying emergency power (preliminary power) corresponding to alternative power when supply of commercial power is stopped.

Emergency generators, which are the minimum reserve power, include lighting, air conditioning, and water supply during emergency outages in buildings or facilities such as apartments, banks, office buildings, department stores, subways, hospitals, theaters, factories, broadcasting stations, newspapers, and major communication facilities. , It must be installed to prevent accidents caused by elevators, etc., and installation is compelled by various laws and regulations such as the building law and the fire law.

In case of an emergency power outage in case of an accident outage or a planned outage, it must be capable of supplying power to firefighting equipment, etc., and the emergency generator for emergency rooms and operating rooms must be able to supply power within 10 seconds.

These emergency generators are usually driven by diesel engines. Due to the characteristics of diesel engines that generate power by compressing and exploding fuel, when the engine temperature falls below 10℃, fuel compression is not properly performed, which is considerable for initial startup. There is a problem that takes time.

In order to solve this problem, the preheating device for protecting the engine of the emergency generator, which allows the initial start-up of the engine of the emergency generator to be smoothly performed in the winter, by maintaining the preheating so that the cooling water flowing through the engine of the emergency generator does not fall below the set temperature is emergency. It is installed in the generator.

The pre-heating device for protecting the engine of the emergency generator serves to maintain the pre-heating of the engine of the emergency generator over a certain temperature by heating the cooling water to a certain temperature and supplying and circulating the jacket around the engine of the emergency generator. The structure of the emergency generator, including, is already known.

In addition, in the case of the preheating device for protecting the engine of the conventional emergency generator as described above, it is difficult to visually determine the state of the coolant, and there is a problem that the coolant cannot be replaced in a timely manner.

In addition, when the cooling water is heated above the reference temperature by the preheating device, it cannot be automatically cut off, and power is wasted, and there is a limit that the normal operation of the preheating device cannot be visually confirmed.

And as another example of an emergency generator including a preheating device for protecting the engine of the emergency generator, in Korean Patent Publication No. 10-2011-0045487 (published on May 4, 2011), among the high-frequency air heating starting systems, high-frequency is output inside the cylindrical shape. Disclosed is a high frequency air heating starting system having a cylindrical high frequency air heating device composed of each work coil having a structure to be instantaneously heated, and each work coil heating plate having a temperature change by conducting the heated temperature.

However, in the case of the preheating device for protecting the engine of the conventional emergency generator as described above, the high frequency current is not only necessary but also required for cooling water as it has a structure for heating air with a work coil heating plate heat-conducted by a work coil that is heated by a high frequency current. There was a problem that the thermal efficiency is lowered than the preheating using.

Next, referring to FIG. 3, a temperature sensor 60 is further provided on the housing 10 in contact with the outer surface of the jacket 5 to sense the temperature. The temperature sensor 60 is positioned in close contact with the outer surface of the jacket 5 described above, so that the coolant temperature inside the jacket 5 is sensed and the cooling water heating is controlled according to the sensed temperature. That is, when the temperature of the coolant inside the jacket 5 is measured by the temperature sensor 60, the measured signal is transmitted to the controller (not shown), through which the first and second electrode support rods 20 and 30 to be described later. It is possible to control whether or not an alternating current is applied to the furnace, which can be formed by a normal thermostat. In addition, the above-described temperature sensor 60 has a first terminal 61 and a second terminal 62 protruding into the housing 10.

In addition, the aforementioned housing 10 includes an opening/closing portion 13 that is opened and closed for internal maintenance. Therefore, the internal maintenance is possible by opening the opening/closing part 13, so that the cost of maintenance can be reduced.

Next, referring to FIG. 4, the housing 10 is provided with first and second electrode support rods 20 and 30. The first and second electrode support rods 20 and 30 serve to detachably connect the first and second electrodes 40 and 50 to be described later on the upper ends thereof. The first and second electrode support rods 20 and 30 are installed side by side in the above-described housing 10, and one end is fixed to the through hole 12, and the coupling grooves 21 and 31 are respectively formed at the center of the housing.

The insulating member 22 serves to control whether or not the current applied to the first electrode support rod 20 is supplied to the first electrode 40. AC currents of different polarities are applied to the first and second electrode support rods 20 and 30, respectively. Current applied to the first electrode support rod 20 is transferred to the first electrode 40 by the temperature sensor 60. Supply is determined.

The display lamp 70 serves to check whether the cooling water is heated by the aforementioned first and second electrodes 40 and 50. To this end, the above-described display lamp 70 is grounded to the first electrode support rod 20 side and the second electrode support rod 30 on the upper side based on the insulating member 22, respectively. Therefore, when current is normally supplied to the first electrode 40 side, the display lamp 70 is turned on, and when the current supply to the first electrode 40 is blocked by the temperature sensor 60, the display lamp ( 70) goes out.

According to the electrode replacement type preheating device 1 for the emergency generator as described above, the first and second electrodes 40 and 50 are detachably provided at the top of the first and second electrode support rods 20 and 30, and at the same time. As the opening/closing part 13 is detached from the housing 10 where the first and second electrode support rods 20 and 30 are located, maintenance thereof is easy, and a temperature sensor 60 for detecting the temperature of the cooling water in the receiving space is provided. When the cooling water is heated above the reference temperature, the power supply to the first and second electrode support rods 20 and 30 is cut off, so that not only waste of power is prevented, but also the display lamp 70 is flashable to provide cooling water. The overall condition of the cooling water, including whether it is heated, can be visually confirmed.
