Description

Linkage monitoring device for environmental condition adjustment

Technical Field

The utility model relates to an electric power box dampproofing field, more specifically relates to an environmental condition adjusts's linkage monitoring device.

Background

The power station is used as a very important ring in the power transmission process, and the temperature and humidity of the environment where the equipment is located must be ensured within a normal range in order to ensure the normal operation of the equipment in the station. Common terminal box in the transformer substation, the mechanism case, the collection accuse cabinet, the cold accuse case, electric power box such as maintenance power supply box, it is as the important carrier of a secondary equipment in the transformer substation, guaranteed that a secondary equipment does not receive the direct injury of wind and snow rainwater, but the relatively more confined environment in the box can produce the problem equally, that is in case moisture gets into in the box just more difficult to discharge, make these important secondary equipment often be in the environment that the humiture exceeds standard, even moisture can condense into dew pearl, cause very big hidden danger to the normal operating of equipment, can cause the damage of equipment even. The reason why the common direct current system in the transformer substation is grounded is that the insulation is reduced after the equipment is wetted, and dew drops on the equipment, which may cause a short circuit and even a serious accident of equipment burnout. Therefore, the temperature and the humidity in the power box body are guaranteed to be within a normal and reasonable range.

At present, the common starting damp-proof and damp-removing system method for the power box body in the transformer substation mainly adopts the following steps: the manual operation has the throwing to move back, the sensor control is automatic to throw to move back, intelligent control by temperature change is adjusted:

the heater using the manual switching mode is simple in design, as shown in fig. 1, generally, the heater is a combination mode of an alternating current power supply, an air switch and a heating plate (heating resistor), the heater method is to install the heater in an electric power box body after electrification, the heater is the most common and mainstream moisture removing mode at present, the power of the heater is from 30W to 200W, and the principle is that the relative humidity in the box body is reduced by heating local air in the box body, so that the moisture removing effect is achieved. However, operation and maintenance personnel need to return hands according to seasonal climate, operate in a heating state for a long time in most of time, are easy to overheat and damage after long time, and have potential danger to adjacent equipment.

The automatic switching of the sensor control is that the sensor is used for collecting environmental data in a space, as shown in fig. 2, and the moisture removing equipment in the space of the start-stop screen cabinet is started and stopped according to a set limit value to improve the environmental temperature and humidity state. The disadvantages are that: only one start-stop limit value can be simply set, only an automatic control mode is started by action, the sensitivity of the sensor is easily reduced due to climate change in four seasons, the action is unreliable, auxiliary measures for manual starting are not provided, and the effect is general.

The general intelligent temperature control adjusting device integrates a sensor, a controller and a memory as shown in fig. 3, can set a limit value to control the moisture-dispelling element, can set an action value according to the requirement of a user, and starts and stops the moisture-dispelling element according to the action value. The mode can also be a manual mode, namely the sensor is insensitive due to weather change, and manual switching is required according to different states to serve as an auxiliary measure. The disadvantages are as follows: 1. the environmental data lack the storage function, can't analyze its state change; 2. the set value is only one, and output branch is few, can't set up different according to the four seasons demand and open and stop the value, can't throw respectively and move back different damp-dispelling components according to different environmental change requirements, and is humanized inadequately.
