Description

Technical Field

[0001] The present specification relates to the technical field of power systems, and more specifically, the present invention relates to a heating method for a terminal box and related equipment. Background Art

[0002] In the northwest region, the temperature difference between day and night varies greatly, especially when the seasons change. Inside the terminal box, condensed water vapor and frost gradually gather on the inner wall or top of the box and slowly grow. When it grows to a certain extent, its surface tension is less than its own gravity, and it falls under the action of gravity.

[0003] If water drops fall onto the terminal block of the running equipment, it may cause grounding or short circuit of the secondary circuit in the box. In serious cases, it may cause malfunction or failure of the circuit breaker to operate, causing great harm to the power grid.

[0004] However, the traditional terminal box dehumidification heating device is generally composed of only a thermostat, a single heating plate and a sensor. There are often many problems such as inaccurate temperature collection in the terminal box resulting in poor temperature control ability of the thermostat, a single heating source that cannot take into account the entire interior of the box resulting in poor flexibility, a fixed position of the heating source for a long time causing aging of nearby terminal row equipment, and poor heat conduction efficiency inside the box. Ultimately, the dehumidification heating efficiency of the device is extremely low. Summary of the invention

[0036] The embodiment of the present application provides a terminal box heating method and related equipment, which analyzes the temperature information sent by the sensor and selects the required temperature area to start heating;

[0037] According to the PLC host control heating plate to achieve regional temperature heating, more precise;

[0038] A three-dimensional heating solution is adopted to collect temperature and humidity in a multi-faceted and three-dimensional manner and heat them to achieve a balanced temperature inside the box.

[0039] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0041] The substation terminal box is the intermediate link between outdoor electrical equipment and indoor measurement, control, protection, communication and other equipment. When the air is humid, especially in the rainy season, moisture condensation and water accumulation in the outdoor terminal box can easily cause the insulation resistance of the DC secondary circuit to the ground to decrease. In severe cases, the insulation resistance drops to zero, thus forming a DC positive power supply or negative power supply grounding. If two points of DC are grounded, it will cause protection failure or malfunction, and even damage equipment, seriously threatening the safe operation of the power grid.

[0042] The terminal box is damp, causing the terminal block screws and connectors to rust, resulting in poor contact of the secondary terminals. It can also cause the current circuit terminals to heat up or even open, causing protection to fail to operate or malfunction, leading to accidents. Poor contact of control circuits, signal circuits and other terminals will cause abnormal operation of measurement and control and protection devices, erroneous signals, and cause operators to make wrong judgments and make wrong analyses.

[0043] Condensation refers to the phenomenon that water droplets condense on the surface of the inner wall of the cabinet when the temperature of the inner wall drops below the dew point temperature.

[0044] Whether condensation occurs depends on the temperature inside the box, the temperature outside the box, the relative humidity and the dew point temperature. The main reasons for condensation in the terminal box are as follows:

[0045] (1) The humidity in the area is high, the climate temperature changes greatly, the bottom of the terminal box is damp, and some cable trenches even have water accumulation.

[0046] (2) Some terminal boxes are located in the basement, where the humidity is relatively high. The temperature inside the box, especially the temperature close to the ground, is lower than the ambient temperature.

[0047] (3) Some equipment is temporarily out of service, and the temperature of the small environment in the terminal box is lower than the ambient temperature, so condensation is easily formed on its surface.

[0048] For actual situations such as failure of the outdoor terminal box heater of the substation and failure of the temperature and humidity controller resulting in the heater not being put into operation or frequent failures, please refer to Figure 1 The embodiment of the present application provides a terminal box heating method, which is applied to a host system and may specifically include:

[0050] The target radiation collection area includes "single target radiation collection area" and "collective target radiation collection area". The "collective target radiation collection area" refers to a collection of multiple "single target radiation collection areas" in a specified area. The collected data are all collected to the user end, and the user end instructs storage or sends instructions;

[0051] The acquisition and control function items mentioned here refer to "collection temperature items" and "control temperature items". The "collection temperature item" can instruct the temperature acquisition instrument on the box to collect the temperature of a fixed area and transmit it to the data management center; the "control temperature item" can instruct the temperature heater on or inside the box to heat and control a fixed area; one of the target acquisition areas is controlled by at least one acquisition and control function item;

[0052] S120, determining the time of collection and radiation heating, the number of repetitions of collection and radiation heating, and the value of collection and radiation heating for each target radiation collection area;

[0053] The so-called single target acquisition area refers to the entire range that the sensor of the terminal box can sense. This range directly affects the temperature of the terminal box, so the determination of the target acquisition area is the core key of the technology.

[0054] The collection function items include but are not limited to function options for collecting targets such as temperature, humidity, and static electricity, and also include a heating function, which determines the collection time, collection repetition times, and collection value of each target collection area, and determines the target collection area whose collection repetition times and collection value within a specific time are greater than or equal to the preset repetition times and preset values ​​as the heating area and is the target of the software.

[0055] Exemplarily, determining an area to be heated based on the heating area and each of the target acquisition areas;

[0056] S130, determining the target collection area in which the number of repetitions of the collection and radiation heating and the collection and radiation heating value within a specific time are greater than or equal to the preset number of repetitions and the preset value as the main heating area; the day and night temperature difference in the northwest region is unpredictable, and the heating area changes unpredictably, which requires data support;

[0057] S140, constructing an optimal collection and heating plan according to the values ​​of the main heating area;

[0058] A heating instruction is issued based on the optimal collection and heating plan.

[0059] Further, a region to be heated is determined based on the main heating region and each of the target radiation collection regions;

[0060] Determine the time of collection and radiation heating, the number of repetitions of collection and radiation heating, and the value of collection and radiation heating corresponding to each of the radiation collection function items based on the area to be heated;

[0061] Constructing an optimal collection and heating scheme according to the values ​​of the area to be heated;

[0062] A heating instruction is issued based on the optimal collection and heating plan.

[0063] Further, obtaining the area information of the target acquisition area;

[0064] Determining the intensity of collection and heating based on the regional information;

[0065] Determining the preset number of acquisition and heating repetitions corresponding to each target acquisition area according to the density of the acquisition and heating and the fixed number of acquisition and heating repetitions;

[0066] The intensity of collection and heating is determined by the environmental conditions of each target collection area. Many areas that are not involved in heating are

[0067] Further, counting the number of maintenance times corresponding to the target collection area in the heating area and / or the area to be heated;

[0068] When the maintenance times are greater than a preset maintenance times, the target collection area is adjusted to a high-risk heating area.

[0069] Furthermore, the host management system center also includes a data center;

[0070] The method further comprises:

[0071] The data center identifies a user level corresponding to the user terminal based on the deletion and addition information indication of the user terminal;

[0072] The data center performs desensitization processing on the deleted and added data based on the user level and the deletion and addition information instruction, wherein the desensitization processing is to filter out the exported data that the user level is not authorized to process;

[0073] Different target users correspond to different user levels, and different user levels can obtain different information. The data center can desensitize the exported data according to the user level, that is, hide or eliminate the information that cannot be obtained by the user level, so as to protect the data security in the management system.

[0076] A second determination unit determines the time of collection and radiation heating, the number of repetitions of collection and radiation heating, and the value of collection and radiation heating for each target radiation collection area;

[0077] A third determining unit determines the target acquisition area in which the number of repetitions of the acquisition and radiant heating and the acquisition and radiant heating value within a specific time are greater than or equal to the preset number of repetitions and the preset value as a main heating area;

[0078] The instruction unit constructs an optimal collection and heating plan according to the values ​​of the main heating area and issues a heating instruction based on the optimal collection and heating plan.
